Your video brings back to Jamaica, with em older bmw's 12 cylinder wiring problem

Thank you for sharing!

Check engine light came on same problem watched your video found the same problem on my car great video

[@DadsGarageDiagnosticSpecialist]

That’s awesome glad to hear you found it. Thank you.

[@ronaldoquintos1675]

I’m working with same symptom first thing I checked is the B+ and it has battery voltage. The electronic seemed to have a shorted component since there is no activity and I traced it to a shorted ceramic SMD capacitor. I charged customer same as new power steering

[@DadsGarageDiagnosticSpecialist]

That is interesting. Thank you for sharing.

[@papparocks2603]

Yeah don’t just tape it up and reroute it that would be too simple

[@DadsGarageDiagnosticSpecialist]

On my own car maybe. On a paying customers car? No. They don’t know any better. It would corrode in a year or so and there when be a power steering failure at some point. Not every driver knows how to handle that or is even physically strong enough when the power steering fails. Thanks.

Perfect job

Well done. The wiring problems are going to be a black eye for gm because of the silverado. The way they route these harnesses is out of control

[@DadsGarageDiagnosticSpecialist]

I have seen some wiring harness corrosion first hand… the size of the wiring has gone down to save weight and the wiring is not tolerant of any outside damage at all. Not sure if it’s a problem specific to GM or not. I don’t work on all makes and models as much like I used to back in the day. Thanks.

[@8gomerpyle22]

Do EVs have this kind of wiring mess?

[@DadsGarageDiagnosticSpecialist]

Yes the wiring harness on an EV isn’t too much different. On an EV there are orange high voltage cables to worry about too. Thanks for commenting.

What happens when no.6 and no.14 terminals don't have 60 ohms?

[@DadsGarageDiagnosticSpecialist]

The modules on the network won’t be able to communicate with each other because there would be a circuit fault. Thanks for commenting.

[@sleepyy_ivann7490]

How can I diagnose the fault?

[@DadsGarageDiagnosticSpecialist]

@@sleepyy_ivann7490check out some more of my videos. I have more tips on diagnosing network faults. Thanks.

[@danthefisherman4793]

​@@DadsGarageDiagnosticSpecialistSo my 2010 Impala has intermittent no crank no start and communication issues with U0073 and U0100 codes when acting up. What could I expect pins 14 and 6 to read when it's running Ok vs When it's having the issues. In other words could they read 60 oms when ok and not 60;when it's acting up. Thanks.

[@DadsGarageDiagnosticSpecialist]

@@danthefisherman4793 yes the resistance should be 60 ohms… If it measures anything other than 60 ohms with the key off, etc. then there is a network circuitry fault. This should be done with the battery disconnected for best results… If the modules are communicating, while you perform this test, you may get incorrect readings

[@DadsGarageDiagnosticSpecialist]

You must be referring to the early electric power steering systems that were and are still problematic. Thanks for commenting.

[@timheersma4708]

@@DadsGarageDiagnosticSpecialist Oh yeah...and after being told the repair was $800 with no guarantee it would be fixed, I wouldn't drive one if it was GIVEN to me. 🙄

[@DadsGarageDiagnosticSpecialist]

@@timheersma4708 yea I still see them from time to time and the power steering system continues to be problematic for people.

[@badboytommy187]

That is a very good diagnose repair. But you cause the customer a lot of money 😮just repair the whole harness for just one shorted wire . $$$ 😢

[@DadsGarageDiagnosticSpecialist]

Thank you very much! I feel that on my own vehicle I probably could have repaired it and made a long lasting successful repair. As a professional working on a paying customers vehicle, however… Especially because we are dealing with a power steering system… The consequences of a failure while driving are potentially deadly. In this case I consulted the OEM repair procedures and they want the whole cable replaced if there are broken strands. Although the repair was a little more expensive than it potentially could have been with a “cheaper” repair. The vehicle is now repaired like OEM and everybody involved is very confident about the repair. Thanks again for the comment!

If it causes a crash and loss of life guess who is getting sued. I understand why he would do that.

Extremely amazing. You need brain to find the issue.
