Tires, Wheels and Loading 3. GAIN setting display: Shows the current GAIN setting. This will illuminate when a trailer is connected, flash if the trailer becomes disconnected, or remain off if no trailer is connected. 4. +/- (GAIN adjustment buttons): Pressing these buttons will adjust 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 will raise or lower the setting continuously. Continued pressing of a gain button for five seconds after reaching a limit will reset the gain to the previous setting. 5. 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 Procedure for adjusting GAIN section following 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 TBC manual control lever will illuminate both the trailer brake lamps and the tow vehicle brake lamps except the Center High-Mount Stop Lamp (presuming proper trailer electrical connection). Pressing the vehicle brake pedal will also illuminate both trailer and vehicle brake lamps. GAIN: 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 ensuring the trailer wheels do not lock when braking. Locked trailer wheels may lead to trailer instability. 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). 1. Make sure the trailer brakes are in good working condition, functioning normally, and properly adjusted. See your trailer dealer if necessary. 2. Hook up the trailer and make the electrical connections according to the trailer manufacturer's instructions. 3. When a trailer with electric brakes is plugged in, the trailer connection indicator will illuminate blue on the TBC and the GAIN setting display will illuminate. 259 2009 F-150 (f12) Owners Guide (own2002), 3rd Printing USA (fus)
