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 condi-
tion and should be changed as towing condi-
tions change. Changes to towing conditions
include trailer load, vehicle load, road condi-
tions 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 condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
2. Hook up the trailer and make the electri-
cal 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 available), the GAIN setting will
illuminate and the correct type of trailer
must be selected from the instrument
cluster display options.
4. Push the UP or DOWN button on the
steering wheel until "TRAILER TOW" ap-
pears on the screen.
5. Push the RIGHT arrow on the steering
wheel to enter "TRAILER TOW".
6. Push the UP or DOWN buttons until the
Trailer Brake Type appears on the screen.
7. Push the RIGHT arrow and then push the
UP or DOWN buttons until the proper
Trailer Brake Type appears on the screen.
8. In a traffic-free environment, tow the
trailer on a dry, level surface at a speed of
20–25 mph (30–40 km/h) and squeeze
the manual brake control
completely.
9. If the trailer wheels lockup (indicated by
squealing tires), reduce the GAIN setting;
if the trailer wheels turn freely, increase
the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting
is at a point just below trailer wheel lockup. If
towing a heavier trailer, trailer wheel lockup
may not be attainable even with the maxi-
mum GAIN setting of 10.
