Page: 424 / 696

422 STARTING AND OPERATING
The trailer and the vehicle’s stop lamps will come on when
braking normally with the vehicle brake pedal. Only the
trailer stop lamps will come on when the manual brake
control lever is applied.
Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection status.
If no electrical connection is detected after the ignition is
turned on, pushing the GAIN adjustment button or sliding
the manual brake control lever will display the GAIN setting
for 10 seconds and the “Trailer Brake Status Indicator Light”
will not be displayed.
If a fault is detected in the trailer wiring or the Integrated
Trailer Brake Module (ITBM), the “Trailer Brake Status Indi -
cator Light” will flash.
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control power
output to the trailer brakes in 0.5 increments. The GAIN
setting can be increased to a maximum of 10 or decreased to
a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer brake control 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.
Adjusting GAIN
NOTE:
This should only be performed in a traffic free environment
at speeds of approximately 20–25 mph (30–40 km/h).
1. Make sure the trailer brakes are in good working condi
-
tion, 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.
3. When a trailer with electric/EOH brakes is plugged in,
the trailer connected message should appear in the
instrument cluster display (if the connection is not recog -
nized by the ITBM, braking functions will not be avail -
able), the GAIN setting will illuminate and the correct
type of trailer must be selected from the instrument
cluster display options.
