"check trailer brake"

Called the Chevy dealer and the GMC dealer in my area. They’re both idiots said they have no idea what I’m talking about. Said they can’t look up the bulletins either. I hate dealers.

I have not had any issues with my system on my 2024, until this week and of course after responding to this thread. My flatbed that I have been using consistently, had my dash going on and off with "check trailer brake system" while bringing home 3 yards of loam. I need to clean the connections and trouble shoot from there. You guys jinxed me....

Gave a little bend to the tabs on the truck socket and had no issue with the trailer the other day

I don't recall did you get the inline load resisted for your trailer plug? I added LED resistors to my trailer lights, Solved the problem
