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.
You can adjust the amount of initial trailer
brake output by selecting one of three
settings through the message center.
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.
B: Manual control lever: Slide the control
lever to the left to switch on the trailer's
electric brakes independent of the tow
vehicle's. See the following Procedure for
adjusting gain section for instructions on
proper use of this feature. If you use the
manual control while the brake is also
applied, the greater of the two inputs
determines the power sent to the trailer
brakes.
• Stop lamps: Using the manual control
lever lights both the trailer brake lamps
and your vehicle brake lamps except
the center high-mount stop lamp, if
you make the proper electrical
connection to the trailer. Pressing your
vehicle brake pedal also lights both
trailer and vehicle brake lamps.
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.
• TBC GAIN = XX.X OUTPUT=/ / / /
/ /: Displays when you push your
vehicle's brake pedal, or upon use of
the manual control. Bar indicators light
in the information display to indicate
the amount of power going to the
trailer brakes relative to the brake
pedal or manual control input. One bar
indicates the least amount of output;
six bars indicate maximum output.
