Trailer Brake Controller-Integrated - Ford 2015 EXPEDITION Owner's Manual

The rating for the tow vehicle's braking system operation is at the
gross vehicle weight rating, not the gross combined weight rating.
Separate functioning brake systems are required for safe control
of towed vehicles and trailers weighing more than 1500 pounds
(680 kilograms) when loaded.
Integrated Trailer Brake Controller (If Equipped)
WARNING: The Ford TBC has been verified to be compatible
with trailers having electric-actuated drum brakes (one to four
axles) and some electric-over-hydraulic (EOH) brakes. It will not
activate hydraulic surge-style trailer brakes. It is the responsibility of
the customer to ensure that the trailer brakes are adjusted
appropriately, functioning normally and all electric connections are
properly made. Failure to do so may result in loss of vehicle control,
crash or serious injury.
When used properly, the trailer brake controller assists in smooth and
effective trailer braking by powering the trailer's electric or
electric-over-hydraulic brakes with a proportional output based on the
towing vehicle's brake pressure.
Ford has tested the trailer brake controller to be compatible with several
major brands of electric-over-hydraulic trailer brakes. Contact an
authorized dealer for information on which brands you can use.
The controller user interface consists of the following:
A. + and - (Gain adjustment buttons): Pressing these buttons adjusts
the controller's power output to the trailer brakes in 0.5 increments. You
can increase the gain setting to 10.0 (maximum trailer braking) or
decrease it to 0 (no trailer braking). The gain setting displays in the
message center as follows: TBC GAIN = XX.X.
The controller shows gain setting, output bar graph, and trailer
connectivity status in the information display. They appear in the
