2019 Chevy Dually - Trailer Brake System message
This message has been popping up more and more lately. Yesterday I was on a rough gravel road and it was popping up and going away every few seconds. Got on the highway to head home and it did not come up again. By the way - I have not had the Monte hooked up to the truck since July 2023. Message comes up with nothing plugged in.
My guess is there is a loose wire in the bed plug or on the lower hitch plug. Can anybody advise what to do to fix this?
