2015 PSD Faults
I'm getting 3 faults:
Wrench symbol
Service Advancetrac
Check Brake system
The transmission goes into limp mode and downshifts without shifting back up unless I stop and put in park.
Someone said its a bad wheel bearing, so dont drive it. According to the manual, the wrench symbol means a drivetrain or AWD fault has been detected. Its got 4wd not AWD. Is a wheel bearing part of the drivetrain?
It just had a bad brake switch replaced.
Any idea whats the problem? Your feedback is greatly appreciated.
Thanks
Rick

Problem is you need to scan the systems and see what trouble codes the lights were turned on for. Guessing and replacing parts with no diagnosis is a losing game.
Bad brake switch? Why was it replaced? Did it fix the initial problem?
