"Difficult Diagnosis" 1

Customer states multiple electrical issues intermittently...this kind of scenario can be very challenging and requires extra planning and logistics.
What does a difficult diagnosis look like to the so-called diagnostic specialist?

Somebody wanted difficulty? What a demand. Thanks. ;)

[@DadsGarageDiagnosticSpecialist]

I try to give the people what they want.
Thanks.

That's a 2020 denali. And the door panel, a power already broke. My apeller's took me a while to damage done, but they never broke even though my truck was built and GM bankruptcy era. What is wrong with GM belt quality? The only thing that breaks a lot is the radio best of trim. I've gotten lucky and found news ones at the junkyard. There are 45 bucks on eBay.

It sure seems like they use a lot of plastic parts with economy in mind… that’s how just about everything is built these days. Cheap and max profit.

I had a 21 GMC Sierra 1500 3.0l With a lot of U codes and was intermittent and found the Front view camera would get Hot to the touch and cause the problem. I replaced the camera and the connector with it.
You should do a toolbox tour to.
Also to replace the 2.7l engine I done it thru the front.(the comment I made on the other video) Thanks.

[@DadsGarageDiagnosticSpecialist]

Excellent information! Thanks for sharing! I am suspecting the front view camera module too, I’ve seen them run hot also.
Good to know on the 2.7L I haven’t had the pleasure of working on very many of them.
Some would get upset if I did a toolbox tour and showed them all my basic rag tag tools and all the stuff they don’t need to buy lol. Maybe some day.

[@Zlambert99]

Yeah, you could wiggle the connector to the camera and make the problem happen when it was hot.

[@DadsGarageDiagnosticSpecialist]

@Zlambert99 I might have to give that a try next time I see the vehicle.

You know what I hate no new about these new navigation systems, the mylink system, they discontinue the updates. 4 20 15 to 2020.

[@DadsGarageDiagnosticSpecialist]

It’s probably best to just mirror it off of your phone anymore.

[@sohailrabani]

Intermittent and communication on multiple can lines are really difficult oeto diagnose

[@DadsGarageDiagnosticSpecialist]

Probably some of the most challenging electrical faults to find.
Thanks.

Here's a mean 2008 Silverado. Steering goes out just for place to power steering pump. 20 Silverado. Power steering doesn't work. Oh, it was just a ground and it took me 6 hours to fix. Or is my power steering rack That's $7000.

[@DadsGarageDiagnosticSpecialist]

I have an electric power steering video too. Most all of the GM steering racks are wired the same and work the same so check it out.

[@danielb-c9100]
