FORD 2012 F-150 Raptor v.3 - Manual (Page 277)

Trailer Brakes
WARNING: Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not
have enough braking power and your chances of having a collision
greatly increase.
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and federal regulations.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Integrated trailer brake controller (if equipped)
Your vehicle may be equipped with a fully integrated electronic trailer
brake controller (TBC). When used properly, the TBC helps ensure
smooth and effective trailer braking by powering the trailer’s electric
brakes with a proportional output based on the towing vehicle’s brake
pressure.
WARNING: The Ford TBC has only been verified to be
compatible with trailers having electric-actuated drum brakes
(one to four axles) and not hydraulic surge or electric-over-hydraulic
types. 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.
The TBC user interface consists of
the following:
1. +/- (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.
