TCB red-lighted me 3 times in 400 miles. I figured it was the power plug backing itself out, but the "lock" on the 7-way door was still in place. No codes are being thrown. That attention getter loud beep really gets your attention!

As it is so intermittent I can't find a problem. Anyone with an idea? I've wiggled every wire I can find at the rear of the truck. Ummmm, that said, I have not tried under the dash.

 

You can get the trailer disconnected warning any time anything in that circuit loses connection. Can also be at the backside of the seven pin as well as on the trailer.

Not too worried YET. I'll find it sometime. It never did it on the way north (400 miles), just on the way back home. When it cools off here I'll back the truck up to the RV and plug in the electric and start wiggling. (That ought to really LOOK cute!) Maybe I just ought to wiggle the wires! LOL

 

I guess you could do both and get some pictures for this year's Christmas cards!

I hate electrical...almost as much as I hate glass.
