My 2006 f350 diesel sometimes is having trouble starting, it's cranking but won't start and the tbc fault appears anyone know what that could be?

 

It's something to do with your trailer brake controller. It's either the internal wiring that's messed up or there's a wire shorting out somewhere most likely. It might just need to be reprogrammed or something. You will probably have more help in the 6.0 forums. Either way, I'm sure some of us 6.4 guys are nice enough to help haha.
