Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi there, I am cam. I am sorry to hear about this issue on your tuck. The code resets each time the vehicle is turned off so that means the fault is present each time. The most common issues I have found are bad wiring to the plug at the rear, the solid state relay that controls the brake apply and the module that controls he whole trailer brake system inside the rear frame rail of the vehicle, drivers side above the rear axle. I don't suppose you have a code from the system?
