I have an '06 F350, get in the truck today, turn the key on and TBF comes on the command center, says press reset to clear, I do it and it clears, then the odometer comes on. but now there is ---F on the top right above the miles. Has anybody else seen this ---F? I know the TBF is trailer brake fault, and now when the key goes on, it also comes back.
The ---oF looks like a temperature gauge, it was never on the display before. The TBC Fault again showed up this morning. I guess it's time to schedule service.
TRAILER FAULT: The TBC is capable of determining certain faults in the vehicle wiring and trailer wiring/brake system. These faults do not mean there is anything wrong with the TBC. This message is displayed when one of the following faults has occurred:
• Short circuit on the electric brake output wire: If the TRAILER FAULT message is displayed with no trailer connected, the problem is with the vehicle wiring from the TBC to the 7–pin connector in the bumper. If the message is only displayed with a trailer connected, the problem is related to the trailer wiring; consult your trailer dealer for assistance.
• Trailer brake overload: The trailer’s brakes are drawing too much
current; consult your trailer dealer for assistance.
Note: Your TBC can be diagnosed by your authorized dealer to determine exactly which trailer fault has occurred; however, if the fault is with the trailer this diagnosis is not covered under your Ford warranty.
I'm not too worried about the TBC Fault, except nothing changed from one day to the next. The new temperature reading on the dash is what baffles me. For the past year it was never there, now it shows up. Several of my friends with same year, do not have it when cycling thru the different screen options.
