Tires, Wheels and Loading 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: TRAILER BRAKE 1. +/- (GAIN adjustment buttons): Pressing these buttons + adjusts the TBC's power output to the trailer brakes (in 1 0.5 increments). The GAIN setting 2 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 trailer brake controller (TBC) is designed to display three items of information in the instrument cluster message center. These are: gain setting, output bar graph, and trailer connectivity status. They appear in the message center as follows: • TBC GAIN = XX.X NO TRAILER: The instrument cluster message center displays the current gain setting during a given ignition cycle and when adjusting the gain. This message is also displayed during manual activation without a trailer connected or when gain adjustments are made with no trailer connected. • TBC GAIN = XX.X OUTPUT = //////: When the vehicle's brake pedal is pushed, or when the manual control is activated, bar indicators illuminate in the instrument cluster message center 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 with six bars indicating maximum output. • TRAILER CONNECTED: This message is displayed when a correct trailer wiring connection (a trailer with electric trailer brakes) has been sensed during a given ignition cycle. 278 2012 F-150 (f12) Owners Guide, 2nd Printing USA (fus)
