: Rear park assist help needed?

03-25-12, 03:55 PM
Hello, just bought a 07 escalade ext and when put into reverse the dash reads "service rear park assist". The red light stays on in the back and the light on the switch to shut off is on. Cant seem to get any codes. I cleaned the rear sensors...any other ideas?

I had the same issue! A Sensor is bad and or the wire harness has a problem. Start with the harness bcuz any gm dealer can fix that for less than $100 if its just a chafed wire but to replace a sensor is upward of $600 for one.

Sorry to hear that, Yamaharx-1! If the problem persists, I would certainly recommend a trip to your dealership for a thorough diagnosis. Please keep us updated, and don't hesitate to email me at Katie_Lucille@gmexpert.com for further assistance.
