Trailer Tow
WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The trailer tow system consists of the following components:
- Trailer tow connector
- Trailer tow relays
- Trailer Brake Control (TBC) module
The Battery Junction Box (BJB) supplies voltage to the trailer tow stop/turn, parking and reversing lamps. When the vehicle's rear stop/turn, parking lamps or reversing are illuminated, voltage is also supplied to a corresponding trailer tow relay located in the BJB.
The trailer tow battery charge relay provides voltage to the trailer tow connector when the ignition switch is in the RUN position.
The vehicle can be equipped with a factory manufactured TBC module. For diagnostic information, refer to AUXILIARY BRAKE SYSTEM .
On vehicles not equipped with a factory manufactured TBC module, the vehicle comes equipped with circuitry to support an aftermarket TBC module.
