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 connec-
tions according to the trailer manufacturer’s instructions.
3. When a trailer with electric/EOH brakes is plugged
in, the GAIN setting will illuminate and the correct type
of trailer must be selected from the EVIC options (refer to
“Electronic Vehicle Information Center/Programmable
Features” in “Understanding Your Instrument Panel” for
further information).
4. Use the GAIN adjustment (+/-) buttons to increase or
decrease the GAIN setting to the desired starting point. A
GAIN setting of 5 is a good starting point.
5. 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.
6. 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 5 and 6 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.
EVIC Display Messages
The trailer brake control interacts with the Electronic
Vehicle Information Center (EVIC). 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. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
