In this video I have a look at a customers GMC Yukon Denali with the big 6.2 that was towed in for a no start not crank. I have seen this enough times it's just as easy to take a guess rather than busting out the tools. Not to mention we already did a video on one of these.
-Enjoy!
UPDATE: Customer had me bypass the connector and throw away the module and the battery light went out after tightening up the positive terminal. I just had it resting on there when I went out in the lot to bring it in. Now he can go get a sticker on it and get it on the road 🙄

That folks got us in 2007. It's a GMC it's a Yukon that's the Denali I Assume it's a 5-3 and there could be wrong. Uh, it doesn't run, doesn't crank, it doesn't do anything, and it's got an inspection that's a couple years overdue and it's not even registered on the road. Uh, the guy made the appointment.
There may be a lack of communication on my part. Um, but what I was told is that he put an oil pump in it and since then, uh, it's had electrical trouble and it's stuck in second gear. That's basically all the notes that I have on it when he made the appointment. um, tried calling him to see if this is a new symptom.
I See there's no parental display on the dash was there's a Prindles there, but there's no line under what gear it's in and again, it doesn't crank. it doesn't do anything. Uh, it was out my parking lot. the battery was unhooked I hooked the battery up.
battery seems to have a charge on it. You know you can move the shifter in and out. windows go up and down. horn honks that kind of stuff.
but that's it. so that's all I know. so let's get after it. Give me an idea here.
I come in to hook up the alltail figure I might better show you. um so key on engine off. We do have an engine light which is good. no Prindle display like I say I don't know if we got a I don't see a backup camera.
service, suspension system put open. what else was there? Park assist off but yeah, when I go to try to start it, nothing happens there. Pretty neutral. Nothing happened there like I said yeah we got a horn.
we've got headlights. you know? seems like we have everything like that. You know, power windows go up and down so no clicking? No nothing. what's up Miss though I got you a package.
Perishable, huh? All right. Well thank you I'm trying to let it Auto ID it's not happening. So we're going to type in the VIN number uh manually which this tells us basically that there is. you know, no, it's going to be a no communication situation.
Yeah there we go. Disadvent scan failed which I need so this is a 6.2 I should know him being at was the denial version. Uh so just my big fat guess going into it is the suspension control module is rotted out in the back. that's my big fat guess.
Um so anyways, let's figure it out the right way. So I'm going to let it go through a system scan here. I Think what we'll find is everything on the high speed data Network here is not going to function as we can see it's all grayed out but everything that runs off the class 2 or the low speed here I think it's class two on this is likely going to function and be tattletailing and they can't see. you know stuff on the high speed.
Network So we'll let that finish and then let you guys see what we see. It's all done we're going to go. to report: Skip that uh supplementary passenger presence module erratic loss come with radio past your presence high voltage, low voltage invariable serial data receives that's probably an airbag light on for a while I'm guessing uh, driver's doors problems lost kind of with HVAC All right, Well, we're just going to make note of these. Nothing really to worry about. A lot of history codes and stuff in here. Those are all history codes like I Say with the battery being unhooked, probably had lots of dead batteries and yeah, because these are all past past all history codes. All right, let's focus on the fact that we have a no com with anything on the high speed. Network I think uh, probably pattern failures and experience is going to help us with this one.
Pop right in here. Pin 6 and 14 is what we want to look at for our high speed can and we can see we have nothing. It's at one and a half volts and just kind of chilling there. I'm on pin 14.
and that's at about I don't know. three quarters of a volt I would guess yeah, about 700 millivolts and then back on pin six and that one's sitting at 1.5 volts. Um, the low speed I Don't know what it is if it's pin two or pin seven I might we might have to look this up. thank you but that that one is talking anyways.
You know what is the J1850 Is that Pin two? No, it's not blinking. There we go. There's Pin One. Okay, so pin one's flashing at us all right and there's where we're communicating on our our low speed Network Um, so just in case you wanted to see that so there is com there.
But when we look at our our regular high speed on pin 6 and 14, nothing's happening. Uh like I say I've seen this enough on these Chevys to know that usually it's just a module that's gone Haywire on us and on the Denalis and the Escalades and stuff. it's typically the suspension module sometimes but not always I Think we did another one of these videos on a Yukon and I don't recall I don't remember what we finally looked back in the video. remember it's a maroon Yukon around the same era I Want to say that I always probably suspension module on that one too.
So let's um, before we dive too deep into this, let's just raise it up in the air, give this thing a visual inspection. It looks super rotted from up here and like say if it's been sitting a couple years. Boy that can that can add 10 years to a car Pretty quick. Welcome to New York baby, that's where your friend belongs.
Lady, this thing smoked. unless you ride it boy, gas lines and everything are ready to explode. She is rough. Front brakes are solid.
Rust looks like it got oil sprayed at some point in its life. But wait, can't hardly turn these wheels. She's rough. man.
cross members are running out of there. Thank you. There's our suspension control module. What's left of it? I Just slapped.
Uh, Pin Six here. Pulled up on our scope so we can see if only unplug this if our Network comes back to life. Nice part Bob. He's being all rocking out because uh, the module comes out nice and easy. Nice and easy. It's got one rat hole through it, so that's usually a pretty tall tale sign. Looks like somebody's been here before though. Hot damn it broke.
Oh listen, bing bing bing. Oh, the whole connector fell apart. Oh yeah, somebody's got this thing jammed rightful. Dielectric Grease and stuff.
Of course. that's what we do. Bingo, Bingo, there's Pin Six. There's Pin 14.
we'll take and get a little more time on your screen here. All right, so we can see we have some data network communications restored. uh, without even looking a wiring diagram. I Do know that up here somewheres I'm as hard as usually is the other half of the resistor that's taped to the harness.
but the truck should probably still start and run without it. I'm just I'm Gonna Pop That connector apart and put this back together just in case we end up leaving this unplugged. Sometimes it's easier to fix a car with experience than it is actually looking. Of course, nobody really learns anything from this, but yeah, boy, they really got that thing.
Patrick Full of grease. Maybe they were trying to fix another problem probably the service suspension light that was coming on and off intermittently would be my guess. I'm pretty sure it wasn't that long ago that we actually did a video on one of these. Nobody ever fixes these.
Oh actually, well, this is where your compressor goes ladies. So yeah, so never mind. so nobody's fixing this one. I was gonna say the compressor is usually routed out and I don't know if we ever put up that video.
We did one of these where I think I mentioned in the video that it was the first time in all self-made Auto history. So we actually fixed the air suspension on one of these vehicles. Typically when these things come to me, they're they're done. It's smoked.
You know? it's like this one frame trotted. It's not worth doing anything with junk. and I think the one that we did in that video I think we just cut the network wires hooked them together. but uh, Anyhow, that was about this.
How about we exit out of here? Oops. Oh oh gosh, come on. Chase Let's go back to our Diagnostics or history and this is the work done. I think it's 07.
it should be able to talk to the high speed now even though that resistor is still unhooked in the back. Let's just go fault scan see if we have communications. Yep, we do. So now our our ECM is back online.
Tcm's back online I've got to wait till I hear from the customer to see what he wants to do. I mean obviously there's no sense in putting this in or you know, getting a new one because the compressor is missing and then there's really no sense in fixing this truck because it's completely rotted out, frame smoked, everything on its junk. But at least I don't have to pull it back outside with a lawnmower. I Guess Well it was littered right, full of no com codes and all kinds of codes in there. Let's just take him for Grins and Giggles just start it, see if it's got its gears and then that. I've just gotta wait for the guy to call back. All right, we've got our printable display. These six twos are so awesome.
All right. Service suspension system of course we got reavers. hey. ABS Works Battery lights, Huh? Foreign? all right.
Beautiful. It doesn't seem to be stuck in second gear as he was mentioning. All right, Yeah! I Made a shift at least all the way up to Fourth There sounds like there's some Rust flying out of the back stop I Guess that's it. I'm not going to go any further with it.
It's obviously not charging, so wait to hear from this fella. It's kind of a short silly video folks, but it just goes to show that sometimes diagnosing stuff I guess if you will diagnosing we use that term lightly here or guessing at what a problem is can be helpful if you are familiar with some pattern failures of a particular brand or symptom. or you know, however you want to use the word there that I'm not using right? The fact of the matter is, this is probably the eighth or tenth one of these that I've seen come in with the same symptom and the same exact problem. So something like this is pretty easy.
Now if this had a spare tire in it and it was, you know, not a New York car and it wasn't all rotted out, we would approach this a lot different. but being that we'd seen under the hood like oh, this thing looks pretty rotted under the hood it's going to be smoked underneath which we saw, you know, the frames, rotted cross members Rod brakes, gas lines. that's that's junk cars junk So then we could go right for that thing. takes a you know a minute.
you guys seem to unplug it and see if we're right. If it wasn't then we're going to stop right there and do our our diagnosis like we should. Uh, you know the proper way. but sometimes pattern failures really help you and help you not waste a lot of time.
Uh, nothing more really saying this. I'm gonna wait till I hear from the guy I assume he's just gonna have us cut the wires Loop them together and you know Adios Muchacho! And I just sent them down the road but I don't know what he's going to do with the truck. probably have to get a look and stick them somewheres somewhere other in my shop. I'll tell you that and then I don't know if he's gonna drive it, but like I say with all the brake lines, gas lines, stuff ready to blow, it's just going to be an endless you know? Money Pit Not to mention the frames are added so that's it.
Comment Section: folks, questions, comments, concerns, see and see the Facebook you know where rat folks. Not a tick tock though jerk and just remember viewers. If I can do it, you can do it. Thanks for watching foreign.
if anyones looking for a good muscle engine this is it
part this one out and recoup your loss and make a hunter gatherer buyers day
yea the module came out nice and easy
surprised it was not hanging loose dragging the ground with dog bite marks on it
how do you know you are in old york
rust
you aint in kansas no more dorothy

Hack
How much crap will consumers take before automakers go back to simple vehicles. Old school Throttle bodies and no options
What makes a car won't start but on the third try it will crank
Sell the engine and junk the rest. Those 6.2 bring a nice chunk of change
SALT MAIN AUTO!
If the car's already disassembling itself you don't have to disassemble much. Genius
To me engineers are some retarded knuckleheads why would you put an electronic component at the lowest point under a vehicle so it can soak in water that you’re driving through
Another awesome video, just blows me away seeing the amount of rot in these newish vehicles. Never see that here in NZ , mind you we dont have salt on the roads either haha. Such a shame.
I was having the same problem with my Escalade so I pulled that module and all is fine now. I didnt cut and splice those wires though but it's been driving and acting just fine for months now. Anybody know what happens if you dont do the bypass wire splice thing?
I have to say that Pacifica, California may be the Emperor of Rust. I saw a car there with a hole rusted THROUGH the roof. That brine spray off the beach does a number.
Past experience is really important I like the fact that Eric verified his diagnosis as he always does.
My opinion on the
Frame and body rot is the public needs to be aware That you need to take care of your cars frame, and body when you’re in any states where there is snow and salt is used on the roads.
2012 Sonic LTZ 1.8l hatch, I got traction control, steering system, check engine light and get the same response when turning the key. No codes and I'm up in the PNW so, no corrosion worth mentioning. Any modules or experience with common causes on the sonic? I've cleaned grounds 100-400, all battery wire connectors, starter, alternator. when I reattach the battery, the car makes a single long chime tone and then looses its mind and sounds like a classic bicycle dinger. drains battery down to around 6.3v and I'm trying to get a new one soon.. Is it just a combination of bad brush connection on starter, bad/minimal ground and battery connection, loose terminal on FPCM/TCM connectors and a bad battery slowly overworking itself? Appreciate any thoughts, before I go crazy and DIY battery wires and my harness out of speaker wire and cut up jumper cables. lol
I enjoy your U Tube channel. I recently subscribed and wanted to communicate. I am new to this so bare with me. I want to ask if you have any experience with BG products. I have an 89 Cadillac Brougham with a 5.0 Y motor and an oil cosumption problem, started out 1 qt at 50 mi. Using various engine flushing products and frequent oil changes l have gotten it up to 1 gt for every 300 mi. Minimal oil leaks, new valve seals and some highway driving is how l got to this point. Do you have any experience with the BG motor flush treatment?
Refreshing to watch a true technician, instead of dealership parts replacing monkeys.
Again great hands on with experience.
As a dealership tech you need those pattern failures to make up for time lost on other job .
Absolutely agree, experience has been my first option in diags
What autel model scan tool do you use in the video
Trying to keep up but lord it’s hard to – keep ‘em coming Eric! 😂😂.
Not worth fixing
Why are manufacturers not required to add some type of bullet proof coating to the frames from day one? It’s ridiculous how quickly that steel can rust through like that. Motor and trans still does its job but rust ends up raping your pocket pretty darn fast.
I will never live in a state that uses salt on the road.
This wasn’t a guess. It was a hypothesis based on a diagnostic mind with a wealth of experience
Great educated guess
That’s a beautiful donor truck! I’m looking for something similar for my 85 k10.
In SW AZ, we’re lost when it comes to rust. We just listen to SMA and follow his lead. He’s the “King of the Crusties” 😅
I really enjoyed this video. It was great to see how your experience led you straight to the problem. Could you possibly elaborate on how you did the bypass on the wires to the connector allowing you to scrap the module? Thanks again.
When trouble shooting any electrical problem, an electrician told me to start at the source, in this case: the battery.
I don't think it's silly because like you said, time saved. And that means you can start it and that's a big life saver for many.
I basically just roll from one lucky guess to the next 😂
I feel sad about any vehicle from the Rust belt. Not worth buying, not worth fixing. A mortal disease.
Prindal display, never heard that phrase before.
Even though it's a short video and I'd probably never see this issue, it's something I will have in the memory bank now.
I think he called me a jerk lol. A couple of videos ago I commented if he was on tic tok… I even said I did it to piss him off lol… 😅😅
Educated guesses are not just luck.
"the harder you work, the luckier you get" is so true. Thanks for another good one, Eric. My '01 2500 HD with the LB7 was a "desert truck" (eastern Washington) for its first 17 years. The electrical gremlins started surfacing within a couple of years of moving to the north coast of Oregon when I retired in 2018. I still absolutely love this old truck and with you and YouTubes help I'm having much success in keeping it alive.
Why are is underneath of fairly young cars so bad over there?
Aren't they undersealed? Are they sent from the factory with bare metal?
it begs the question why do people buy these cars, knowing the underneath is going to last 5 minutes?
What is the guy going to do with the car now it runs? I don;t get it, is he delusional about it being fixable?
Wow! As a mechanic myself,I would not touch that vehicle with a 10 foot pole! Remember, once you touch it, it’s your baby!
A big thumbs 👍 up for the MAIN and a big thumbs 👎 for GM.
Experience counts!
Great job Eric!
Lucky guess or a well educated diagnosis.
Seriously – To me , an inoperative suspension module should not be able to cause a no start condition 😐
How aren't you americans afraid to drive on the road with these rust buckets ready to fold in half on the highway? My goodness.
I've never heard you say PRNDL before, must be @WrenchingWithKenny
Love the lickem stickem
Just remember folks, if Eric can do it, I probably can't. 😂
Wow, the rust is savage in your region. How can one protect the undercarriage from the super corrosion from the salt water?
Could it be the Friends Edition? "Always stuck in second gear"
We use to refer to it in the shop as a SWAG scientific wild ass guess ! Few mechanics left most are R&R men.
Parts of this truck didn’t seem too bad. Might be worth sleeving the frame and reinforcing the x-member, and throwing an alternator in it. New rigs are expensive. Fuel and brake lines aren’t that bad of a job. Might get a few more years out of it.
bring it to me in canada i know lots of people that will fix it
I would love to make a trip over there. To the junkyards and pick up some LS engines.😂 we got A whole bunch of C10s picked up trucks 1969 to 71 a good condition. By chance, you know what the engine's go for in your local junkyard .?
why do you have an air raid siren?
Wow lol what a pile
Soooo crazy cause where i live in northern bc Canada thatd be pulled off rd by guy like u, wouldn't even be allowed to lesve shop unless shop flag it thru ins here saying pulled off rd, unsafe for use
Just goes to show: An expert doesn't come from a school, a fancy gadget, nor from having a bunch of useless letters tagged after one's name. THIS is how it's done!
How about South Main Kitchen? Show your wife more, show family table discussions. Show the 'eats'!
Welcome to modern GM, it gets better. Newer Silverado’s are mexican built ! Good workers but way underpaid! Does GM give you a better price on a new truck. That’s a BIG Negative, they are the next American automaker that will be bought by Stelantis. Just my opinion
You could probably fix one of these in your sleep.
The lady on Green Acres called it the pernundle.
I live in the rust belt and my truck which is only 2 years newer than this vehicle still looks like new underneath due to proper rust coating. Why people don’t make an effort to rustproof is beyond me.
In the "People's Republic of New Jersey" we used to refer to it as the Per-none-dul (PRNDL)
I really want to say thanks for all the content you put out last week. I had the week off and your content reminded me that I did not miss being at work. No matter how much the Secretary of Nagriculture was on me about stuff around the house getting done.
Again, thank you.
Crazy how one module can take down the whole system network
Stuck in second gear? Sounds like it wasn't their day, week, month or even their year, but you'll be there for them.
The sarcastic side of me wants to say :”even a broken clock is right two times a day”. But hey you deserve credit for your experience and insight. It amazes me though the cars and trucks in the rust belt hardly last ten years. One of the few benefits of living in California is the elements don’t dissolve your favorite vehicle into nothing.
Well I’m going to get some gas $5.95🤬🤬🤬 gas in my 60 year old virtually rust free Jeep.
(Another benefit of living in the PROC – Peoples Republic of California)
The amount of rotted out cars that come into your shop just prove a point. The manufacturers in order to perpetuate more sales, build in a limited life span. If you can build an ocean going vessel that say on average lasts 30 years. Then you can build a car for salty roads that lasts more than 10. But less new car sales. So stuff the customers. Just let their cars rot. They will be back for more.
Eric, You are the best. I learn a lot from your videos.
How many times do you have to actually go through the steps to prove that if it walks, talks, and looks like a duck, that it is actually a duck before you can just use the fact that it is looking, walking and talking like a duck where you can be pretty confident that it is a duck without all the testing?
I'm from England and even though we use salt on the roads we don't seem to suffer like you guys with rust, why don't the car manufacturers in the US do more to stop a three year old vehicle from rusting out. If one manufacturer took this on board in time their sales would increase forcing other manufacturers to up their game to keep their customers. Gary 🇬🇧🇬🇧
It's almost criminal to throw away a multi thousand dollar vehicle because of rust… Cars sold in the snow belt should use nothing but fiberglass, stainless steel and every major component be isolated from outside weather contamination…And what's up with the close up of your wife's chest?
Thanks for all of the great videos!
👍
Eric, you mean the PRNY is letting you get away with profiling??? 😉
Thank you Eric again, thank you for thank you for teaching me over the years I learn things from you I do have a question though ion a 2006 trailblazer with a 42 L engine. I bought it two years ago. I’ve been fixing it little by little but the only thing I cannot fix in the morning when it’s cold or no matter what time it is when it’s cold engine, the RPMs goes up and down just a little bit like I want to shut off but only do it a little bit once it starts though it runs fine all the time everything is fine no problems I cannot figure that out why it does that and cold start every time the engine is cold the engine cheeks cheeks just a little bit every time I stutter when it’s cold any idea what that is? Thank you. I cannot figure that out I’m not 100% mechanic I’m learning.👀🌿
Hey how did those powerstop sport brakes go on your mini van, I was curious on an update!
Years to get the experience and know how, thousands in tools. Not all, but some customers, only 1/2 hour charge right, lol.
Does New York State compensate for the damage that the salt they use on the roads causes
Chevy thunder
This vehicle is almost 17 years old. When you think about it, how many 1990 model year vehicles were still on the road in 2007 in the rust belt when this thing was new?
We have a 2010 GMC Yukon that a shady dealer kept throwing parts at it, turns out a couple months later after me going through wiring diagrams the VCIM was shorted to ground possibly, so all I had to do was remove the fuse and she starts every time. symptoms would only occur when it got hot outside once you pulled the ground cable she’d fire right back up took a while to have time to diagnose thought you might think that was interesting. You’re the best thanks
PHAD in this corner and in the other corner we have SMA.

What scan tool were you using? I can tell its some sort of Autel.
"these 6.2 are so awesome" was that sarcasm or do you real think that? You bad mouth "chevy" so much I can't tell anymore.
Yes Eric, prior experience with these GM junks is a big help where you live in the salt belt! You would think GM would build them suvs and trucks better for those conditions!
Rusty crusty 😅
Pro golfer Gary Player was once quoted, "The more I practise, the luckier I get." I think that may have some application here.
Good tip. Experience wins again!!! Thanks Mr. O. Another quality lesson by the master!!😊
Imagine having a walk outside and someone says from an open garage «Hello there viewers! And welcome back to the South Main Auto Channel!» 😃
I will never visit family in Bflo. at Christmas again. They can come down south so I can keep my car alive. lol.
I didn't know you had a dog 😮 never stopped yapping though your whole video 😂
Hi Eric, Can you see why I had to leave GM? I had a part time job helping a friend start up a repair place and everyday I saw the stuff I was involved in developing at GM 8 or 10 yrs earlier, come in just dilapidated and rotten. I was embarrassed to tell any of the customers that I worked where their junk vehicle was dreamed up and proven out.
All those meetings I went to where management harped on everyone to do everything exactly correctly and make certain that we didn't cut a corner that might hide something that would fail and they'd have to eat under warranty. In reality what they were saying was the vehicle must make it to the end of the warranty period. Nothing more.
I always thought they wanted to build it so it would last. After all it was GM: The proud makers of Cadillac, Buick, Oldsmobile, Pontiac *(the city nearest to where I grew up) Chevrolet and GMC. Not to mention all the companies GM played around with ownership of like Subaru, Saab, Hummer, Isuzu, Vauxhall, Holden and I could go on and on. I mean they produced the world's best known Diesel, "The Detroit Diesel." With anything from 2 cylinders to 16 The Detroit Diesel powered everything, and they had a parts network that was worldwide.
But: WRONGO BUDDY!! The upper management flew into DC on their private Jets to beg for taxpayer dollars for a bailout after they committed Bankruptcy. I stayed after the Bankruptcy because I lost so much $$ in 401K stock savings and stock options I received in lieu of money, but I finally had to go. Why on this earth a company who was as famous as GM would stoop to the rust out crap out mentality that it has is way beyond me. Thanks for the embarrassing video. ben/ michigan
Just an FYI for ya, Eric. There is no Class 2 Network, more commonly known outside the Corporate GM Proprietery realm as SAE-J1850 VPW (Variable Pulse Width) on this vehicle. This is a GMT900 Program based Truck. The last year for Class 2 on these particular Trucks was 2006, for the Previous Generation GMT800 MCE-3 which were built from 2003-2006. Class 2 is GM's terminology for the 57.5 kbps SAE-J1850 VPW (Variable Pulse Width) . The Lower Priority controllers on this Truck all utilize the 33 kbps SWLSC (Single-Wire Low Speed CAN). The higher priority controllers all utilze GM LAN CAN, which is GM's terminology for their 500 kbps Dual-Wire High-Speed CAN Network, also known as SAE-J15765-4 in the aftermarket realm. There is no Mid-Speed CAN Bus on this Truck. Keep up the Good Work, Eric ! You are doing us all a Great Service, spending so much of your own time making these videos an sharing your knowledge & skill with all of your Videos. Thank You. 😊
With the frame rot in New York or shall we say in the salt belt I don't think I can afford to live there I believe I will stay in the south. By the way great job Eric
