Shops...Dealers...Parts Cannon FAIL! (Escalade CAN Ghost) 

Your comprehension of automotive computers and wiring is out of this world

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.

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. 🤟🏻🤟🏻🇺🇸🇺🇸🇺🇸

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

Can you imagine how much money he would have saved if he brought it to you first? 😂

Wow! When I saw the problems and the box of stuff, I was thinking it was going to be expensive. Great job.

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.

...another amazing diagnosis and repair Ivan....really enjoyed the video...keep 'em coming... 🙂

WOW IVAN, You are the best. Thank you for being here. Bob from NYC.

Bidders at auctions will sometimes disconnect or even break something to get a better deal

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 👍

Great lessons here. Thanks Ivan!

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 RU-vid see it 👍

Awesome repair...

Isn't there a function in the scan tool to relearn Brake Pedal Position? Seems like I saw Eric O. do this before.

Well done L/S

Customer supplied parts next best thing to NPR

Most techs vision gets blurred when they look at a wire diagram .

Which classes did you take to learn network?

Sure wish we had a true mechanic like you where I live instead of these parts changers

Need to get a body mount camera ?

Sometimes I wonder what a come to meetin on Copperhead road might bring here?

You need to do an extended test drive around the hood and impress the homies, haha

I'm going to say it again the customer should have come to Ivan quicker and it would have been sorted cheaper than replacing the wrong part's

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).

You and Eric have taught me not rely on multimeter (ohm) checks on unloaded circuits. Awesome video!

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.

17:06 That ticking is a broken rear exhaust manifold bolt. Chronic issue on the GMT900 trucks.

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.

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.

Understanding how things design to work is the main key Great job as usual

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 !!!

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?

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.

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.

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.

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.

Great video! Ivan, in a situation like this, let’s say the diag took 10 hours, do you bill the customer for ten hours of labor?

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. 😂😂

I'm 3 minutes in and making a comment, not good. Ivan check the battery ground cable for correct resistance. 2007 Silverado here. Ask me how I know.

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

OEM brake switch. Aftermarket are junk. Common problem on these trucks.

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

California and back in a 07 Cadillac bought at auction?? NOT ME NO WAY!!!!!😵‍💫

If only you could diagnose my car as I don't have a "Ivan" in Australia 🙃

Ha ! We routinely get auction cars that have things messed with, i guess its to get a better bid if the car has issues. Btw, I wish the RU-vid censors could filter out the jerks that post porn links in the comments like they censor other comments .....

This shows the real difference between a mechanic and a repairman Way to go Ivan

That brake switch is notoriously bad for GM.. I have replaced 2 in a 2008 Silverado

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.

Liked the zip ties. Why risk it coming out again.

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.

Thanks for the in depth diagnostic and repair. Always fun to follow along with you. I learn so much.

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

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!

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!!

GM. Still having problems with brake switches after 30+ years.

I can’t see buying a car with issues and unknown history from an auction as a cross country road trip vehicle. There is a lot of nowhere between the coasts.

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.

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

These are my favorites, everyone else fails, Ivan wins! (So does the customer)

The "partially installed GM clip" caused me to shift into 1st gear at 75mph unprompted, pump 21 gallons of gas all over the highway, attempt to shift into 4LO at highway speed unprompted. Apparently you can fool idiots 3 times, but I'm certainly no moron so I switched to Toyota.

In my suburban, when my cruise won't engage, if I just kicked the brake pedal sideways like two or three times that always fixes it. Lol. I think there's two switches but the pressure switch that works the lights works correctly, so I'll just leave it alone for now.

Pi$$ poor Cadillac engineering. They couldn't design a reliable 4-pin switch. Cheap design solution, cheap results. Yet they ask a lot of money for that car.

What about BOB?

Found this "diagnostic" exercise VERY interesting..from a PICO Scope perspective have you investigated, not just the "health" of the CAN Bus, but the actual CAN Bus message content? Particularly interested in TCM "rationality" causing limp mode?

He should have brought it to Neutral Drop where it belongs!

Nice fix! I like the customer's "adaptive tightening device" for the damaged connector!

Ivan, I dont imagine you have a lot of extra time to surf a lot of car repair videos, this BOB issue is a known problem, its best to try 2 scenarios, with and without the BOB. The next problem but not a part of this video. The scanner, extra module, will fool you when the DLC goes to a Gateway, this is the main scenario when a good scanner CAN waveform at the BOB will get you into trouble. cheers

I big problem with the automotive repair industry is good diagnostic is not rewarded. Let’s say a tech spends 20k on the best diag equipment, studies,and trains. Tech “A” without that equipment or knowledge charges hours for diag and thousands on parts. Then tech “B” with the best stuff and procedures finds a bad ground in 45 minutes. There is no reward for the investment. I am a really good diag guy and I left the industry because I had to repair 2 or 3 times as many vehicles as a hack to make the same money. Fixing these problem cars from shops was so easy for me it was funny but after some time I became resentful and couldn’t do it any more.

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.

I have a 1981 Suzuki GS1100E that same color. Great video as well.

On my 08 Avalanche I had the same problem stabilitrack ,traction control, remote start, Bought two from local part stores, no fix, Go to dealer buy same switch , problem solved

I checked out the thinktool pro and it does not list support for 2007 to 2013 model gmc yukon. What scan tool do you use for these models?

You can also file a complaint against the Mechanic governing board in your state in California. That would be BAR.

when the cruise doesn't work or drops out randomly when driving on a GM, you can pretty much parts cannon the brake switch at it and be right 96% of the time. they've been that way for years. that's assuming the dash isn't a Christmas tree and firework show. 🤣 also, at that mileage and heavy tank, they'll likely find themselves in transmission rebuild hell and it in limp mode and much sooner than later. 😵‍💫

On the brake control switches, I found a dried out/broken/missing rubber pad (at the brake rod/pedal mating area)(needed to open the switches), causing the switch(s) to stay closed, when pedal was released.

i bought a new GS750 when they first came out. Kaw. had just came out with the 650 that they said would outrun any production 750 we would park down the road from the kaw shop and when one of the 650s would come by get a race and out run them.

I've been restoring GM cars, especially mid-year Corvettes for 40 years, and I've met many dealership techs through the years. Pretty much every one of them complain all they do is sit in class at the community college for training and can't make any time or actually take the time to diagnose complex issues since they're always in "training" or management is on them to move metal out of bays. At least GM is maintaining their reputation for being their own worst enemy.

Well done, keeping another classic on the road. Seems like a sweet ride!

This vehicle goes to sleep very quickly. Did someone slip it a Mickey? I am suspicious of that. I geuss I have just never been exposed to a vehicle which went to sleep that fast.

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.

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

But, but, but... How did the customer end up with that new brake switch, who made that decision and why? (Or: What am I missing?)

I have a 2016 Ford escape SE that had an issue with the brake light switch would stop working and cause my cruise control to fail but my brake light still worked and I found that if I used my foot and pulled up on the pedal instead of depressing it that I could set the cruise control and that every once in a while if I would try to set the cruise and it didn't work I just put my foot under the pedal and pulled up depressing the pedal a bit, Obviously I replaced it and have not had an issue since

1:31 trucked in from 5 hours away ... someone has realised your ' The Man " to fix it .... NICE

Hey Ivan just curious, how much a diagnose such as this one roughly cost? Thank you and great job!

I'm thinking your BoB didn't have a good connection on pins 4 and 5 or the internal circuitry was interfering for your scan tool to not comm. On lo speed

the owner should TRADE all those parts in ... for ANOTHER car!

Is the 60 ohm test only good for GM? Or anything with a high speed CAN bus?

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🤣

Why didn't you help the customer and fix the tire monitoring system? You fixed almost everything else, why not do the whole job so the customer gets his car back 100% fixed?

The owner is coming to California, on purpose? Lol. Love these videos, Great diagnosis video, again.

Why wasn't lithium grease placed back on the brake switch. Premature wear will be a problem.

Pro tip for sticky connectors Soak with wd40 and blow off with shop air Rinse and repeat

Another three gremlins snuffed out by Ivan! This was a really instructive video for those of us who haven't diagnosed canbus stuff yet

Man...there is no mechanic like you...you diagnose the absolute hardest issues successfully.

I’ve had BOB issues beforeTry with the test leads unplugged next time

Great job & entertaining too ; ) Love the way you keep going through to the root cause, so satisfying - thx.
