Everything has been tested, trailer works as it should, no faults no ground issues. Doesn't matter whether a trailer is connected or not now, service trailer brake system is a fault at start up. This isn't something simple those things have all been trouble shot or replaced.

I have had issues with trailer lights since I purchased the truck new. This summer I decided to really dig in. I replaced the exterior trailer receptacle, the trailer light / brake wiring to the receptacle, and the trailer lamp control module. Fuses are not blown. After replacing all parts truck was giving me a trailer brake connected fault randomly, and check trailer lights fault consistently. Now it gives me service trailer brake system on start up. Dealership is indicating that faults for all lights and trailer brake are showing. They only thing that has not been replaced with OEM parts, is the harness itself. What am I looking at the finally remedy this problem? Its just aggravating at this point, and borderline undrivable with a trailer due to the constant messages that are popping up while driving.
