I have a 2006 F250 with the built in TBC, all of a sudden my info center and TBC are dinging and showing check trailer or TBC Fault. When there is no trailer hooked up it goes off all the time driving down the road. It rarely goes off when hooked to my trailer. I took of the interior panel below the steering wheel, and can reach the harness going to the TBC and if i touch it with the truck running it will show that TBC Fault. Is there a TSB about a bad controller or connection? I need help ASAP I am towing a trailer from MI to New Orleans in two weeks. Thanks!

this is a common problem, there have been a few threads on it. i think there is a diode/resistor block that goes bad, and most dealers are stocking them, and takes under 1 hour to fix.

yours may be a different problem, of course.
