STARTING AND OPERATING
Integrated Trailer Brake Module (ITBM) —
If Equipped
Your vehicle may have an ITBM for Electric and
Electric Over Hydraulic (EOH) trailer brakes.
NOTE:
This module has been designed and verified with
electric trailer brakes and new electric over
hydraulic systems. Some previous EOH systems
may not be compatible with ITBM.
Integrated Trailer Brake Module (ITBM)
The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to
activate power to the trailer's electric brakes
independent of the tow vehicle's brakes. If the
manual brake control lever is activated while the
brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
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 Disconnected Warning Light will not be
displayed.
If a fault is detected in the trailer wiring or the ITBM,
the Trailer Brake Disconnected Warning 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 envi
-
ronment 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 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 recognized 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.
