Dealer said “they couldn’t duplicate the condition”! Of course they couldn’t, all they did was connect the truck to their trailer simulator. Obviously didn’t read the TSB. They did say there was a computer update so maybe that will help. Towing in another week so I’ll see what happens. Probably going to call GM and start a CASE with them. Has anyone else have the condition come back after the TSB was bone?

Had the TSB done about 4 weeks ago. The last couple days the “check trailer wiring “ issue came back. After thinking through all of this there might also be an issues driving in the rain and moisture. I pulled fuse 84 yesterday and it did not make any difference. The first time I experienced this was also driving in the rain. Going into the dealer Monday. However I need to drive all day in the rain to get there.
