FORD 2013 F-150 v.1 - Manual (Page 269)

• TBC GAIN = XX.X OUTPUT = / / / / / /: Displays when the vehicle’s
brake pedal is pushed, or when the manual control is activated. 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 indicates maximum output.
• TRAILER CONNECTED: Displays when a correct trailer wiring
connection (a trailer with electric trailer brakes) has been sensed
during a given ignition cycle.
• TRAILER DISCONNECTED: Displays, accompanied by a single
audible chime, when a trailer connection was determined and then a
disconnection (either intentionally or unintentionally), has been
sensed during a given ignition cycle. It also displays if a truck or
trailer wiring fault occurs causing the trailer to appear disconnected.
This message can also display during manual activation without a
trailer connected.
B. Manual control lever: Slide the control lever to the left to activate
power to the trailer’s electric brakes independent of the tow vehicle’s
brakes (see the following Procedure for adjusting GAIN section for
instructions on proper use of this feature). If the manual control is
activated while the brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
• Stop lamps: Activating the manual control lever illuminates both the
trailer brake lamps and the tow vehicle brake lamps except the
center high-mount stop lamp (if the proper electrical connection has
been made to the trailer). Pressing the vehicle brake pedal also
illuminates both trailer and vehicle brake lamps.
Procedure for Adjusting GAIN
Note: This should only be performed in a traffic-free environment at
speeds of approximately 20–25 mph (30–40 km/h).
The GAIN setting is used to set the TBC for the specific towing
condition and should be changed as towing conditions change. Changes
to towing conditions include trailer load, vehicle load, road conditions
and weather.
The GAIN should be set to provide the maximum trailer braking
assistance while making sure the trailer wheels do not lock when
braking. Locked trailer wheels may lead to trailer instability.
1. Make sure the trailer brakes are in good working condition,
functioning normally and properly adjusted. See your trailer dealer if
necessary.
