Tires, Wheels and Loading 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 will 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. • TRAILER DISCONNECTED: This message is displayed and accompanied by a single chime, when a trailer connection was determined and then a disconnection, either intentionally or unintentionally, has been sensed during a given ignition cycle. It is also displayed if a truck or trailer wiring fault occurs causing the trailer to appear disconnected. This message is also displayed during manual activation without a trailer connected. 2. 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 the following Procedure for adjusting GAIN section 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. Procedure for adjusting 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. Note: This should only be performed in a traffic free environment at speeds of approximately 20-25 mph (30-40 km/h). 188 2009 Econoline (eco) Owners Guide, 2nd Printing USA (fus)
