I have a code coming up on the dash saying TBC Fault. What does this mean? Thanks.

Thanks for the info. I did have the dash apart the other day just enough to get the after market stereo out to check for a loose speaker wire?? Maybe I nocked a fuse loose??

I started my truck, warmed it up, and I was driving with no problems but when I came to a stop the truck shut down. I waited about two minutes at most, started my truck and I drove on. This has happened numerous times wether I am coming to a stop or if i am already stopped. On a couple occasionas when I try to restart my truck the TBC light is flashing. I know for a fact that this is not a moisture problem because i have already checked...does anyone have any suggestions? you can contact me at ral.ent@live.ca I would really appreciate the help

i was told it was a trailer brake controller issue

My buddy is having the same problem on his 05 6.0. We were out driving and he got on it then it shot off all of a sudden and the turbo barked real loud and now it wont start at all. It says on the dash TBC Fault. I unhooked both battery's to try to restart it or clear it but that didnt't work. Any suggestions??

The TBC is the trailer brake controler. There have been a number of issues with the TBC.
By most accounts it is internal circuitry problems of the controler. There was also cases of moister getting in the firewall plug of the TBC circuit.
I think you have another issue going on as the TBC has nothing to do with engine control or function. [This is for F250Stroker08]

Whoa Guys the TBC fault has nothing to do with your engine at all.

It means either A you have a bad ground on your trailer. Or B your cable on your trailer is too short and causing it to pull out of the plug or C you have a short in the factory trailer harness wiring or the plug is gunked up

Thanks guys. I didn't think that would be causing the truck not to start. It just happened to pop up when the truck shut off and wouldnt start. Just wanted to check and see what it meant.
