Ford TowCommand
From Wikipedia, the free encyclopedia
The $230 optional Ford Motor Company "TowCommand" integrated TBC (Trailer Brake Controller) is only available and compatible on the extra-heavy duty commercial Ford Super Duty line of trucks starting with the 2005 models. It is built and engineered jointly with Tekonsha who is famous for their Prodigy TBC. With adjustable +/- trailer braking gain in a digital readout from 0.0 (no trailer brakes) to 10.0 (full trailer braking) in 0.5 increments and a manual override lever (to test trailer braking action), the Ford 'built into the dash' TBC provides smooth braking even when pulling a 15,000 lb triple axle conventional trailer. TowCommand being different from most aftermarket TBCs, ties into the trucks' computer and hydraulics, so it senses truck brake pressure and can apply trailer brakes as fast as the truck's brakes. Master Brake Systems 'BrakeSmart' TBC is the only other one that taps into the trucks hydraulic lines in modern trucks.
The TowCommand TBC is basically made of three major components; the in-dash TBC module, a special 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. All 2005 and newer Ford Super Duty trucks are already pre-wired for the TBC from the factory, no matter if the TBC option was ordered and installed at the time of the trucks assembly or not.
Before ABS (Anti-lock Braking System) came to trucks in the 1980s, most TBCs were activated by the trucks' brake hydraulic action. In an emergency situation with the trucks ABS activated, Ford's TowCommand can automatically reduce the trailer brake pressure (gain) as it communicates with the truck's computer for faster reaction time with proportional trailer brake control, to prevent the trailer brakes from locking up even though trailers do not have ABS sensors. TowCommand will also tell you with an audible alarm and in the digital readout if your trailer wires and/or trailer disconnects from the truck. All these features will make towing a trailer in heavy traffic less hectic also. Next to the TowCommand is an empty storage tray or the $85 optional 4 AUX (auxiliary) toggle switches you can use for winches, snow plow, off-road lights, etc.
The only disadvantage, unlike aftermarket TBCs, you can not transfer it from one truck to the next. Another advantage, unlike aftermarket TBCs, you can pull into any Ford service center when on the road and have it serviced. The TowCommand is even covered by the standard bumper-to-bumper warranty as long as it is not discovered to be an actual trailer problem. TowCommand only works with trailers containing electric brakes with one to four axles.
