The TBC user interface consists of

the following:

1. +/- (GAIN adjustment

buttons): Pressing these buttons

adjusts 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 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.

• 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.
