Procedure for adjusting gain, 260 towing – FORD 2013 F-550 v.3 User Manual
Page 261
• 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.
• TRAILER DISCONNECTED: Displays, accompanied by a single
audible chime, when the system senses a trailer connection and then
a disconnection, either intentional or unintentional, 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 if you use the manual control lever without a trailer
connected.
B. Manual control lever: Slide the control lever to the left to turn
on 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 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 illuminates 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 illuminates both
trailer and vehicle brake lamps.
Procedure for Adjusting Gain
Note: Only perform this procedure in a traffic-free environment at
speeds of approximately 20–25 mph (30–40 km/h).
The gain setting sets the trailer brake controller for the specific towing
condition. You should change the setting as towing conditions change.
Changes to towing conditions include trailer load, vehicle load, road
conditions and weather.
