If this message displays, with no trailer
connected, the problem is with your vehicle
wiring or trailer brake controller. Contact
an authorized dealer.
If the message only displays with a trailer
connected, the problem is with the trailer
wiring. Consult your trailer dealer for
assistance. This can be a short to ground
(such as a chaffed wire), short to voltage
(such as a pulled pin on trailer emergency
breakaway battery) or the trailer brakes
may be drawing too much current.
Points to Remember
Note:
Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result.
•
Adjust gain setting before using the
trailer brake controller.
•
Adjust gain setting, using the procedure
above, whenever road, weather, trailer
or vehicle loading conditions change
from when the gain was initially set.
•
Only use the manual control lever for
proper adjustment of the gain during
trailer setup. Misuse, such as
application during trailer sway, could
cause instability of trailer or tow
vehicle.
•
Avoid towing in adverse weather
conditions. The trailer brake controller
does not provide anti-lock control of
the trailer wheels. Trailer wheels can
lock up on slippery surfaces, resulting
in reduced stability of trailer and tow
vehicle.
•
The trailer brake controller is equipped
with a feature that reduces output at
vehicle speeds below 11 mph (18 km/h)
so trailer and vehicle braking is not jerky
or harsh. This feature is only active
when applying the brakes using your
vehicle's brake pedal, not the
controller.
•
The controller interacts with the brake
control system and powertrain control
system of your vehicle to provide the
best performance on different road
conditions.
•
Your vehicle's brake system and the
trailer brake system work
independently of each other. Changing
the gain setting on the controller does
not affect the operation of your
vehicle's brakes.
•
When you switch the engine off, the
controller output is disabled and the
display and module shut down.
Trailer Lamps
WARNING
Never connect any trailer lamp wiring
to the vehicle's tail lamp wiring; this
may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
