HELP!!! Ford Tow Command "TBC Fault" message
#16
I have an '08 F350. I keep getting a beep and the message that I have "faulty trailer wiring" WITH NO TRAILER CONNECTED. I can clear this message with the reset button but about 50% of the time it will come on again the next time I start the truck. Twice I have taken this problem to one of the largest dealers in Minneapolis but they cannot figure it out. What is especially maddening is they don't even know what the "fault" is that the computer is sensing so they are just poking around like blind men. Does anyone know anything about this? - Does Ford Motor Company even know any thing about this?

If your dealer is any good they already know about this issue.

tow command
Hello I bought a tow command kit from ford last year. I have not put it on they yet because i need more direction than the 2 papers that ford gives. I also bought the upfitter switches. Now i'm going to buy the harness and Central Junction Box. My question is with the kit a new master cylinder came with it with a extra plug and i can not find the plug new to the fire wall. If anyone knows please reply. thanks i have a 05 f250 xlt

Interesting thread.
I have a power drain (.5 amps) that I can not isolate. If I pull the "cluster" fuse, the drain goes away so I paid for a new cluster and still have the problem. However, now with the new "updated" as the parts department told me, I get the TBC fault. I put my old cluster in and no fault.
Two things, maybe this is pointing to my power draw. And second, maybe it is just a cluster glitch. Mine came on with no trailer hooked up and I never got it with the old cluster. Now I'm going to check the connector at the master cylinder... Man this is driving me nuts!!!

Seems like a lot of folks having this problem. I'm having the problem as well with my 2006 F250. TBC Fault at start-up. Sometimes it resets, sometimes it comes back immediately after reset. Seems that going over bumps sometimes causes it to trip. It's terribly annoying hearing that bell every time I go down the road.
I don't want to take it to the dealer. I never pull a trailer with electric brakes. Can I just remove a fuse, or will that affect something else in the brake system?
