TBC reading TBC fault at random
I dont know whats causing it.
I first noticed when i had a trailer hooked up, the TBC never shows a "red" trailer icon, but the dash reads "trailler disconnected" or TBC fault while towing, but the trailer brakes always work, so do the lights :/
I then realized it does this on 2 trailers...
Then when NOT trailering, the truck reads trailer disconnected and tbc fault sometimes at random.
Im thinking its a short in the wiring?
The preivous owner had a company install a gooseneck hitch AND 2nd put in INSIDE the left side of the bed. Both apparently work, are chean, dirt free etc.
Would this be caused by the 2nd adapter for the gooseneck plugs or is it something else?
