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

Рет қаралды 116,258

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.

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).

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

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.

@scientist100 2 жыл бұрын

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.

@groosbro1 2 жыл бұрын

@@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.

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

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.

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.

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🤣

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.
