Shops...Dealers...Parts Cannon FAIL! (Escalade CAN Ghost)
ฝัง
- เผยแพร่เมื่อ 5 ส.ค. 2022
- Customer towed his 2007 Cadillac Escalade EXT to my shop from 6 HOURS away.
He bought it for cheap because no one could figure out this intermittent mystery CAN communication problem. PARTS CANNON has been fired by several shops, dealers, and the owner himself!
He wants his truck to be cross-country ready, so the pressure is on!
Let's start from scratch and diagnose this CAN BUS.
Any Parts Required?
After repairs I discover that the CRUISE CONTROL does not work...time for Bonus Footage :)

Here’s how it went down at the shops:
Technician: cool, I get to diagnose an interesting problem.
Supervisor: get that thing out of the shop, it’s holding up a bay.
Very very true
Yup, “condemn it! We are in the business of selling cars not repairing them”
And that is a totally rational business decision.
Wasting the customer’s time and money is not a good business decision.
exactly.. not making the greedy a hold any money...
This vehicle overall is pretty much the ideal candidate for a cheap auction find. Seemingly frustrating issues that aren't that complex to diagnose if you engage the brain/tools. I bet the owner is thrilled and this looks like a really nice conveyance to travel the country (except for fuel economy of course).
And whatever else pops up on a long trip. Might be fine- might not
If it’s a 5.3 with vvt, disable vvt and gas mileage goes up, power goes up….and reliability soars!
You and Eric have taught me not rely on multimeter (ohm) checks on unloaded circuits.
Awesome video!
This video also shows how many inept shops and dealers failed to find the issues and repair them...
Diagnostics requires patience and the ability to read and understand a schematic
It's a sad day in America and a happy day for the customer, that he found Ivan... because he has a great head on his shoulders
Great job as always my friend, keep up the great work.
i think biggest issue is dealer doesn't want to pay tech's for diag work so they won't do it dealers are the worst at firing the parts cannon at a huge mark up and they get alot of their parts fro the local parts store at a huge mark up and not from mfg like they charge for
This guy has a brain he is just interested in the problem and fixing it not the prospect of charging the customer big bucks.
Profit vs reputation and abilities.
Understanding how things design to work is the main key
Great job as usual
Your comprehension of automotive computers and wiring is out of this world
This shows the real
difference between a mechanic and a repairman
Way to go Ivan
17:06 That ticking is a broken rear exhaust manifold bolt. Chronic issue on the GMT900 trucks.
alot of dirty stuff goes on at auctions, people will sabotage vehicles so others dont bid as high, then they buy them, and fix what they sabotaged. great job !!!
When I see a 37 minute video, I think I never have time to watch and dread opening it, then 37 minutes later, I didn't want it to end.
You're always miles over my head but I'm always fascinated.
Thank you, I believe you are doing the world a favor.
Ditto every single thing you just said!!!
Isn’t that the truth!
really interesting one to watch too, always enjoy his approach to problem solving
I love they philosophy of repairing, not replacing, parts. Unfortunately, manufacturers don't want to make parts available anymore. Had to buy a new starter (assembly) because the solenoid wasn't available separately.
Great job. Thanks.
Not to detract from your diagnosis in the slightest, Ivan, but I'll bet the GM dealer could have diagnosed it properly if they had really wanted to. But what they really wanted was to sell the customer a new vehicle.
At most dealerships the only useful department is the Parts department 😅
Yup, repair a few grand/replacement 80k+
Yes, never a good idea to bring a vehicle that old to a dealership.
You haven’t detracted, Ivan is the man, very few dealerships these days can actually do what he does, I’d say you are dead wrong at 98% of dealerships these days…. They’d throw about 5 grand in parts and labor at it and give it back broken even if it was under warranty… you almost need a masters degree in mechanical and electronics engineering to correct many issues properly anymore, and that’s not a joke…
The last time I brought a vehicle into a dealer for a oil change they damn near wanted to rebuild the whole thing. But they had a good deal on trading it in on a new car this week.
Can you imagine how much money he would have saved if he brought it to you first? 😂
You are awesome. You are the best I've seen on youtube diagnosis of complicated problems and you acturally fix the problem with most no parts needed. God Bless.
I was chasing a similar brake issue on my '07 Chevy Trailblazer. Kept getting a C0131 code which leads to a failed EBCM, and I was ready to replace the unit until I found an OLD article about how the computer expects to see the brake switch applied before seeing pressure in the brake pipe.
I set the scan tool to graph pressure and brake switch position. Turns out the aftermarket brake switch "timing" was off by a bit and the computer was seeing pressure before brake switch actuation.
Put in an OEM switch and the problem disappeared.
Dont be fooled, some brake switches can be adjusted by a bit before you tight the bolt down and that signal will come as soon as you press the brake pedal. Most GMs have this lever type switch that if you move it slightly, it activates. It is just trial and watch with the scanner to see if you need to move it a bit more. These type of switches usually have a two way switch, one for the brake lights and another for notifying the BMC.
@@scientist100
The car's of that vintage didn't bolt in, they were mounted on a post and retained by a clip. There wasn't any way to adjust the switch other than bending contacts, why bother for a $20 OEM switch.
I love it when you say all done so I check the timeline, observe there is plenty of video left and sure enough, massive mystery pops it's ugly head. I think he knew it was a problem but every thing else that was going wrong masked that break switch.
Dealership Technicians are never trained properly some just figure it out some never do……Sad world we live in that is why my Family bring everything thing to me Retired 35 year Mechanic. Great Job Ivan as Usual. 🤟🏻🤟🏻🇺🇸🇺🇸🇺🇸
There are great techs out there at dealerships...but usually they start their own shops because the system doesn't let them grow to their full potential :)
Wow! When I saw the problems and the box of stuff, I was thinking it was going to be expensive. Great job.
Another awesome video on more than a few levels ,calling those bikes vintage makes me feel old , glad you took time to go for a good ride with your brother . I imagine the weather is perfect for it this time of year. The amount of money spent on that box of parts would have been considerable I hope you charged top $$ even though it was a relatively short diag.
When I had the problem with my cruise, you could be driving along with it on and hit a bump and the cruise would turn off. Gave the pedal a few taps with my foot and it would work again until I hit another bump at which point it would kick off the cruise. Replaced the brake light switch where I could repeat and rise with the same result and all has been well ever since. Thanks Ivan
Great job as always. As a dealer tech the hardest part of the diag is dealing with all the distractions. You can never just put your head down and figure things out. That's why alot of dealers shoot the parts cannon. The more I watch your videos the more I want to leave the dealer and go into the Mobil diag business.
You won't regret it... I wouldn't work for anyone else 🙂
Good advice. In my day the few good ones faintly similar to Ivan at my dealership.left an found their silver lining. Good luck to you..
i've been thinking about going to be a tech at a dealership but I always wonder about how fast the car needs to be fixed. I personally think I need to take my time
Man...there is no mechanic like you...you diagnose the absolute hardest issues successfully.
Ivan is more knowledgeable than the average mechanic, he's an Engineer.
I worked with medical engineers and rarely I saw people that knew what they were doing. There was a true engineer that would create a plan and execute a plan with documentation that showed what failed and what changes could be made. Those kind of things are not often seen unless you have a knowledgable person that is willing to do the job.
welp i learned something new! you can check the terminal resistance with the battery connected aslong as the vehicle is asleep! very cool and good to know
Thanks for the in depth diagnostic and repair. Always fun to follow along with you. I learn so much.
My first motorcycle, a brand new red 1982 GS 750E. She was fast and never failed me. That blue one looks almost the same. Also had a great tank bag. Today it's only Harleys for me.
WOW IVAN, You are the best. Thank you for being here. Bob from NYC.
Nice fix! I like the customer's "adaptive tightening device" for the damaged connector!
Was looking at that. It's a zip tie lol. Works.
Holy smokes Ivan. That Is a crazy no parts required fix! Great diag on the network bus comms….and since you don’t have to buy a part it’s technically a NPR repair. You are still the NPR KING!
Well done, keeping another classic on the road. Seems like a sweet ride!
Fixed my cruise by accident.
Pick up on the brake pedal with my foot and my cruise control again on my 2500 Chevrolet Silverado.
Same switch on most all Chevys
Love those 6.2L GM's. Amazing simple repair...can't even begin to figure out how much he paid those other shops and no cigar.
...another amazing diagnosis and repair Ivan....really enjoyed the video...keep 'em coming... 🙂
Great thinking! Great diagnostic and repair! I was thinking it could be a module bringing down the network, but an improperly seated connector under the car works as well :-) And the only part required was already provided, before diagnostic! How about that?
Another three gremlins snuffed out by Ivan! This was a really instructive video for those of us who haven't diagnosed canbus stuff yet
Wow, he came all the way from New York City! He probably should have taken it to Staten Island and waited for your arrival, Ivan. LOL
Great job Ivan. I really appreciate your process. Have a great day!
Nice video. I see after working on broken cars all the time you enjoy vintage motorcycles. No computer problems there. Also the horses are fairly reliable. They only have one control module that can be fairly stubborn and when malfunctioning resorts to bucking, kicking and biting. 😂😂
except in mares, where apparently, it comes broken :P
Wow great work on this, I bet this family is happy!! I'm glad you had fun with your brother!!!
As soon as I saw the parts cannon box, I said "watch...it's something super simple". Sure enough, it was a loose connection. Goes back to the "more you mess with the plumbing the easier it is to plug the drain" line of thought. Seems like training to trace problems like this isn't common. Yours is the only channel I watch that actually scopes the data lines. Bet if the very first person to look into this did that they would've caught it. Great vid and quite educational. I think I need to buy a scope before I have major issues with mine or my wife's truck.
in star Trek heavan, scotty just smirked at that
Eric O. scopes the data lines too, but he and Ivan are unicorns in that regard I think.
Vo
Gotta love the NPR fixes!!!! And oh! The easy find of that loose connection! Gotta be so easy job for you when the costumer says wow, so easy! Haha. I love caddys. I used to have Escalate suv. Very fancy those were, especially the 6.2 motors! Gotta have the scope and breakout box to find the issues! Great job Ivan!! You deserve couple beers!! Plus, we need video of you riding with your brother in some off roading and on road too. Haha 😄 🤣 this is very helpful in case if i come across to an issue
Man your videos are awesome and I've learned so much I appreciate you putting them out and sharing your information one thing is though I wish that you would show more detail about how you hook your scope leads up when you're doing testing
Great job & entertaining too ; ) Love the way you keep going through to the root cause, so satisfying - thx.
1:31 trucked in from 5 hours away ... someone has realised your ' The Man " to fix it .... NICE
Thanks man, very good work… You make it look easy, it isn’t, you are definitely a master…
At first It was scary but you nailed it, step by step...diagram is a must
First rule when buying from an auction , check all connections for partial open and fuses for missing. People monkey with these vehicles during inspection to dissuade other buyers to lower the price.
I have done some auctions for Turf Equipment and I can attest that people at auctions are evil. They will take keys and sabotage stuff just like Aerialscope said.
Yep!
@@rhysarthur7305 YEP!
I work as a repair tech for a large auction company. Some of the shit I see is beyond belief, especially on sale day. We've had dealers thrown out because they were caught tampering with vehicles. It's a completely different world from retail repair. Assess, repair, get it through the lanes, move on to the next. Once these vehicles are sold, I'll never see them again. We have a saying that gets thrown around the shop quite a bit.."these cars are here for a reason". Goddamn right they are. LoL
Great repair. The frame looks pretty intact on this truck. Looks like it has minimal rust.
How many of you watching this guy because the shops you went to throw parts at the problem(s) and still couldn't fix it? Mechanics this good and honest are hard to find.
These are my favorites, everyone else fails, Ivan wins! (So does the customer)
U use your M12 light ratchet a lot. I like mine too. Light and controllable. I also got the HF long skinny 3/8’s. It’s light and fits in a lot of places. I have the long Milwaukee Fuel too. It’s heavy and super powerful. The right tool is nice. Great diag btw!!
Great lessons here. Thanks Ivan!
No lithium on the brake switch not a big deal, awesome repair good video. I need to get breakout box!
I have a 1981 Suzuki GS1100E that same color. Great video as well.
And that was close enough and fairly complicated and difficult to find at the same time ! Nice procedure bother
Hi Ivan absolutely brilliant work by a legend of diagnostics👍 you must have filmed this prior to me having a little dig for not putting your seatbelt on pre driving🧐 I’m sure your beautiful wife doesn’t want to be a widow nor do we want to be Ivanless! Gee I must be getting old! Stay safe mate from Australia 👍
Another great video Ivan! Well done!
You the man Ivan. Love your work.
Thanks Ivan, well done, fascinating
The owner is coming to California, on purpose? Lol. Love these videos, Great diagnosis video, again.
Great job, best video I am learning so much.
There was probably a reason that the original switch had all of that lube on it. Great job on the diagnosis and the methodology!
"Vintage" bikes,the ones that were NEW when I was working on them,Does that make me vintage too?Great vid,as always!
Ivan the electrical hound sniffs out an other one , excellent Ivan , sounds like a good nick name ....excellent Ivan
I have found working on my 08 Avalanche that all the brake switches from the parts stores and Rock Auto work very briefly. I bought one from GM and haven't had a problem since. Add a dab of Dielectric grease to the slide
Ivan you are the best,l learnt a from your TH-cam videos
So we're going to say the parts cannon worked? Sorta kinda🤣🤣 Great work on the CAN!
Great job again Ivan
Well done Ivan 👍
Outstanding as always
Great job as always 👍
great repair
You continue to amaze me Ivan! A video of your bike trip would be very interesting too! Hint! Hint!
Good work 👍
5 hour tow!
So sad there isn't anyone else closer that knows their stuff!
However, it does say something about your work!
Thank god you didn't replace the goo that was there when you started 😉
As always ... brilliant!
Good job Ivan.
Very good video for the CAN buses. I would check if the connector for the VIC plug in doesn't expect to see strap to a pin on the car.
the bob may not be suppling that connectivity for the VIC.
The brake switch, I see that the new brake switch fixed the problem but I was wondering if the connects may have been phased, i.e. one of connects had to made before the other opened or opened before made. Cams could be used that way.
@35:14 Did you forget to grease up, Ivan? 😉Well done sorting that lot out and for our amusement. ☺👌
Awesome repair...
IVAN, THANKS FOR PERFECT APPROACH TO THIS CASE STUDY. YOU ARE IN AN ORGANIZED APPROACH WHICH IS VERY CLEAR AS CLEAR AS THE SUN LIGHT. WE VALUE YOUR PRESENTATION.
YOU DESERVE EVERY CREDIT, YOU ARE #1. THANKS
Another great job!
An auction vehicle is a _special_ vehicle. The dealership it was traded in at didn't think it was worth putting on their used car lot so they parked it in the back row until action day when they had to tow it there.
That exact style of brake switch was used here in Australia on a lot of Fords in the early 90's and it was very common to see them fail.
I remember we seemed to sell a lot of aftermarket ones when I worked for an aftermarket auto parts store in the mid/late 90's.
Looks like it might just be another wrong decision by GM to steal another manufacturers poor design, or just going with what's cheap and readily available...or perhaps there were lots available for rebranding when Ford stopped using them in the early 2000's..lol🤣
just opened TH-cam to check for your videos and look what I got
If only you could diagnose my car as I don't have a "Ivan" in Australia 🙃
You are fantastic!
Instead of a parts cannon, all you needed was a model 1911 .45. Great diagnosis.
You are the best Thanks for your time Bill N LI NY
Awesome diag 👍👍👍
unbelievable. good one
You are lucky the brake light switch was not a very intermittent problem. Took me a lot of time fighting this same problem on a VW Mk5 Jetta. The brake switch worked 100% of the time on the light circuit side of the switch but 99.9% of the time on the ECM side. Complaint was, car would idle fine stopped at an red light but right after taking foot off of the brake pedal and pressing the accelerator pedal the car would have no or reduced power for 2 to 5 seconds. A very unsafe condition to have when making a left-hand turn into oncoming traffic.
Hi again Ivan great job done but I think you will have to fix the music in the end of the video from the radio before TH-cam see it 👍
California and back in a 07 Cadillac bought at auction?? NOT ME NO WAY!!!!!😵💫
Where's your sense of adventure? xD
My 97 Chevy p/u brake light switch is a bit different and better than that new design but the contacts for the brake light are the same
A quick dressing of the contacts and a slight adjustment fixed it ,no different than the Electro-mechanical pinball machines i have 👍
I have it set hair trigger for tailgaters so i can stay on the throttle and tap/hold the lights without riding the brakes 😅
Parts cannons are awesome!
Great video
My best experience with a dealer was when I installed a brand new Mr goodwrench 350 in my 1979 Malibu classic sport coupe, it had factory bucket seats and an automatic with a floor shifter, I wanted to upgrade the original 267 engine so I opted for a brand new engine, my friends who owned a garage let me use their discount through gm and it was delivered to their garage then they brought it to my house along with the hoist and engine stand. After a few weeks it had a hard time starting almost like the battery was going dead, since it was under warranty they told me to bring it to the dealer and they had to fix it, they said that the number 5 piston was binding, I brought it in the morning by late that afternoon they had the engine out, I went there to look and through the garage window I was able to see my car with the engine out, I had the car back in a couple of days, that was around 1990, it was the dealer I had bought the car from brand new but it changed owners when this happened, labor everything was covered under warranty.
Brilliant as you are Ivan, isn't it very disconcerting that multiple shops and even dealers did not have the know-how to diagnose something that you solved so quickly?! Surely, dealers should perform to a certain, certified standard? What are your thoughts on that? I know you see it all the time but it seems to be a big problem. Dealers should guarantee their work in the same way that you do!
Customers should DEMAND a guarantee from any shop for any service. I don't know why they don't lol!
The mechanical return springs get weak in the brake pedal sensor and cause always on/off problems. Aftermarket ones last about 5 years on GMs
