Explanation of Information Display Warning Messages
Note: Your TBC can be diagnosed by your authorized dealer to determine
exactly which trailer fault has occurred. However, if the fault is with the
trailer this diagnosis is not covered under your Ford warranty.
TRAILER BRAKE MODULE FAULT: Displays in response to faults sensed
by the TBC (accompanied by a single chime). If this message is displayed,
please contact your authorized dealer as soon as possible for diagnosis and
repair. The TBC may still function, but performance may be degraded.
WIRING FAULT ON TRAILER: Displays when a short circuit on the
electric brake output wire has occurred. If the WIRING FAULT ON
TRAILER message is displayed and accompanied by a single chime, with
no trailer connected, the problem is with the vehicle wiring between the
TBC to the 7–pin connector at the bumper. If the message is only displayed
with a trailer connected, the problem is related to the trailer wiring. Consult
your trailer dealer for assistance. This can be a short to ground (i.e.,
chaffed wire), short to voltage (i.e., pulled pin on trailer emergency
break-away battery) or the trailer brakes may be drawing too much current.
Points to Remember
Note: Do not attempt removal of the TBC without consulting the
Workshop Manual. Damage to the unit may result.
• Adjust GAIN setting before using the TBC for the first time.
• Adjust GAIN setting (according to procedure above) whenever road,
weather and trailer or vehicle loading conditions change from when
the GAIN was initially set.
• The manual control lever should only be used 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 TBC 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 TBC is equipped with a feature which 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 available when applying the brakes
using the vehicle’s brake pedal, not the TBC.
• The controller interacts with the brake control system and powertrain
control system of the 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 TBC
does not affect the operation of your vehicle’s brakes whether a trailer is
attached or not.
