2. Hook up the trailer and make the electrical connections according to
the trailer manufacturer’s instructions.
3. When you plug in a trailer with electric or electric-over-hydraulic
brakes, TRAILER CONNECTED appears in the information display.
4. Use the gain adjustment (+ and -) buttons to increase or decrease
the gain setting to the desired starting point. A gain setting of 6.0 is a
good starting point for heavier loads.
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 control
lever completely.
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.
Explanation of Information Display Warning Messages
Note: An authorized dealer can diagnose the trailer brake controller to
determine exactly which trailer fault has occurred. However, your Ford
warranty does not cover this diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT: Displays in response to faults
sensed by the trailer brake controller, accompanied by a single chime. If
this message appears, contact an authorized dealer as soon as possible
for diagnosis and repair. The controller may still function, but
performance may be degraded.
WIRING FAULT ON TRAILER: Displays when there is a short circuit
on the electric brake output wire. If the WIRING FAULT ON TRAILER
message displays, accompanied by a single chime, with no trailer
connected, the problem is with your vehicle wiring between the trailer
brake controller and the 7–pin connector at the bumper. 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.
