FORD 2013 F-550 v.3 - Manual (Page 260)

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). Pressing and holding a button raises
or lowers the setting continuously. 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
information display as follows:
• TBC GAIN = XX.X NO TRAILER: Shows the current gain setting
during a given ignition cycle and when adjusting the gain. This also
displays if you use the manual control lever or make gain adjustments
with no trailer connected.
