Ford F-150 Owner's Manual page 278

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.
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.
• TBC GAIN = XX.X OUTPUT = / / / / / /: Displays when you push
your vehicle's brake pedal, or when you use the manual control. Bar
indicators illuminate 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.
• TRAILER CONNECTED: Displays when the system senses a
correct trailer wiring connection (a trailer with electric trailer brakes)
during a given ignition cycle.
