wiring fault on trailer message
Hey guys. Like the title says. I was coming down off the mountains today. 12 percent grade. The message popped up. I still had lights and the trailer showed connected. When I pushed the brake pedal it showed gain but didn't feel the brakes working. So I pushed brake module it showed gain but the truck didn't slow down. Got to the bottom of the mountains unplugged it for a second and plugged it back in. The truck said trailer disconnected but I had lights on the trailer and still no brakes. So I drove a couple hours to get home. Few miles from home message popped up saying trailer connected but still showing the fault. My horn and pedal adjustment works but my forward and reverse on my seat doesn't. Any help would be great guys.

Start checking for popped fuses and/or bad relays. Maybe reach under dash and disconnect and re-connect the TBC cable. Haven't ever heard of this problem before. If those don't do it, open the umbicle cord and check for corrosion.
Oh yeah, one more thing....check for codes.

One of the issues that I had on my F250 with the truck/trailer disconnect warning light coming on was that the Ford truck plug in for the 7 pin connector is one brand, and most pigtails on trailers are a different brand. They are supposed to be compatible, and they are to extent, but they do not fit perfectly and sometimes cause connection issues. What I ended up doing with mine to solve the disconnect issue......once the trailer was plugged into the truck, I used a Velcro strap that was long enough to wrap around the entire plug and little cover that is part of the truck plug-in....and pulled it right. This holds the pigtail in place and I never had another trailer disconnected warning. You might want to at least try that and see if it helps.
I can't remember the brand that Ford uses, but the trailer pigtail was a Bergman
