wiring FORD EXPEDITION 2020 Owners Manual

This system provides an improved overall
level of frontal crash protection to front
seat occupants and is designed to help
further reduce the risk of airbag-related
injuries. The system analyzes different
occupant conditions and crash severity
before activating the appropriate safety
devices to help better protect occupants
in a variety of frontal crash situations.
Your vehicle's Personal Safety System
consists of:
•
Driver and passenger dual-stage airbag
supplemental restraints.
• Front seat outermost seatbelts with
pretensioners, energy management
retractors and seatbelt usage sensors.
• Driver seat position sensor.
• Front passenger sensing system.
• Passenger airbag off and on indicators.
• Front crash severity sensors.
• Restraints control module with impact
and safing sensors.
• Restraint system warning light and
tone.
• The electrical wiring for the airbags,
crash sensors, seatbelt pretensioners,
front seatbelt usage sensors, driver
seat position sensor, front passenger
sensing system and indicator lights.
How Does the Personal Safety
System Work?
The Personal Safety System can adapt the
deployment strategy of the safety devices
according to crash severity and occupant
conditions. A collection of crash and
occupant sensors provides information to
the restraints control module. During a
crash, the restraints control module may
deploy the seatbelt pretensioners, one or
both stages of the dual-stage airbags
based on crash severity and occupant
conditions.

Guarding Against Exhaust Fumes
WARNING: Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods, we
recommend that you do one of the
following:
• Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
ENGINE BLOCK HEATER
(IF
EQUIPPED) WARNING:
Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING: Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING:
Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power
cable and may cause an electrical short
resulting in fire, injury and property
damage.
Note: The heater is most effective when
outdoor temperatures are below
0°F
(-18°C). The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element, installed in the engine block and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.
We recommend that you do the following
for a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• If the block heater cord is under the
hood, Do Not remove the wiring from
its original location. Do Not close the
hood on the extension wiring.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.

Some examples of conventional type
trailers are shown below.
Note:
You cannot use the system with the
types of trailers marked with the cross.
The system only works with
conventional trailers. It does not work
with other types including gooseneck
and fifth wheel. Follow the information display prompts.
Step 3: Place the Sticker on the Trailer
Frame
The supplied sticker must be placed in an
area visible by the rear view camera.
Note:
The cargo and trailer hookup lamps
turn on automatically to improve visibility.
Note: An assistant can help to carry out the
following procedure.
Note: Make sure nothing can obstruct the
rear view camera's view of the sticker. For
example, items such as a jack handle or
wiring.
Note: Position the sticker on a flat, dry and
clean horizontal surface. For best results
apply the sticker when temperatures are
above 32°F (0°C).
Note: Do not move stickers after they are
placed. Do not re-use any stickers if
removed. Note:
Additional stickers may be purchased
through your Ford Dealers parts department. Use the supplied measurement card, a
tape measure and pen to carefully mark
the area where to attach the sticker
(supplied in the back cover pocket of your
quick start guide). Make sure the whole
sticker is within the zone between the two
arcs or distance markers on the diagram,
and is also visible in the rear view camera
display.
Step 4: Take Measurements
After the sticker is correctly placed on the
trailer you must take some key
measurements.
Note:
Accurate measurements must be
taken for the system to operate properly.
Note: When rounding in inches, round
upward if the measured length is a quarter
inch or greater. Round downward if the
measured length is less than a quarter inch.
For example
12.25 in (31.11 cm) would be
rounded up to 12.50 in (31.75 cm). 12.13 in
(30.8 cm) would be rounded down to
12.00 in (30.48 cm).
Note: When rounding in centimeters, round
to the nearest whole centimeter. If the
measurement is less than
0.2 in (0.5 cm)
round downward. If the measurement is
more than or equal to 0.2 in (0.5 cm) round
upward. For example, 11.9 in (30.3 cm)
would be rounded down to
11.8 in (30 cm).
12.0 in (30.5 cm) would be rounded up to
12.2 in (31 cm).

This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE
SPEED appears in the information display.
The first thing to do is slow your vehicle
down, then pull safely to the side of the
road and check for proper tongue load and
trailer load distribution. See Towing (page
275
).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
that follows.
Note: Make sure to take into
consideration trailer frontal area.
Do not exceed 55 ft² (5.11 m²) if
your vehicle has the standard
towing package, or 60 ft² (5.57 m²)
if your vehicle has the heavy duty
package.
Note: Your vehicle could have
reduced performance when
operating at high altitudes and
when heavily loaded or towing a
trailer. When driving at elevation,
to match driving performance as
perceived at sea level, reduce gross
vehicle weight and gross
combination weight by 2% per
1,000 ft (300 m)
of elevation. Note:
Certain states require
electric trailer brakes for trailers
over a specified weight. Be sure to
check state regulations for this
specified weight. This specified
weight could limit the maximum
trailer weights, as the vehicle ’s
electrical system may not include
the wiring connector needed to
activate electric trailer brakes.
Your vehicle may tow a trailer
provided the maximum trailer
weight is less than or equal to the
maximum trailer weight listed for
your vehicle configuration on the
chart that follows.
To calculate the maximum loaded
trailer weight for your vehicle:
1. Start with the gross combined weight rating for your vehicle
model and axle ratio. See the
chart that follows.
2. Subtract all of the following
that apply to your vehicle:
•Vehicle curb weight.
• Hitch hardware weight, such
as a draw bar, ball, locks or
weight distributing.
• Driver weight.
• Passenger weight.
• Payload, cargo and luggage
weight.
• Aftermarket equipment
weight.
3. This equals the maximum
loaded trailer weight for this
combination.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer. See your scheduled
maintenance information.
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
For load specification terms found on the
tire label and Safety Compliance label and
instructions on calculating your vehicle's
load,
See Load Limit (page 269).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Trailer Towing Connector
(Vehicles with a Trailer Towing
Package and 7 –Pin Connector) When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions. Some seven-position
connectors may have the SAE J2863 logo,
which confirms that it is the proper wiring
connector and works correctly with your
vehicle.

Integrated Trailer Brake Controller (If
Equipped)
WARNING: Use the integrated
trailer brake controller to properly adjust
the trailer brakes and check all
connections before towing a trailer.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death. When used properly, the trailer brake
controller assists in smooth and effective
trailer braking by powering the trailer
’s
electric or electric-over-hydraulic brakes
with a proportional output based on the
towing vehicle ’s brake pressure.
The controller user interface consists of
the following:
A:
+ and - (Gain adjustment buttons):
Pressing these buttons adjusts the
controller's power output to the trailer
brakes in 0.5 increments. You can increase
the gain setting to 10.0 (maximum trailer
braking) or decrease it to 0 (no trailer
braking). The gain setting displays in the
message center. The controller shows gain setting, output
bar graph, and trailer connectivity status
in the information display. They appear in
the information display as follows:
•
Trailer Brake Controller Gain (without
trailer connected): Shows the current
gain setting during a given ignition cycle
and when adjusting the gain. This also
displays if you use the manual control
lever or make gain adjustments with
no trailer connected.
• Trailer Brake Controller Gain Output:
Displays when you push your vehicle's
brake pedal, or upon use of the manual
control. 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
indicate maximum output.
• Trailer Connected: Displays when the
system senses a correct trailer wiring
connection (a trailer with electric trailer
brakes) during a given ignition cycle.
• Trailer Disconnected: Displays,
accompanied by a single audible time,
when the system senses a trailer
connection and then a disconnection,
either intentional or unintentional,
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 if you use the manual control
lever without a trailer connected. After
disconnecting the trailer connector,
press the brake pedal for
approximately five seconds to allow
the system to detect and update the
trailer status.
292
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- TowingE183395

B: Manual control lever: Slide the control
lever to the left to turn on the trailer's
electric brakes independent of the tow
vehicle's. If you use the manual control
when the brake is also applied, the greater
of the two inputs determines the power
sent to the trailer brakes.
• Stop lamps: Using the manual control
lever illuminates both the trailer brake
lamps and your vehicle brake lamps
except the center high-mount stop
lamp, if you make the proper electrical
connection to the trailer. Pressing your
vehicle brake pedal also illuminates
both trailer and vehicle brake lamps.
Procedure for Adjusting Gain
Note: Only perform this procedure in a
traffic-free environment at speeds of
approximately
20– 25 mph (30–40 km/h).
The gain setting sets the trailer brake
controller for the specific towing condition.
You should change the setting 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 when
making sure the trailer wheels do not lock
when using the brakes. 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 you plug in a trailer with electric or electric-over-hydraulic brakes, a
message confirming connection
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 warranty does not cover this
diagnosis if the fault is with the trailer.
A message indicating a trailer brake
module fault may display in response to
faults sensed by the trailer brake controller,
accompanied by a single tone. 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.
A message indicating a trailer wiring fault
may display when there is a short circuit
on the electric brake output wire. If this
message displays, accompanied by a
single tone, 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
293
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Towing

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.
Points to Remember
Note:
Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result.
• Adjust gain setting before using the
trailer brake controller for the first time.
• Adjust gain setting, using the procedure
above, whenever road, weather and
trailer or vehicle loading conditions
change from when the gain was initially
set.
• Only use the manual control lever 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 trailer brake controller
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 trailer brake controller is equipped
with a feature that 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 your
vehicle's brake pedal, not the
controller.
• The controller interacts with the brake
control system and powertrain control
system of your 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 controller does
not affect the operation of your
vehicle's brakes whether you attach a
trailer or not.
• When you switch the engine off, the
controller output is disabled and the
display and module shut down. The
controller module and display turn on
when you switch the ignition on.
• The trailer brake controller is only a
factory-installed or dealer-installed
item. We are not responsible for
warranty or performance of the
controller due to misuse or customer
installation.
Trailer Lamps WARNING: Never connect any
trailer lamp wiring to the vehicle's tail
lamp wiring; this may damage the
electrical system resulting in fire. Contact
your authorized dealer as soon as
possible for assistance in proper trailer
tow wiring installation. Additional
electrical equipment may be required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, direction indicators and hazard lights
are working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
294
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201907, Third-Printing- Towing

When Towing a Trailer
•
Do not tow during the first 1,000 mi
(1,600 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine
and transmission cooling and to help
A/C performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
slopes.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• If your vehicle is equipped with
AdvanceTrac with RSC, this system
may turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed when towing may reduce
this tendency.
• If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant if the axle is not already
filled with it. See
Capacities and
Specifications (page 380). •
Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a slope. However, if
you must park on a slope:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. Chocks are not
included with your vehicle.
Your vehicle may be equipped with a
temporary or conventional spare tire. A
temporary spare tire is different in size,
tread-type, or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire
label or Safety Compliance label for
limitations when using these tires.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after removing the trailer 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.
