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 a 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.
4.
Push the UP or DOWN button on the steering wheel
until "TRAILER TOW" appears 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 lever 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
maximum GAIN setting of 10.
Display Messages
The trailer brake control interacts with the instrument
cluster display. Display messages, along with a single
chime, will be displayed when a malfunction is determined
in the trailer connection, trailer brake control, or on the
trailer

WARNING!
Connecting a trailer that is not compatible with the
ITBM system may result in reduced or complete loss of
trailer braking. There may be an increase in stopping
distance or trailer instability which could result in
personal injury.
CAUTION!
Connecting a trailer that is not compatible with the
ITBM system may result in reduced or complete loss of
trailer braking. There may be an increase in stopping
distance or trailer instability which could result in
damage to your vehicle, trailer, or other property.
STARTING AND OPERATING
NOTE:
An aftermarket controller may be available for use with
trailers with air or EOH trailer brake systems. To deter-
mine the type of brakes on your trailer and the avail-
ability of controllers, check with your trailer
manufacturer or dealer.
Removal of the ITBM will cause errors and it may cause
damage to the electrical system and electronic
modules of the vehicle. See an authorized dealer if an
aftermarket module is to be installed.
Towing Requirements — Trailer Lights And
Wiring
Whenever pulling a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:
Do not cut or splice wiring into the vehicle's wiring
harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.
NOTE:
Disconnect the trailer wiring connector from the vehicle
(or any other device plugged into vehicle's electrical
connectors) before launching a boat into water.
Be sure to reconnect once clear from water area.
