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.

• 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 illuminates 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 also illuminates both

trailer and vehicle brake lamps.
