Trailer Tow

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. 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 -- F250-F550 SUPER DUTY .

On vehicles not equipped with a factory manufactured TBC module, the vehicle comes equipped with circuitry to support an aftermarket TBC module.
