+ and - (Gain adjustment buttons):
Pressing these buttons adjusts the
controller's power output to the trailer
brakes in 0.5 increments. You can increase
the gain setting to 10.0 (maximum trailer
braking) or decrease it to 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

Manual control lever: Slide the control
lever to the left to switch on the trailer's
electric brakes independent of the tow
vehicle's. See the following

determines the power sent to the trailer
brakes.

lever lights both the trailer brake lamps
and your vehicle brake lamps.

Procedure for Setting Trailer Brake
Controller Effort
See
General Information
(page 88).
Choose either the electric option for trailers
with electromagnetic drum brakes, or the
electric over hydraulic option for trailers
with these brake systems.
Trailer Brake Effort Setting
The trailer brake controller allows the user
to customize how aggressively the trailer
brakes engage. The default value is the low
setting and is the recommended setting
for most trailers. If your trailer's brakes
require more initial voltage, or if you prefer
more aggressive trailer braking, then select
either the medium or the high setting.
Procedure for Setting Trailer Brake
Controller Mode
See
General Information
(page 88).
Choose the low, medium or high setting
for the required initial trailer brake output.
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 adjusts 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.
2. Hook up the trailer and make the
electrical connections according to the
trailer manufacturer's instructions.
