SERVICE INFORMATION
Got a vehicle with any or all of these symptoms:
- Rearview camera displays an image randomly
- Turn signal indicators come on randomly
- Cruise control cancels with turn signal or hazard light use
- The VSA indicator comes on with VSA DTC 68-1 (brake pedal position switch stuck off) or 68-12 (brake position switch stuck on)
If the vehicle has an aftermarket trailer hitch, and it's causing a back feed, that could be the problem.
Let your service consultant know that they should talk to the client and get approval to remove the trailer hitch's aftermarket wiring.
Once approved, remove the wiring, and test-drive the vehicle to see if this gets rid of the symptoms.
