Choosing an Automotive Scan Tool






Greetings: viewers Aerith car guy here back again with my special guest Paul, also known as a scanner dinner and we're sizing my first names. I'D say his name is not Dan, it's not Dave. It'S not Danny Danner is my last Danner's his last name, but Paul is his first name that works scanner Danner. You know my students gave me that name years ago. It'S stuck so what did they give you that new obvious reasons right? Well, what moment is playing with a scanner? Okay, which brings me to the point of this video and the point of this video is, I get asked all the time they're like hey are at the car guy, I'm thinking about buying a scanner. What should I get or what should I look for, and I thought who better to ask then yeah this guy here whose namesake happens to be scanner Danner. So what we have is he's brought some of his like really great nice high-end type scanners that he uses with professional diagnosis, and I have some of my scan tools that are definitely not on that level, but things that are more affordable for the consumer. So we're going to take those things, talk about what those capabilities are and and how they might apply to your particular situation. Now, by no means is this an endorsement of any particular type of scanner. All we're intent on doing here is talking about some of the capabilities, and you can decide for yourself whether those capabilities are worth the extra money that you might spend on. More high-end scanner sounds good. So while we go over the bench and get a look at what we've got we'll take it from there all right, Paul you've brought us some like professional-grade, wonderful scanners. Here that do all kinds of things that really the consumer doesn't mean. But I wanted you to bring these in, for the reason of so that you can make a comparison to find out what the professional has available to them and compare it to what's available in the consumer market. That'S the only reason we have these. I know I know we have some like really expensive great scanners here, but at the same time you don't necessarily need this. This is just what's out there. This is what Paul is used and we're just going to talk about that then compare it to what we have on the consumer level. Cool sounds good, fair enough you! So, let's start with this guy here. Well, this is the snap-on varus, and I think the first thing to talk about with this tool is this is more than just a scanner. This is a scanner scope and a touchscreen laptop all combined in one. So that's really why it's so expensive. So it's more like a tablet, computer than more than anything else. I mean it's it's above and beyond what you would normally see as far as just a regular scan yeah for sure, and I mean a tablet: computer would be right and they, if you look at the top, you can see all these all these ports. You know that this would be your scope function, so it is really a full functional scope and a full functional scanner, and maybe I think one of the things we could talk about maybe would be the difference between the two but yeah yeah. You know a scan for the scope. Part would be, you know more of a glorified voltmeter. You know one where you're actually doing measurements of voltage say under the hood, and a scanner would be when you're connecting to the data link connector under the dash. So completely separate tools. You also have like all these fancy attachments here, this wonderful blow molded case and all these little keys here that well, the keys this part would be for the scan soul. So this is the scan tool, part of the tool, and I think really that's where we're going to focus most of these other cables that you see in here would be for the scope and we're not really doing that we're focusing on the scan tool. So this these keys, they call these personality keys and every manufacturer has a different way of doing that. But what these will do is they configure the 16 pin data link connector to communicate and talk on the correct pins for the for the car that you're working on? So this would be something more specific beyond like say, a global scanner for sure yeah. This is this is something that I can really communicate with, maybe 60 different car lines, and not just in a generic format. I can actually read the same information that say a factory scan tool could read, but there there certainly is a lot of hardware here to go with this, and I'm sure you know, like you said this - has lab scope, capabilities beyond just being a regular scan tool. So this this tool here how much? How much would like this, like retail, for I think the retail on the varus - is some somewhere around $ 10,000. That'S really stinking expected, it is, isn't it and I'm gon na get all kinds of crap for even saying that number but hey! I didn't make up the number this. This is through school and that kind of thing for sure. There'S no question about that. I mean the reason I have this tool in front of me. Is my boss owns this tool so yeah? You know, I mean, let's be honest, you know we have 10 of these at Rosedale and uh. You know so maybe a plug for my boss for letting me bring. This is hey. We got 10 of these at our school, so you know well, and this would be something we'd find at. I would say many independent shops because, as you mentioned earlier, you've got those keys that make it specific to manufacture now with this tool, I'm assuming you can do a lot. So, in addition, like I said, the scope capability is about up beyond the scan tool. Part of it, but would you also be able to like say, do ABS, codes and SRS? Would that be based a lot on what you get with these keys here for sure and it's not just switching the keys, you know. Maybe, let's take a newer um. Maybe a newer chrysler, for example, would be the k 25 key. I just know that from from memory, maybe not all of the modules talked on this same k, 25 key. So just what you said, I would switch keys, so I could switch to a different module but basically um what we look for you know from a professional standpoint is I want to be able to communicate with every system on that car? You know that I can to aid in in my diagnosis right and that's that's what would be the difference with professional grade, because this this gets down to the tiny little details, all the little minutiae and things like that mean it might be a power sliding door Or something that you're certainly not going to have any information on with it, with an a global obd2 scan tool, you're not going to read like power sliding door, you know inputs and outputs and codes, and things like that, which is which is why this this tool Is so capable it's not specific to any one manufacturer, it works across many different manufactures and they're constantly updating software and things like that to write this up to date and keep it relevant, and let's be clear to that, you know I get this. A lot, too, is, what's the best scan tool for a particular car. You really can't answer that. I mean really the best scan tool for a car. It would be the factory scan tool right now, you're not going to beat a factory scan tool for what that car can do or what the scan tool can do on that car. The guy that engineered the car is the same group of guys that engineered the scan tool to talk to the car so right right, so it's kind of a no-brainer as far as that goes yeah for sure. But you know in the aftermarket like I you know. I work in the aftermarket I work on 40 different car lines. I need a good Universal tool that can communicate and talk to and give me as much information as possible on these 40 different car lines that I work on. So so, let's just separate that out. Right now, the manufacturer specifically makes their own scan tools for their own software to communicate with their own vehicles and everything that goes along with it correct. So that would be basically to do all end. All. However, if you're out in the world you're working on many different types of vehicles, something like this might be the way to go. Is there something else comparable to this verus? That'S out there? Oh yeah, I'm not sure exactly about the scope, scan tool and laptop combination. You know, I know snap one certainly does they have something: that's called the modus which would be take. The touchscreen take the touchscreen PC out of this and it's just a scope, scan tool combo, it's a little bit cheaper and then there's other manufacturers that are doing similar things. But I'll be honest with you. I don't know names. You know really I'm exclusively snap-on. Well, I see you also have brought its grandfather. Would you say I did did bring the grandfather. This is uh, this one's actually mine and, and you could look out dusty vacations. Well, don't you once you've got this yeah this this sort of becomes obsolete? Well, it does because everything that is in here in the old red brick, which is what this is the MT 2500 I've used - that myself yeah everything that this was able to do is inside of this tool, and you can see I'm pretty outdated here. What am i up to my imports? I'M only up to 2000 and my domestics um Wow 98. I'M ashamed! We don't need to be ashamed. 99 on my domestics. Did you have the grandchild yeah for sure, but this, but this was a tool that also handled Oh BDO and obd one. I remember having all the different connectors in here yeah, we got the same same type of smaller pile of keys, yeah and I got the same. You know data link, connector, and so that would be you know, 16 pin global and then just to give you a comparison, and before the days of internet and downloads yeah, we had like actual cartridges the cards. It'S almost like you know, Sega Genesis yeah. It really is, isn't it yeah? Well, you know I kept this tool for such a long time, because on on older systems, I would still use it, and I still you know, I still may you know say like take an old GM 12-pin, connector and plug into it, and I still AM able To you know, communicate with that system and access information - and you know that's your pre, obd2 or oh, oh, be do as you call it. Nobody, oh oh, be one right, obd once technically california, but well. We won't have to. I didn't know that yeah obd one had certain standards. They said you had to have a check engine light. You have to be able to store codes and look I mean I had a 92 Nissan that didn't even have a check engine light, but it had a mass airflow and all fuel injection. All the other systems, truthfully, not a obd one vehicle obd one was california. So the same Nissan truck in 92. If it had a check engine light, it was obd 1 mm-hmm. Yet they followed the same. Do you know what I mean? They followed the same kind of principles: obd one just had guidelines, so i mean to be specific. That'S why I've always avoided the term obd 1, because truthfully obd ones: california, okay, okay, I do remember Nissan's of that vintage though I think he just looked underneath the passenger seat at the flashing LEDs and ryebeck guarantor, but that wasn't good enough for obd 1. If it was an obd 1 vehicle, it had to have a check engine light on the dash I see, and so that's, where kind of obd ii evolved from that. You know where we had our you know to me and as long as we're on this subject, obd ii came about in 1996 yeah, so it's any vehicles prior to 1996. These scan tools, except for this one here yeah, would not even apply. Although there were a few 94 95 models, it had this g answers. Yeah GM said the only ones I can think of and they weren't really truly obd ii compliant. Yet you know they didn't have all the hardware, but they were like get ready for ders right. Well, I yeah it seemed that GM was was the one that's sort of set the standard as far as the connector and everything as far as that, I can remember yes, I remember before that it was the Wild West not forward. I think that I think I remember seeing a few fours. It had a obd2 connector, but I just remember this is a cord here. Isn'T it now? That'S the multi one! That'S for like Mitsubishi ins, okay, but I just I just remembered there's a Ford. Oh there. It is I just remembered during that time they had several different types of connectors before there was the universal yes obd2, which is what a lot of the cables really in both boxes. I do look at this one. I kept a lot. You know these are all these are all tree obd2 connectors to you know, so I can really still work on the older cars with this newer tool, and I mean ob2, really the standardization was awesome. I don't like the government stepping in and telling me way. Things are either, but this is one of the situations where man it were really because it was Wild West before that, because, as you can see, you had to have all these different connectors right. He had to have all the different software to talk to all those things. It was a lot more difficult back then well before obd2 came along, it was a lot more difficult than it is now so yeah. These standards really did help a great deal. In that sense now, what's beyond obd2, I don't think I can answer that truth. I might have heard of Hobie t3 and I don't even know what what's involved there, but I know what's happening now, is like they're getting rid of this stuff like on the newer. The newer verus, that's the verus Pro or actually all of the snap on line they've gotten rid of the keys and they're using a wireless box that you know you're going to plug this into the data link connector and it has a big box here. They just sit on the dash and then you can just do everything wirelessly. So that's so you can have that sitting in your toolbox. You never have to bring that into the view yeah, although to me that maybe there's not a great selling point, because I'll end up leaving the connector on the car and then the car leaves and now you're screwed for the rest of the day. You know, but still you could lose these keys just as easily that's true. These are the high-end scanners, this this is grandpa and there's there's the grand kid over there. But what I have here is my AK: Tron scanner, that I've used now this. This was something I actually it's. I think it was seekers like a long time ago, but it was an obd2 just basic scanner, and it just it just gave me basic information. But what I like so much about this one is: it actually gave me live data, and that was what was important to me. I wanted to be able to look and see what what the computer was seeing. Particularly the one thing that comes to mind is speed. Sensors, whenever I've got a speed sensor or a speedometer, that's not working on the dash. I would plug this in take it for a drive. If I had a good speed reading on the scanner, I knew that the problem was in the, but if the speed reading on the scanner was freaking out like the speedometer was then I could condemn the speed since a good direction tool for sure yeah. So so that's that's always really using it for to start with now. Recently, I've come across this one, which sort of speaks more to what you were saying about your snap-on scanner, the wireless, the wireless technology and that's what this has. So. This is something that's also quite affordable, that's available to the consumer, and actually I'm going to do a review on this. But I just brought this out to show that that they have come a long way from what they were just a few short years ago and then also what we see there yeah. So why don't we to help round this out? Why don't we go over to a vehicle plug it in look at what the different capabilities are and you know find out what we would be looking for if we were to purchase a scan, okay, cool all right now, we've taken the varus and we've hooked it Up to my o for element, I'm going to need to talk to it. Yep and the whole purpose of this is to basically show what a high-end scan tool is capable of, and then, when you do, your search for whatever tool that you decide to buy. You can say: well, it has these features or doesn't have these features so we'll start with a varus and then we'll plug in my scanner and see what that does and just do a kind of comparison to see how you know what the difference in price actually Means - and you realize we're condensing like a 16 hour class into like a 10 minute video exactly you know all we're doing it. All we're doing is a general overview because it is 16 hours when I do the virus training for my class it's 16 hours. Well, I love that have no doubt you know we don't have that kind. No, we don't well. I think the first thing to point out on this is the main screen would be there's two modes here: there's scanner and then there's obd direct, this obd direct mode. Would be basically what you're getting when you buy an aftermarket global obd to scan tool when you say global? What do you mean when you say that well, global is a obd ii standard that they've they've standardized globally uh the communication protocols and how the car is going to talk to you so, regardless of where the car comes from, if it's being sold here in the United States, it has to meet these certain standards so that obd direct um. We could also call that global obd ii, or also known as generic obd ii. Well, i think, i think, to show maybe the difference between the two, because we're going to do that with your short scan tool to is, i can really show you a difference here and and what we get out of these. These two methods are communications, go for it, I'm just going to the scan, so I have to identify my vehicle connect obd to adapter with the k22 key. So that's that's cool. I got these keys in my hand, tells me which one I need do. I want to load this. Yes, I do, and this is the first thing you'll see that would be different from a obd generic scan tools. You see the different modules that I can talk to on this car, so you can talk to my transmission, my analog brakes, my airbag and my SCS mo. Definitely we see the different modules we can talk to. I would imagine we're going to spend time in the engine, so yeah cuz. Honestly, I think most of your consumer grade scanners would only read the engine and that'd be about it. Alright, lucky to get you get a transmission code, but it wouldn't be able to do anything specific with it. Okay, so we'll click on engine, and then this tells me to use the k24 key, which is going to be my keys here. We use the wrong key. We'Re going to have communication problems so k 24 and from here we have a lot of different things. We can do that. I would imagine we're not going to see on the other cheaper scan tools. You know things like functional tests. You know we can turn components on and off. I can make your cooling fans around your your fuel pump may be on certain cars. I can make your injectors turn on and off generic functions would be my global. You know some of the things that we want to get in. There would be things like freeze frame data. You know, freeze frame data, be you know when a car sets a code, it takes a snapshot of what parameters the car was at when the code set. That'S part of global obd-ii and eight, and we want that information. We can grab it in there. You know, read your codes, clear your codes, things like that right and then the Troubleshooters. You know really I'm not going to go on a rant with a troubleshooter here, but the troubleshooter that snapped one has really to me is what makes the Snapple and tool the best tool for the aftermarket guy that works on 40 different car lines. Like I do, I need help, I don't know all the answers to all of this stuff. So what you're saying is this actually comes with sort of a tutor yeah, so to speak so that when you're working on a vehicle, you might not necessarily be familiar with. Yes, it can walk you through step-by-step the troubleshooting yeah for that particular vehicle or for that particular code that it pulls up yeah, just real quick. I went to one of my garages recently and it was on a Ford Windstar and had all these weird transmission codes, and it was you know, shifting, weird and stalling and crazy stuff. I mean I need a beginning point and I went to the troubleshooter and, and it said that this vehicle is known for the windshield wiper cowl area, to leak water on the engine computer and to pull the computer connector off and see if there's water in there. That'S exactly what I had it was all of the same. You know problems that I had so that's an example of what you might find in the troubleshooter. I mean that allowed me to make money in like two minutes that day when you price snap-on in the competitors in the Austin market. The difference for me is in that troubleshooter and I think that's what makes the additional cost that they that they asked for worth. It no question well absolutely because that saves you time. It also saves you from looking to other sources for that information yeah. So if you had that code like say, for instance, with a consumer-grade, you know scan tool or what have you? Then you would have to go elsewhere for that information, not to say that that information is not readily available on the Internet right, but it's an extra step. You need to take right and whenever you're a technician, particularly working in the field time is money yeah. So any time that you can save you don't even have to leave this driver's seat in order to get that information. So that's really handy to have right there at the push of a button. So that's one that you definitely won't see in a in a generic or aftermarket scan. Sure you know when you're talking to Narracott means that it is universal to all cars. It'S not vehicle specific at all so, and those codes are meant to be precisely that there are manufacturer codes right that are more specific pertaining to specific systems on that vehicle. Right that are above and beyond what you'd normally get by some scan tools. Won'T even read those from what I understand. Yeah, though the p1 codes are, would be the ones a p1, so that first letter is when you see a p1, that's a manufacturer code. When you see a p0, that's a generic global code. So a lot of the global scan tools. You know if I went under generic or if I come out here and go obd direct. The global scan tools will give you it'll, say ah it'll, say: manufacturer, controlled air fuel mixture or some crazy designation for that code. Right or exhilarating mission control fault, you know, and if it's as p2 or p1 there's no there's no data base in the scan tool that defines the code, so they make up this kind of real long. Elaborate like oh, that's a bad code. You know, whereas just a generic here's, the interpretation - I don't know what this code means. So here's this long or something here's something, here's something to make me sound, smart. Yes, that's what it is. You know there's just no definition for it right right. I get it. Ok, yeah, where, when you buy a scan tool, you know one like this you're going to have those P ones: the p2 s whatever you have access to everything and that's why we have these specific keys and everything to go along with these particular makes and models. So that you can get that that information out of that vehicle correct so another piece, I think that would be maybe important to talk about. Not maybe it would be to really show the difference if you're shopping for scan tools would be the amount of data that it gives you. I know that that's unique to different scan tools. Let'S go into into this real, quick and - and let me just talk about a couple of these, so you guys know what terminology I'm using one you'll hear me say: a lot is a data pit and you see these would as a pit, you see the PID Yeah, you see these pieces of information that you're showing up on the screen here: they're known as data pits and the pit stands parameter identification and it's just a piece of information. It'S a data parameter and it gives you a value next to it and and the more data pins we have the better. Wouldn'T you agree. Well, yeah, the more information you have is great, but if you don't know how to interpret it, it's you're just kind of wasting your time and money. I would agree with you, so I think it's really important to say, particularly when we're talking about this professional-grade tool and all this information that it gives you, if you're unable to interpret this information, it's useless to you, it's just as useless as not having this tool. I agree so or not having any tool at all, so, in addition, this is only the stepping off point yeah, in addition to having a tool that can read codes, you have to really think about what you want to get from that tool if you're a professional In a shop working on several different makes and models, this would be perfect if you're at a dealership working on one type of model, well they're going to provide you with their scan tool, which would be the best thing for their vehicles right. So you really have to somewhere find a balance between what is it, the high-end or maybe a tool that will train you when you're using it and - and that's also you know - it's also great - is that this will do that. I won't take you there now but, like I don't know what the CLV CLV percentage data pit is, I don't know what that means, but I can go back to the troubleshooter and go under the. I forget the specific name. I think it's cold. It'S fast track, data scan is what it's called and you can go under that and you can find that CLV and will tell you what that abbreviation is what it does, and so I mean that's kind of a tool that teaches you. You know what I mean so again: you're paying money if you're paying more money for more features, yeah. So usually the more you pay for the tool, the more features you're going to get as a result of the money like you said, usually because we were just talking about that all the exact doesn't always work that doesn't always it doesn't always work that way. You can sometimes spend more money and not get value for that. It'S really difficult to try to figure out value for money, and this is a very difficult question to answer as we're finding here. Yes, because we can start with this and talk about it all day long, but does that help you solve your your search for the perfect scan tool for you right. What you really have to do is sit down and figure out what your capabilities are. What your needs are yes, as far as what you're looking for from the scan tool and work from there. Yes, so as far as brand anything else, all that comes with, basically you being able to read the spec sheet and know what you're looking at when you're searching for that tool. If you can interpret the data - and I like that - you mentioned that - I mean, if you, if you don't know what any of it is, then why are you searching for a scan tool that will give you more data? Well, if you've got the $ 10,000 to spend on this, then it'll teach you yeah. That is true, but not in all circumstances, but for sure, let's compare the two and just to kind of get an eyeball of this list here we have really I'm not going to count these okay, we have a big list. You see that scroll bar that showed up right there, so we have. We got a whole bunch of data pins on this side and we have the same thing over here on this side and I'm just gon na throw a number at you. Maybe it's a hundred 100 hundred or so data pins that we can look at that. Remember where we are. This is a 2004 Honda Element: okay, so I'm gon na I'm going to switch this now and I'm going to change vehicles. So I'm going to exit out of this Honda, and so now it says no active vehicle at the bottom. Go back to my home tab. I'M going to go over you direct now, so this would be more your generic scan tool and go to OBD, diagnose and i'm going to start my communication just asking me if it's 12 or 24 volt no vehicle, specific stuff and notice, we have to pay attention What keys were using? I need a K, 20 key now, all right, so now we're doing more. What what you know, what a global scan tool would do. Nothing, nothing really crazy and I just want to show you the difference in data pits, how many we have between a global scan tool - and you know a factory one and we'll just compare the number of pins that we had available. I think this is something that you would. It would be worth researching if you're going to buy a generic scan tool is what software's in it that will allow me to view as many data pins as possible. I have seen some some cheaper scan tools. You know less than $ 200. That really will give me the same data list that my my factory one will give me, because they have factory information in there just an example. This is it man I have no scroll. This is all the pins I have on this car, so you see the difference right in the amount of data parameters. I can look at here under my global compared to I could under the Honda. Alright, let's go grab your scan tool. Let'S do it that first thing is, I plugged it in and it was powered up already. So that's kind of cool yeah. It is this. This is really designed for the consumer and a lot of well. I don't know this is the one that I have, and this is what I've used for many years and it's it's served my purposes. There have been times where I've wanted more, but at least it could give me some information, so you can read code. You got pending codes, erase codes view data, but like if you scroll down you freeze data and drive Co, monitor Oh buddy, to test onboard systems record data, that's double! It does have a record function, yeah and also one of the things that you can modules present. Yeah, I think that's what it was modules present. Let'S, let's talk about that for a second. If you that's another important feature, I think yeah, I think so too um. If the reason we want to be able to limit data pits, is I always compare it to. I don't know if you, if you don't know if your viewers have either the old Tomb Raider game on PlayStation, one where you would get into a certain room and there'd be all of this stuff going on. You know there there's lava flowing and the walls are moving and you're running, but you're running in super slow motion, because the Refresh of the screen is just not enough and if we can limit the amount of data that we can collect, we can speed up the Process sure so when would that be an advantage? So let's say let's say you have a TPS that has a glitch and you're doing a you know, putting a pedal to the floor and you're looking for a glitch in the signal, you would want to only have the TPS open and have every other data pit Off because that will speed up your your communication and your chance of seeing the glitch on here will be much much higher. So maybe another piece that you know your viewers would want to know would be a tool that allows you to limit the data pits yeah and I use it when I'm checking catalytic converters. I look, I compare the front and rear o2 sensors and have them sitting right next to each other. That way there I don't have to scroll back and forth. I could just look at it and at a glance I'm getting that information, oh and once again we're getting back to your education and your ability to use the tool. It'S it's not so much the tool itself. That'S going to solve the problem for you, you're gon na have to know how to use it in order to be effective with it yeah for so no matter what you decide to get. You need to have some basic information so that you have some idea what you're looking at you can spend $ 10,000 on that other tool and still have no idea what you're looking at and it's completely useless, whereas if you've got some idea of what you're. Looking at you're going to be much more effective and much more able to repair something yeah, I agree hundred percent the kind of well. Let'S take a look at this data this time. I'M surprised that you have this many data parameters available to you yeah, and I think this tool is $ 700 now have you found that to be pretty accurate at the beginning, where it says 106 and there's really honor and six data? I haven't counted them, but I just go in find what I need and that's that I don't I don't do ya know it lied to you because there's no 106 here, that's the bottom of the list right there. I did it so like scrolling up. This is the exact same amount of data that I had in my in my generic. This is ice local stuff, so it's not 106 it just it just gives you the general. This is exactly what you can look for. No, I didn't look at all of them. Exactly but this is, this looks exactly like the parameters that I had it does, but I mean I would suggest anyone if it's for your own car or for a few cars that you work on, that you look into seeing if they offer the manufacturer coverage because Of the difference in the amount of data that you have and the abilities that you'll be able to, but once again, okay, if you don't know how to interpret the data, then that extra information is not going to help you right. What I would say is if this had ABS capability, there's been many times where I wish this could read ABS, yes and then once again, ABS, isn't standardized right like like obd2 is ABS is all over the place, just like anything else, pretty much with different manufacturers. So they're not going to have specific there's two ways like you look at this, though I mean, wouldn't this be one of those things where you would want to have more information than you know what to do with so in case you ever need it. You have it, for example, let's say like your fuel gauge doesn't work properly and the manufacturer offers you a data pit. You can look at the fuel tank level in the scan tool. You might not know what it is originally, but you know, two years later, you now have a fuel gauge problem. Now you're going to go research, it now you're going to go. Do your work on it and guess what you have a data pit that you can now use? Do you know what I mean, so I I think it's always better to have more, but if the goal is to hook up a scan tool and read a code and then change the part off of that code, then go buy the cheapest freakin scan tool that You can find that's it end of debate yeah. That'S that pretty much covers it. You know what I mean right right. Why are we even debating we're going to be if you're going to be hanging, parts buy the cheapest thing you can physically, but if you actually want to interpret the data and use it to do some diagnostic work, you're going to want to one be able to Understand a diagnostic work and two: you want to try to find a tool. That'S going to be able to do that for sure. So, yeah you really you're somewhere in between there yeah, but mostly I say it's going to be the capabilities of the tool. As I said, any scan tool is going to be able to read global right. I think we can agree on that right, but then, as you saw, there's more manufacturer specific information - that's out there as well right. In addition to that, more specific manufacturer information, you might get transmission codes, you might get body codes, you might get ABS codes. The real takeaway here, I think, is: what are you going to use a tool for? Are you going to use a tool to pull parts and to pull codes and replace parts and get the cheapest thing you can get if you're going to use the tool to do some actual diagnostic work, you're going to want as much information as that tool can Possibly give you and if you can get other information go with it like we spoke about earlier, like those common issues that you found on your tool that was able to go out and give you that information. Now I'm going to also say that much of that are well not much of that information. It is difficult to find, but can sometimes be found on the Internet. Well, the Internet has changed things drastic. It has changed things drastically, but it's not. We can YouTube it. We can YouTube it, but it's it's not it's not it's not to do all end. All I mean there's, there's other there's other things to be considered there. It'S not like the video on YouTube is going to specifically deal with the issue that you're having right. It could be similar to that, but then you're still going to have to have some backstory you're still going to have to have some diagnostic ability to take you. There first thing comes my zmapp. You have evap codes, come up a lot. Those are their evaporative emission system, sometimes it's as simple your gas cap, but sometimes you need a tool. That'S capable right of turning those cell anoints on and off to verify their operation right and this tool will not do that right. But there are other tools out there that will so once again you're looking for that capability. If you want to diagnose evap codes and things like that, you're going to need a tool, that's going to be able to go in there the term for your viewers to look for. They call that a bi-directional scan tool. Yes, a bi-directional scan, so that means we can read information and then we can command the the computer. So it's bi-directional so and in some cases you can command the windows to open and close or different different actuators on the vehicle. You can command them on/off. Just simply by pressing a button on the scan tool right this, this is nowhere near capable of that, but it's price level dictates where it's where it fits in that food chain. It'S really a question of what do you need? What do you know and what do you need to know right? Let'S wrap this one up, ok, cool! Well, there certainly is a lot to talk about a lot to think about when purchasing a scan tool, especially after talking to you all the different things here. You'Ve got that we just scratched the surface, we did just scratch the surface and and that's the thing, what everybody whenever somebody asked me that question of Eric, what scan tool should I buy? What should I look for a scan tool? That is a very open-ended question because, as you can see, you can go from everything to just what you need and then somewhere in between there is the type of user you are, and I think I think that's the first thing you need to determine before you Got looking for a scan tool, are you just need to pull codes just to see what that check engine light is on for you, don't trust taking it somewhere. Some places charge like an hour Diagnostics just to pull a code. If you want to do away with that, actually for what you could spend on an hour of Diagnostics, these days, you could have a scan tool that would tell you that so that it could tell you the code, but then you still need more information from that. That that code is just it's just a stepping off point. It'S like I say often that like six different codes for o2 sensors, and only two of them mean that the o2 sensor is faulty the rest of it means something else. So you, you have to know what you're looking at number one and number two. You have to be realistic about what your expectations are. So if, if say, for instance, you're opening up your own independent shop or maybe you're a technician looking to have a scan tool on the side, for maybe your side work or something like that, so you will be working on more than one type of vehicle. You want to try to go up the food chain so to speak, and you want to look for something that might have abs capability or transmission capability or bidirectional. Was that word, and so I would say that if you are that type of person, I would be looking for something bi-directional as opposed to what we have here, which is just a one-way street. What is a map? I mean we look at a scan tool like just to reiterate what you were saying. We we view a scan tool as a as a map, and you have a compass and you're trying to find some direction, and so I always teach that the scan tool is your map and your compass, you know it doesn't it doesn't need to be up. You still need to walk there. You need to be able to read the map and follow the compass and go the right direction and the scan tool. Can you know in the wrong direction if you're, if your knowledge, isn't there all right right, that's a fantastic analogy. Actually, because that's what it is, it's a journey Diagnostics is a journey. It'S it's it's a way of getting from point A to point B. You'Ve got that little yellow light that comes on in your dash to the point where it actually gets fixed. Well, yeah. That is, that can be most certainly a journey. There are many times well will freely admit it could be as simple as replacing a faulty part, but then there's also issues with wiring issues, with connectors issues with computers and all types of other things that can go wrong, that the computer interprets as a problem because Computers speak in a language of voltage and the voltage is either here or there and if they don't see the correct voltage, that's when that little yellow light comes, and it says I don't see what I'm supposed to see here and there you go so they speak In the language of voltage as well, so you need you need a tool. That'S able to speak yeah to give you that compass to give you that map, but as far as what you actually need sit down and really think about that. First and then look at the spec sheet on the on the tool that you're considering and that should get you the rest of the way. I would think I think it's good, I think you know maybe to follow it to is, is to educate yourself, which is a lot of your viewers, are already doing get each other using each other and you're gathering information, you're sharing that information, and we need help. You know that's what we do so you know you have something you're. Looking at you're on tour of you, you go online in you, yeah as it in and research it yourself and educate yourself, absolutely and don't be afraid of ignorance, because we're all ignorant to some degree and reaching out for help and asking for help is not a Bad thing, looking for a sign, eat, help all the time. So do I the time? That'S why I have him here, but but yeah I think you get the general just in a general takeaway of it. So to answer your question figure out what it is, you need the tool for and then work towards that look at the spec sheet and look at what that tool has to offer that you're considering and see if it meets those needs. So I hope that answers your question. We took all this time to try and slice it. It'S a tough cut. He took all this time to try to answer it and we still don't feel like we've but scratched the surface yeah. So that's the best. We can do for now. Anyway, I am pair at the car guy and if you have automotive questions, I would ask that you head over to eric the car guy comm. Why? Why? Because it's the most awesome place ever to get answers to your automotive questions? That'S why you go there. Welcome video to tell you about all the wonderful features we have it, eric the car guy calm to help you with those automotive issues, and if you wish to connect to me socially, i can be found on Google Plus Facebook and Twitter. This guy can be found on the channel scanner Danner. He cannot. He also has a book which I want to put a link to in the description. Yes, she does have a book. You took the time to write it dude and actually I've read it. It'S quite good. I'Ve learned quite a bit myself, so if you're on that level - and you want to learn more about the back story behind those and how to interpret them in that type of thing, that's I would advise this. I would advise checking it out. So thanks Eric and thank you very much. Let'S not forget we got to close this out. Yeah yeah be safe, have fun stay dirty, stay dirty I'll, see you next time, all right, cool,

Recycling Automotive Paint








Welcome back before I get started, turning the paint chips, just a couple of things. First of all, I finally made it through all the Christmas ornament challenge. Videos. Thank you so much and really appreciate everybody that entered Ellen and I should have a worked out, probably announce the winners, maybe this week or early next week. So again, thank you so much and if you haven't seen Tim's ways, a video I'll put a link down below in the description, you should go check it out so great job Vance and way to stick with it. Alright, a couple of things about the paint before we get started, so this is it's automotive paint, it's overspray that would build up on the racks in the factory. This came out of a Freightliner Freightliner factory here in Portland Oregon, so almost 99 % of the stuff. I have is our little teeny pieces like this - maybe three-quarters of an inch tall the to do a box like this. I maybe have five or six pieces left this size big enough to do that. So most of it is just a little stuff, so I can do you know little finials or things like that or little I'm just in little inlay pieces. So it's not. I get asked to do chess pieces all the time from the other video, but I don't don't have anything big enough other than these little guys here a couple other things I wear my respirator hood when I'm doing it and the reason I don't turn on my



My dust collector is first of all clog it up in about 30 seconds, but the other reason is, I save all the shavings and then I cast them in aluminum to make other things like: pin, pin blanks and things like that. So that's why I don't use that my dust collector has a great over the front of it, so clog up almost instantly, but you need to wear something it's the fumes from it. I wet sand. So I don't have to really really worry about that, but just turning it there's an odor. You know that it releases and it's I'm sure it's not good. So keep that in mind. If you have any so I sold some over the weekend to someone Turner. So I will just keep that in mind guys when you're turning it. So it's I've only turned a little bit of acrylic and the stuff.


I'Ve turned isn't like this: it doesn't. This stuff tends to chip. I turn it from from the face going in, try and go slow. I don't try, don't heat it up. It gets a little mushy. If you, you know, try and write your bevel or something on it. So I will give you some, hopefully give you some tips and don't be afraid to if you can't quite get the shape you're, you know with the chisel, it stands with hundred grit and it sounds actually pretty fast. So if you want to want to do some, some shapes with it, in fact, like all the jewelry pieces I have up on Etsy, it would just say it Robin just sanded it with hundred grit to shape it and do things like that. So it sounds pretty fast with hundred grit, but just keep that in mind the fumes. Alright, let's go ahead and get started and all I will. I have a little bit of footage from the box. I put that up on Facebook and everybody seemed to like it had already sold, so I will I'll try and get a couple more up pieces and I'll get some more boxes up on Etsy with the painting layin in them. But that's, I think, that's about it. Let'S go ahead and get started. The wood shop is sponsored by robust length, easy wood tools and chef work. It'S okay! I just glued it onto a waste block here with hot glue and that's what I always do to turn it. So here are the two tools that I'm almost always used to turn. It is either round carbide cutter or a very fine spindle gouge, this one, the cutting edge on it is right there. It'S maybe eighth of an inch, and this is the one from Cindy draws to its. You don't want to use your regular spindle gouge or like a bowl gouge or something where the bevel goes all the way down. If you get it hot it'll start to get a little gushy, so you don't want to don't want to heat it up. I usually, if I'm cutting with this one, take a few passes with it and just let us let it spin for a minute and cool down and then keep going at it. You don't want to don't want to heat it up so, and you always want to turn right into the end of the headstock faceplate, like that. You don't want to come out here because the layers, if it catches one of those it'll peel it back so everyone's will come around to do some little thing and then ruin a piece, but it's for most part. I try and stay stay going in. So I'm just going to go ahead and try and shape it. They give it its basic little shape, I'm just going to make a little dome something I can insert into a box on this one and then we'll make a finial with the next one. But I'll show you how it works. I turn the lace beat up all the way to 2000 the faster it's going, the less chance of a kitchen on one of those little layers. Is you hear that little pop take a look and didn't really do anything, but that's what what happens is it'll grab a layer of it, their God and it took a big old chunk out of it. That'S what I mean. So it's kind of you start out with a piece like this and you end up with a much smaller piece, but it weren't that when they come out some lower this time just a little bit all right. That looks good and just come around here, flatten that off, so I can inlay that into something just going to use the fine spindle gouge for that. Okay, I'm going to go ahead and sand. It now and I turn the lathe speed way down. I have some water here and I'm out of the out of the mesh pads, but if I had those that runs run through those two, but the the ultra gloss seems to be working pretty well, so I just just wet sand it, so it doesn't get too Hot a lot of times too, if you're trying to do something little delicate on them, it's probably easier to sand it. If you just do it with a hundred grit, it will eat away at a pretty fast.



I'M just going to finish running through the rest of the grits and I'll, be back and show you how I put the polish on just put a little dab of the crystal or ultra gloss on turn. The lathe speed down to low I've have the splatter all over the place, you'll notice to it. It takes off some of the color because it's well sand in a little bit that turning the speed up slowly, there we go and it puts a nice little shine on it. So alright, I'm going to go ahead and cut this off and I'm just going to cut off with the hands on I'm just going to use this as the an inlay for the top box lid or something okay same thing, just glued it on use the tailstock To put some pressure on until the glue set up and go ahead and start shaping the outside, we'll make this one a little more more delicate this it seems to be doing alright, but just taking nice light little cuts as you go down, try not to try. Not to force it, I'm going to go ahead and use the spindle gouge now and come in here make a little handle all right. So hopefully you can see that I just made a cove there and they made this little spot right down here so that I can sink that into the top of a box or something all right.



I'M going to come in just a little bit more right there and we're getting pretty close to glue. I'M just gon na I'm going to let that be and I'm going to go ahead and sand it and it will do the same thing. But I'm going to clean up some of the shavings. First, I'm just going to run through all the grits again during the Lay's bead down, then I'll be back. The wall put the polish on it I'll be able to use that for a pull on a box. You all right, I hope that helped so, if you're getting ready turn some of this just keep in mind just light light. Little cuts try not to heat it up too much and most important thing is wear some sort of respirator with it, because it is automotive paint all right. I think that is about it. If this is your first time here, I have a new project video every Friday. I hope to see you there and if you haven't done so yet, please subscribe take care. You

Automotive Industry Jobs on the Rise






Hi, I'm Lauren fix the car coach if you're looking for a new job or a career path, change consider the automotive technology field. There is plenty of jobs, not just as a technician, but in sales service and parts. Parents and students should take a second look at automotive repair, a high-tech career that is always in demand and can't be outsourced to overseas parents if becoming an automotive technician is not high on your list of career choices for your child. Perhaps it's time to look again. You may consider the automotive industry for yourself as well. The auto industry is continuing to grow at a very high pace and with more units in operation. That means that we're going to have more customers that are going to be coming through our service department, given the advance of Technology and a richly varied industry that offers an array of positions and career paths. The future is bright for talented young persons with math science, communications and technical skills, and, unlike many high-tech careers that require four six or eight years of college automotive technology careers can begin in just two years of education. As for any career, lifelong learning and continuing education is necessary, but the simple fact is: students in automotive technology can get out in the real world sooner with less college debt. Moreover, job growth looks strong in the foreseeable future. The US Department of Labor's Bureau of Labor Statistics forecasts, automotive, repair and maintenance industry is expected to add 237 500 new jobs and have a 30 percent growth rate through 2020. Qualifications are a great frame of mind like to work with people because we're in a people, business, and I think that if they have the willingness to learn, we will give them the tools and teach them the road to becoming salesperson technician. And whatever else we have in the business, so if your child prefers to get out of the real world and make his or her mark consider a career in automotive technology, more than three hundred and sixty thousand professionals hold current ASE certifications for more information.

How do you start a career in automotive engineering?






With the engineering came from, I used to expect across as a teenager, so that was sort of my enthusiasm to get into engineering. You know steel weights were coming by. I had a had a project car. I had an old Volkswagen Golf, so you know it was those kind of skills. I was learning back visit back to the teenager. I made choices available for different subjects, so I'm having to go in slightly and spidery. I'Ve got support from the academic staff. Helping me to follow my dream, even though I'm not quite on the right degree, it is an exciting environment. I think we've got a duty to convey that message to the user, so they can see what it's all about. You know - and it's not just in my if you go to places like Jaguar Land Rover, not Toyota, the other, very clean, modern factories, lots of exciting things going on, but to get engineers. You know it's just successfully be employed in those companies yeah. They have to have the right skills, and that starts right at the very formative ages. For me, I thought often go-kart racing when I was a teenager, so be able to take on the engineering and the maths in my physics at school and actually developed that into a vocational subject. That'S why I chose engineering. The former student competition was actually a really big influence for me and I was looking to do engineering anyway, because I'd studied it at GCSE level and I was originally interested in the automotive course. I since changed my degree to a mechanical engineering degree. To give me a bit more of a broad understanding of engineering - and I didn't understand exactly where I wanted to work five years ago. So I'm definitely Dora gret changing because the a mensch cause has been fantastic in Samael and for what I say is quite few say they and it's a really good learning curve for all of us. Some of the team, you know, had no hands-on experience. So for them you know designing a building. The car is fantastic. Well, Williams have a fun place in my heart because that's where I spent a year getting trained up and I can directly see how the lessons I learned from the sort of senior managers there has translated into stuff, I can do with the formula student car. I actually start with Bentley Motors in a month's time, so I'm more going the automotive REM kind of route than the than the motorsport Formula One. When I'm going to be replacing the piece, a DS, high performance powertrains in September and so much of doing a procurement role which allows me to get the technical side and work alongside engineers, but then use the management skills that I've got from my degree. So yeah. I'M looking to work at Bentley next year, I've already secured a job there, so that's gon na be really interesting to get there and see how everything works. [, Music, ], you

Top Ten Colleges For Automotive Engineering





Clemson University by itself, the Clemson University international center automotive research cui ciear would make Clemson a contender for this list. In addition, the south carolina school has a strong vehicle dynamics program and is located within 160 miles of almost every NASCAR shop. California, Polytechnic State University, San, Luis Obispo and California, Polytechnic State University, Pomona, Cal, Poly, San Luis Obispo and Cal Poly Pomona also have programs that are worthy of consideration. The former's College of Engineering has produced a winning supermileage team. The latter has placed in the prestigious Formula SAE collegiate design series Cornell University. The Ithaca New York institution is not a traditional automotive school, but any university that has eight FSA II championships to its credit, has to be on this list. In addition, Cornell is one of the few colleges to enter both the automotive x prize competition in the DARPA driverless vehicle event, Georgia Institute of Technology based in the middle of booming Atlanta, Georgia. Tech has long been an automotive powerhouse with a strong, F SAE team. In addition, it has a respected design school, not in significantly its mascot is a 1930 Ford Model. A sports coupe Indiana University Perdue has long produced top engineers for Detroit and its suppliers. I up UI boasts a Motorsports engineering program, Ryan Newman, one of the very few NASCAR drivers who graduated from college holds an engineering degree from Purdue Kettering University having fewer than 3,000 students. Kettering University produces far more than its share of industry personnel located in Flint Michigan. The school formerly known as General Motors Institute offers degrees in management as well as engineering University of california-davis to pick from among Cal Davis, Cal, Berkeley, Stanford and Caltech, as all have programs that seek to find the future of personal transportation. Most enter more than one of the touchstone competitions, however, our experts said Cal Davis, students typically possessed more practical experience, University of Michigan or Michigan State University, whether Michigan, Michigan, State or Michigan Tech will produce the best automotive engineers in the future. Alumni from all three can be found at most automotive related companies. Potential students will have to decide which best fits their needs, but any of these three have to be considered a top choice: University of Texas at Austin University of Texas at Arlington and Texas, A

Automotive Memory Saver





This video by Richmond today we're working on problems that happen when you remove your automotive battery. Now, when you do that, what happens? Is you lose the memory in your radio, the memory in your computer and if you get a Cadillac you, you lose the memory of the the seats where the seats position themselves. There'S a lot of different things that removing the battery can delete the memory of so today we're going to show you a solution for that now there are lots of tools out there that you can use to cure this problem. All you've seen the ones where you are, the nine volt battery plugs into a cigarette adapter, and you plug it in, and you can use that when we're going to make our own out of a old cigarette adapter and a transformer, they can go from nine or Twelve volts this would happen to be a naive old one and then we're going to need some diodes. I'Ve got some diodes left over from the horn conversion kit that I did. This is all electronics pot, number gi8, five one, let's say a 300 volt diode and those are all the pots we need now. The first thing we're going to do is take this transformer here and we don't need this end on there and we'll just cut that off now. How do you transform you'll see on the wire there's two wires and one of them has a slit in it as a color on it to me, that is the positive wire. You know this one. We have the same thing. We have a colored wire, that's the positive wire, so those wires are going to match up color for color. Now, we've taken the insulation off of the end of the cigarette adapter here, and this is the wire on the transformer and you can see that we staggered it a little bit and now we're going to twist in our diode. Now remember, the diode goes into the positive wire that would be the wire with the coating on it. This particular case there's a white coating now on the diode. There is a band. Now we need the band facing the current flow, so that would be towards the cigarette adapter, so we just need to twist it on the end of a diode here, we're going to end up doing is we're going to solder these together. Of course, there we go now we're going to start those right now it will sort of that wire go yeah, yeah we'll do the other one. Alright. Now we can solder our other wire this one's a little dirty there we go. Okay, there's our! Why is all taped up and we made sure that the diode didn't hit the ground connection there? I take that one first and then real tape all over the diode. So, let's give it a shot now before you do this, make sure that you know if your outlet is live or not. Some imports, I believe, are only on when the key is run so you'd have to have the key on to do that. This one right here is hot all the time so we'll take the cigarette lighter out and we'll plug in our transformer and just to be on the safe side. What we're going to do is we're going to test it with the meter see if we're good to go here, all right. We got voltage so, let's plug it in all right now, I'm going to disconnect the battery I'm going to just disconnect the negative side of the battery okay battery's off now we're going to put the battery back on okay, it's just a simulation! If you are changing the battery, of course, to be more time, but that wouldn't matter now that should have kept the juice in the the radio settings and everything should be okay, let's turn the key to accessory. Now, if it didn't work, the radio will be all staticky, because we won't have any channels in there, but it should be okay, look at that. It works it saved that memory and that one was only a nine volt transformer on that. It'S saved uh save that memory now just to be on the safe side. What we're going to do is a computer scan and see if our I am monitors are still intact there. They are all the IM. Monitors are intact if they weren't they'd, be grayed out on the scan tool and which would mean that we would have lost our memory in the computer, so we're all set, and that's all there is to making an automotive memory. Saver.

Automotive Service











Your life works not so many years ago, the automobile was considered a luxury about the only time it received an airing was on Sunday or a holiday. Today, millions of buses, trucks, and cars travel the highways from coast to coast. The number of cars on our city streets offers proof that for millions of people, automotive transportation is almost as much a necessity as a house. The good all-round serviceman is really for mechanics and one. He must be able to make all repairs in the engine such as repairing or replacing the camshaft. He must understand all types of engines thoroughly all, although all gas engines are fundamentally the same.



Differences have been developed in the various makes of cars which the mechanic must know, for example, in cleaning out carbon and grinding valves. He may work on the l-head type engine one time while the next engine may be the overhead valve type. Both types provide efficient power, but the problems of adjusting them are totally different. A good serviceman is also a machinist in an emergency. He may be called upon to make completely some minor part which may not be in the stock of repair parts. The superior serviceman is a welder through accidents and even ordinary usage parts are broken and have to be repaired. The expert welder is valuable to any garage and often concentrates on specialized work at very good pay. In addition, the all-round serviceman is an electrician and must have the knowledge and skills to keep the automobiles electrical system in working order. But without the spark to fire the engine, there would be no power. In the early days, electrical energy was supplied by dry batteries, but the car of today carries its own generating and storage plant. The storage battery is of low voltage, so a coil and condenser is necessary to step up the current enough to jump. The spark in the spark flood, the callin distributor, also must be tested and kept in proper working order. Besides the ignition system there are, the lighting and starting circuits would sometimes need the services of a competent mechanic. The use of heaters, windshield wipers and radios has further increased and complicated the electrical work of the service man because of the high speed at which vehicles travel today, the care and adjustment of brakes is a serious and vital part of the service man's work. The safety of the car on the highway largely depends on good brakes, along with correct and accurate alignment of the wheels radiator, repair and general care of the cooling system is important and making cars run efficiently and economically. So soldering is another of the many kinds of work the service man must do in the larger garages. The man who becomes expert and servicing engines may find specialized work on engines only. There are body and fender shops which employ men who are specialists in that line. There are battery and electrical shops and other shops which make brake testing and wheel aligning the principal part of their business, for any of these jobs are thorough, training and general service work is valuable. There is an opportunity in the larger garages for the service man to advance, to service manager or to become a troubleshooter. Besides technical knowledge and skill, these jobs require the ability to meet the public, to make a good impression and to explain clearly the work that needs to be done, or that has been done. Some servicemen become automobile salesmen if they have sales ability, they are usually successful because they have the advantage of really understanding the cars they sell. If you enter the automotive service field, your first job will probably be as a helper in the shop of a general service garage or it may be in the parts department. You will have a chance to learn the names of the many parts of an automobile and their relationship to each other. You will learn about new vacations and other operations in automobile upkeep.



While doing these jobs. You must be alert to learn everything you possibly can. You must also study constantly in your spare time as a basis for study. There are numerous service manuals put out by the automobile manufacturers to help train servicemen to do their work correctly. These manuals are full of accurate information and they're interesting to study because of their detailed diagrams and illustrations. There are many good books on automotive service in your school or public library be sure to select books which are up to date. However, as automobiles are constantly being improved, most automobile manufacturers provide training courses for their service men. Regular training conferences are held for employees in the more up-to-date garages, the manager, shop, foreman or some other expert discusses the newest automobile developments and how to service them properly. Movies and slide films are sometimes shown in the local shop. Manuals for further study are provided along with the films. You should never miss such opportunities to learn if you expect to become a successful mechanic. Another way to learn while working is to attend evening classes dealing with the fundamental principles of the automobile. These classes are conducted in the larger towns and cities by the public, schools or other local organizations, and some of them courses in shop practice are also given. Don'T fail to take advantage of these courses to help you prepare yourself for the better jobs. There are a number of private automotive trade schools which offer good courses, but some of them have practical equipment such as this cutaway duplicate of a differential.
