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 ad-
justed. See your trailer dealer if necessary.
2. Hook up the trailer and make the electrical connec-
tions according to the trailer manufacturer’s instruc-
tions.
3. When a trailer with electric/EOH brakes is plugged
in, the trailer connected message should appear in the
EVIC/DID (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 EVIC/DID 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 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 com-
pletely.
9. If the trailer wheels lockup (indicated by squealing
tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
