Towing The controller shows gain setting, output bar graph, and trailer connectivity status in the information display. 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 if you use the manual control lever or make gain adjustments with no trailer connected. • TBC GAIN = XX.X OUTPUT Displays when you push your vehicle's brake pedal, or upon use of 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 time, 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. 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. The gain should be set to provide the maximum trailer braking assistance while making sure the trailer wheels do not lock when using the brakes. Locked trailer wheels may lead to trailer instability. 1. Make sure the trailer brakes are in good working condition, functioning normally and properly adjusted. See your trailer dealer if necessary. Hook up the trailer and make the electrical connections according to the trailer manufacturer's instructions. When you plug in a trailer with electric or electric-over-hydraulic brakes, TRAILER CONNECTED appears in the information display. Use the gain adjustment (+ and -) buttons to increase or decrease the gain setting to the desired starting point. A gain setting of 6.0 is a good starting point for heavier loads. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20-25 mph (30-40 km/h) and squeeze the manual control lever completely. If the trailer wheels lock up, indicated by squealing tires, reduce the gain setting. If the trailer wheels turn freely, increase the gain setting. Repeat Steps 5 and 6 until the gain setting is at a point just below trailer wheel lock-up. If towing a heavier trailer, trailer wheel lock-up may not be attainable even with the maximum gain setting of 10. 2. 3. 4. 5. 6. 202 F150 (TF6)
