Points to Remember:
•Remember to adjust gain setting before using the TBC for the first
time.
•Readjust GAIN setting on the TBC (according to procedure above)
whenever road, weather and trailer or vehicle loading conditions
change from those that existed when the gain was initially set.
•The sliding lever on the TBC should be used only for manual
activation of trailer brakes to assist with proper adjustment of the
GAIN. Misuse, such as application during trailer sway, could cause
instability of trailer and/or tow vehicle.
•Avoid towing in adverse weather conditions. The TBC does not
provide anti-lock control of the trailer wheels. Trailer wheels can
lock-up on slippery surfaces, resulting in reduced stability of trailer
and tow vehicle.
•The TBC interacts with the brake system of the vehicle, including
ABS, in order to reduce the likelihood of trailer wheel lockup.
Therefore, if these systems are not functioning properly the TBC may
not function at full performance.
•When the vehicle is turned off, the TBC Output is disabled and the
display is shut down. Reactivation of the ignition from 3 (OFF) to 4
(ON) will awaken the TBC module.
•The TBC is only a factory or dealer installed item. Ford is not
responsible for warranty or performance of the TBC due to misuse or
customer installation.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See your
authorized dealer or trailer rental agency for proper instructions and
equipment for hooking up trailer lamps.
Using a step bumper (if equipped)
The rear bumper is equipped with an integral hitch and only requires a
ball with a one inch (25.4 mm) shank diameter. The bumper has a 5,000 lb.
(2,270 kg) trailer weight and 500 lb. (227 kg) tongue weight capacity.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
