2013 FORD F150 brakes

GCW (Gross Combined Weight)– is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating)– is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicle’s braking system is rated for operation at
GVWR, not at GCWR.) Separate functional brakes should be used for
safe control of towed vehicles and for trailers where the GCW of the
towing vehicle plus the trailer exceed the GVWR of the towing vehicle.
The GCW must never exceed the GCWR.
Maximum Loaded Trailer Weight– is the highest possible weight of a
fully loaded trailer the vehicle can tow. It assumes a vehicle with only
mandatory options, no cargo (internal or external), a tongue load of
10–15% (conventional trailer) or king pin weight of 15–25% (fifth wheel
trailer), and driver only (150 lb. [68 kg]).Consult your authorized
dealer (or theRV and Trailer Towing Guideprovided by your
authorized dealer) for more detailed information.
Tongue Load or Fifth Wheel King Pin Weight– refers to the amount
of the weight that a trailer pushes down on a trailer hitch.
Examples:For a 5,000 lb. (2,268 kg) conventional trailer, multiply 5,000
by 0.10 and 0.15 to obtain a proper tongue load range of 500 to 750 lb.
(227 to 340 kg). For an 11,500 lb. (5,216 kg) fifth wheel trailer, multiply
by 0.15 and 0.25 to obtain a proper king pin load range of 1,725 to
2,875 lb. (782 to 1,304 kg)
WARNING:Do not exceed the GVWR or the GAWR specified on
the Safety Compliance Certification Label.

TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Note:For information on electrical items such as fuses or relays, see the
Fuseschapter.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components periodically during, and after, any towing operation.
Load Placement
To help minimize how trailer movement affects the vehicle when driving:
•Load the heaviest items closest to the trailer floor.
•Load the heaviest items so they are centered between the left and
right side trailer tires.
•Load the heaviest items above the trailer axles or just slightly forward
toward the trailer tongue. Do not allow the final trailer tongue weight
to go above or below 10–15% of the loaded trailer weight.
•Select a tow bar with the correct rise or drop. When both the loaded
vehicle and trailer are connected, the trailer frame should be level, or
slightly angled down toward the vehicle, when viewed from the side.
When driving with a trailer or payload, a slight takeoff vibration or
shudder may be present due to the increased payload weight. Additional
information regarding proper trailer loading and setting your vehicle up
for towing is noted underLoad limitin theLoad Carryingchapter and
in theRV & Trailer Towing Guide,available at your authorized dealer.

TRAILER SWAY CONTROL (IF EQUIPPED)
Note:This feature does not prevent trailer sway, but reduces it once it
begins.
Note:This feature cannot stop all trailers from swaying.
Note:In some cases, if vehicle speed is too high, the system may
activate multiple times, gradually reducing vehicle speed.
This feature applies the vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the
stability control light flashes and the messageTRAILER SWAY
REDUCE SPEEDappears in the information display. The first thing to
do is slow the vehicle down, then pull safely to the side of the road and
check for proper tongue load and trailer load distribution. See theLoad
Carryingchapter for specific loading information.
RECOMMENDED TOWING WEIGHTS
Note:Do not exceed a trailer weight of 5000 pounds (2268 kilograms)
when towing with, or by, bumper only.
Note:Do not exceed a trailer weight of 5000 pounds (2268 kilograms) if
your vehicle is not equipped with a Heavy-duty Trailer Towing Package.
Note:Trailer frontal area is the total area in square feet (meters) that a
moving vehicle and trailer are exposed to air resistance. The following
trailer frontal area limitations should be considered in selecting a trailer
based on your vehicle configuration:
•Equal to the base vehicle frontal area on vehicles without the Trailer
Tow Package or the Heavy Duty Payload Package.
•60 feet
2(5.57 meters2) on vehicles with the Trailer Tow Package or
the Heavy Duty Payload Package.
Note:Exceeding these limitations may significantly reduce the
performance of your towing vehicle. Selecting a trailer with a low
aerodynamic drag and rounded front design will help optimize
performance and fuel economy.
Note:For high altitude operation, reduce the gross combined weight by
2% per 1000 feet (300 meters) starting at the 1000 foot (300 meter)
elevation point.
Note:Certain states require electric trailer brakes for trailers over a
specified weight. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as the vehicle’s electrical system may not include the
wiring connector needed to activate electric trailer brakes.

When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park the loaded vehicle (without the trailer) on a level surface.
2. Measure the height to the top of the vehicle front wheel opening on
the fender, this is H1.
3. Securely attach the loaded trailer to the vehicle without the
weight-distributing bars connected.
4. Measure the height to the top of the vehicle front wheel opening on
the fender a second time, this is H2.
5. Install and adjust the tension in the weight-distributing bars so that
the height of the vehicle’s front wheel opening on the fender is
approximately halfway between H1 and H2.
6.
Check that the trailer is level or slightly nose down toward the vehicle.
If not, adjust the ball height accordingly and repeat Steps 1–6.
7. Lock bar tension adjuster in place.
8. Check that the trailer tongue is securely attached and locked to the
hitch.
9. Install safety chains, lighting, and trailer brake controls as required by
law or the trailer manufacturer.
Safety Chains
Note:Do not attach safety chains to the bumper.
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch.
To connect the trailer’s safety chains, cross the chains under the trailer
tongue and allow enough slack for turning tight corners. Do not allow the
chains to drag on the ground.
Trailer Brakes
WARNING:Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not have
enough braking power and your chances of having a collision greatly
increase.
Electric brakes and manual, automatic or surge-type trailer brakes are safe
if installed properly and adjusted to the manufacturer’s specifications. The
trailer brakes must meet local and Federal regulations.
The braking system of the tow vehicle is rated for operation at
the GVWR not GCWR.
Separate functioning brake systems are required for safe control
of towed vehicles and trailers weighing more than 1500 pounds
(680 kilograms) when loaded.

Integrated Trailer Brake Controller (If Equipped)
WARNING:The Ford TBC has only been verified to be
compatible with trailers having electric-actuated drum brakes
(one to four axles) and some electic-over-hydrualic (EOH) brakes. It
will not activate hydraulic surge-style trailer brakes. It is the
responsibility of the customer to ensure that the trailer brakes are
adjusted appropriately, functioning normally and all electric connections
are properly made. Failure to do so may result in loss of vehicle
control, crash or serious injury.
When used properly, the TBC assists in smooth and effective trailer
braking by powering the trailer’s electric or EOH brakes with a
proportional output based on the towing vehicle’s brake pressure.
The TBC user interface consists of the following:
A.+/- (GAIN adjustment buttons):Pressing these buttons adjusts the
TBC’s power output to the trailer brakes (in 0.5 increments). The GAIN
setting can be increased to a maximum of 10.0 or decreased to a
minimum of 0 (no trailer braking). Pressing and holding a button raises
or lowers the setting continuously. The GAIN setting displays in the
message center as follows: TBC GAIN = XX.X.
The controller is designed to display three items of information in the
information display. These are: GAIN setting, output bar graph, and
trailer connectivity status. They appear in the information display as
follows:
•TBC GAIN = XX.X NO TRAILER:Shows the current GAIN setting
during a given ignition cycle and when adjusting the GAIN. This also
displays during manual activation without a trailer connected or when
GAIN adjustments are made with no trailer connected.

•TBC GAIN = XX.X OUTPUT=//////:Displays when the vehicle’s
brake pedal is pushed, or when the manual control is activated. Bar
indicators illuminate in the information display 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;
six bars indicates maximum output.
•TRAILER CONNECTED:Displays when a correct trailer wiring
connection (a trailer with electric trailer brakes) has been sensed
during a given ignition cycle.
•TRAILER DISCONNECTED:Displays, accompanied by a single
audible chime, when a trailer connection was determined and then a
disconnection (either intentionally or unintentionally), has been
sensed during a given ignition cycle. It also displays if a truck or
trailer wiring fault occurs causing the trailer to appear disconnected.
This message can also display during manual activation without a
trailer connected.
B.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 manual control lever illuminates both the
trailer brake lamps and the tow vehicle brake lamps except the
center high-mount stop lamp (if the proper electrical connection has
been made to the trailer). Pressing the vehicle brake pedal also
illuminates both trailer and vehicle brake lamps.
Procedure for Adjusting GAIN
Note:This should only be performed in a traffic-free environment at
speeds of approximately 20–25 mph (30–40 km/h).
The GAIN setting is used to set the TBC for the specific towing
condition and should be changed as towing conditions change. Changes
to towing conditions include trailer load, vehicle load, road conditions
and weather.
The GAIN should be set to provide the maximum trailer braking
assistance while making sure the trailer wheels do not lock when
braking. Locked trailer wheels may lead to trailer instability.
1. Make sure the trailer brakes are in good working condition,
functioning normally and properly adjusted. See your trailer dealer if
necessary.

2. Hook up the trailer and make the electrical connections according to
the trailer manufacturer’s instructions.
3. When a trailer with electric or EOH brakes is plugged in, TRAILER
CONNECTED appears in the information display.
4. Use the GAIN adjustment (+/-) 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: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.
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 theWIRING FAULT ON
TRAILERmessage 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.
•When the vehicle is turned off, the TBC output is disabled and the
display and module are shut down. The TBC module and display turn
on when the ignition is turned from the off position to the on
position.
•The TBC is only a factory-installed or dealer-installed item. Ford is
not responsible for warranty or performance of the TBC due to
misuse or customer installation.
Trailer Lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking up the lamps.
