Towing 255 – FORD 2013 F-550 v.1 User Manual
Page 256
The Ford TBC has been tested to be compatible with several major
brands of electric-over-hydraulic trailer brakes; contact your authorized
dealer for information on which brands can be used.
The TBC user interface consists of the following:
A. +/- (GAIN adjustment buttons): Pressing these buttons adjusts the
TBC’s power output to the trailer brakes (in 0.5 increments). The GAIN
setting can be increased to a maximum of 10.0 or decreased to a
minimum of 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 is designed to display three items of information in the
information display. These are: GAIN setting, output bar graph, and trailer
connectivity status. 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 during manual activation without a trailer connected or when
GAIN adjustments are made with no trailer connected.
• 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.
