Integrated Trailer Brake Controller
6. If the trailer wheels lock up, 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 lock-up.
If towing a heavier trailer, trailer wheel
lock-up may not be attainable even
with the maximum gain setting of 10.
Note: Only perform this procedure at
speeds of approximately 20–25 mph
(30–40 km/h).
Note: The trailer brake controller reduces
output at vehicle speeds below 11 mph
(18 km/h) so that trailer and vehicle braking
is not jerky or harsh. This feature is only
available when applying the brakes using
your vehicle's brake pedal, not the
controller.
Note: 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 whether you attach a
trailer or not.
Note: With the proper electrical connection,
pressing your vehicle brake pedal or using
the manual control lever illuminates both
trailer and vehicle brake lamps.
Note: When you switch the engine off, the
controller output is disabled and the display
and module shut down. The controller
module and display turn on when you switch
the ignition on.
