The trailer brake controller (TBC) is designed to display three items of
information in the instrument cluster message center. These are: gain
setting, output bar graph, and trailer connectivity status. They appear in
the message center as follows:
•TBC GAIN = XX.X NO TRAILER:The instrument cluster message
center displays the current gain setting during a given ignition cycle
and when adjusting the gain. This message is also displayed during
manual activation without a trailer connected or when gain
adjustments are made with no trailer connected.
•TBC GAIN = XX.X OUTPUT = //////:When the vehicle’s brake pedal
is pushed, or when the manual control is activated, bar indicators
illuminate in the instrument cluster message center to indicate the
amount of power going to the trailer brakes relative to the brake pedal
or manual control input. One bar indicates the least amount of output
with six bars indicating maximum output.
•TRAILER CONNECTED:This message is displayed when a correct
trailer wiring connection (a trailer with electric trailer brakes) has
been sensed during a given ignition cycle.
•TRAILER DISCONNECTED:This message is displayed and
accompanied by a single chime, when a trailer connection was
determined and then a disconnection, either intentionally or
unintentionally, has been sensed during a given ignition cycle. It is also
displayed if a truck or trailer wiring fault occurs causing the trailer to
appear disconnected. This message is also displayed during manual
activation without a trailer connected.
2.Manual control lever:Slide the control lever to the left to activate
power to the trailer’s electric brakes independent of the tow vehicle’s
brakes (see the followingProcedure for adjusting GAINsection for
instructions on proper use of this feature). If the manual control is
activated while the brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
•Stop lamps:Activating the TBC manual control lever illuminates both
the trailer brake lamps and the tow vehicle brake lamps except the
center high-mount stop lamp (presuming proper trailer electrical
connection). Pressing the vehicle brake pedal also illuminates both
trailer and vehicle brake lamps.

WIRING FAULT ON TRAILER:This message is displayed when a
Short circuit on the electric brake output wirehas occurred. If the
WIRING FAULT ON TRAILERmessage 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 isnotcovered 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.

Trailer towing tips
•Practice turning, stopping and backing-up before starting on a trip to
get the feel of the vehicle-trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective. Also, see the information on tow/haul mode operation
underAutomatic transmission operationin theDrivingchapter.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full throttle starts.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•Do not allow the static water level to rise above the bottom edge of
the rear bumper.
•Do not allow waves to break higher than 6 in (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•Causing internal damage to the components.
•Affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
