Well I hoped I would be back on the road, but not to be. I replaced both the trailer brake switch and the control module, disconnected the battery for 3+ hours, touched connectors and no change, just keeps cycling all the codes. Harness maybe? Talked to the dealership even though my bumper to bumper expired 2 months ago, I still have the power train warranty. Don’t no how good that will do me. Repairs are supposed to be covered if the vehicle will not drive and it’s from manufacturing.They said it is in safety mode that’s supposed to protect the vehicle. Who knows. Very frustrating. Going to check whatever ground connections I can get to. Have an appointment Monday that I really would like to avoid. As I’ve said, any advise would be greatly appreciated. Hope everyone has a good weekend.
