Hey everyone, I’ve been having a wiring issue between my TV (2014 Chevy Silverado 1500) and my TT (2011 Coachmen 28DDS). My issue is that I keep receiving notification pop ups on my trucks dash (“check trailer wiring” usually immediately followed by “trailer connected”, but sometimes it may take time for the “trailer connected” notification to appear again). My truck has manufactured Integrated Trailer Brake Control (ITBC).
The TV lights (turn signals, brake lights, camper lights when TV lights are on) all continue to function properly even when these notifications come on and off.
Also, the notifications occur sporadically; sometimes popping up 20 times in a minute when I’m driving or other times not popping up for 5 minutes or so.
My major concern is that when the “check trailer wiring” pop occurs and is not immediately followed by “trailer connected” my trailer brakes don’t work. I know this because when I adjust the trailer brake gain on the ITBC the brake gain is grayed out and isn’t working or when I manually adjust the brakes stopped the TT doesn’t stop the TV like when the TV brakes are properly functioning.
I initially suspected the issue was due to a ground wire being unplugged near one of the TV brakes from a 3M schotchlok 314 3 wire connector. I replaced all the connectors as they looked pretty rough. However, I continue to have the same initial issue. Does anyone have any thoughts? I’m thinking I may have a short in a wire in the underbelly I can’t see.
