TBC Fault...

Hey guys, so a few weeks ago I was towing my work trailer (16' enclosed trailer) and I felt as if my brakes on the trailer were sticking a few times... I brought it back to the place I got it and they looked it over, and we discovered that my factory trailer brake controller was locking the brakes up slightly. We then just unhooked the trailer brakes at the battery of the trailer for a temporary solution.

Ever since then, whether I am towing or not I get the TBC fault code on my dash CONSTANTLY... My blinkers do not work when the TBC fault code is up, and now my AC is only working every once in a while... I don't know what to do???? Any help would be appreciated...

PS it's an 05 F250 CC SB... Thanks guys

Check your fuses. But sounds like your trailer places solution caused some issues with your PCM.

All they had to do was change two wires around on the trailer.

Take the truck to them and tell them to fix it right

Check the 7way harness at the back of the truck. They probably knocked it loose when they checked everything over

I bought my truck with the TCB fault displaying. It has nothing to do with the other electric components on your truck. You have other issues, probably to do with the fuse box itself, leading wires to the fuse box, etc.
I've towed with the TCB showing and I can tell the brakes are not working, but in tow mode, it hasn't been an issue with my F350 on larger braked axles and only towing a 6k trailer/jeep. I drive defensively when in tow mode as well. To make it not show, you need to push the speed gauge button.

I do have an aftermarket controller to toss in, just haven't gotten around to it just yet. Soon. Soon.
