Tires, Wheels and Loading WIRING FAULT ON TRAILER: This message is displayed 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 from 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) or a short to voltage (i.e., pulled pin on trailer emergency break-away battery) or trailer brakes drawing too much current. 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. Points to Remember: • Remember to adjust gain setting before using the TBC for the first time. • Readjust gain setting on the TBC (according to procedure above) whenever road, weather and trailer or vehicle loading conditions change from those that existed when the gain was initially set. • The sliding lever on the TBC should be used only for manual activation of trailer brakes to assist with proper adjustment of the GAIN. Misuse, such as application during trailer sway, could cause instability of trailer and/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 TBC interacts with the brake system of the vehicle, including ABS, in order to reduce the likelihood of trailer wheel lock-up; therefore, if these systems are not functioning properly, the TBC may not function at full performance. • 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. 182 2011 Econoline (eco) Owners Guide, 3rd Printing USA (fus)

WIRING FAULT ON TRAILER:
This message is displayed 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 from 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) or a short to voltage (i.e., pulled
pin on trailer emergency break-away battery) or trailer brakes drawing
too much current.
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.
Points to Remember:
Remember to adjust gain setting before using the TBC for the first
time.
Readjust gain setting on the TBC (according to procedure above)
whenever road, weather and trailer or vehicle loading conditions
change from those that existed when the gain was initially set.
The sliding lever on the TBC should be used only for manual
activation of trailer brakes to assist with proper adjustment of the
GAIN. Misuse, such as application during trailer sway, could cause
instability of trailer and/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 TBC interacts with the brake system of the vehicle, including
ABS, in order to reduce the likelihood of trailer wheel lock-up;
therefore, if these systems are not functioning properly, the TBC may
not function at full performance.
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.
