The optional factory in-dash installed Ford Motor Company "TowCommand" integrated TBC (Trailer Brake Controller) system available and compatible on the heavy duty commercial Ford Super Duty line of trucks starting with the 2005 models.
The TowCommand TBC is made of three major components; the in-dash TBC module, a TowCommand master cylinder with a brake pressure transducer, and an activated PCM (Powertrain Control Module) parameter by a Ford dealer's NGS or WDS programming method.
Next to the TowCommand is an empty storage tray or the $85 optional 4 AUX (auxiliary) toggle switches for winches, snow plow, off-road lights, etc.
The TowCommand is covered by the standard bumper-to-bumper warranty as long as it is not discovered to be an actual trailer problem.
The TowCommand has only been verified to be compatible with trailers having electric-actuated drum brakes (one to four axles) and not hydraulic surge or electric-over-hydraulic types.
