2002 FORD EXPLORER wiring

The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags).
²side air curtains (if equipped). Refer toSide air bag systemlater in
this chapter.
²one or more impact and safing sensors.
²a readiness light and tone.
²diagnostic module.
²and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
²The readiness light will either
flash or stay lit.
²The readiness light will not
illuminate immediately after
ignition is turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced at
your dealership or by a qualified technician immediately. Unless serviced,
the system may not function properly in the event of a collision.
Side air curtain system (if equipped)
Do not attempt to service, repair, or modify the air bag
Supplemental Restraint System, its fuses or the seat cover on a
seat containing an air bag. See your Ford or Lincoln Mercury dealer.

Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Never connect any trailer lighting to the vehicle's taillamp
circuits, because it may damage the electrical system resulting in
fire. Contact your local Ford dealership for assistance in proper trailer
tow wiring installation. Additional electrical equipment may be
required.
Driving while you tow
When towing a trailer:
²Ensure that you turn off your speed control. The speed control may
shut off automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
²Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide for
more information.
Trailer towing tips
²Practice 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.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be no more than 10±15% of the
loaded trailer weight.

²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) (automatic transmissions) or N (Neutral)
(manual transmissions). This aids engine cooling and air conditioner
efficiency.
²Vehicles 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
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and
²Do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions, reliability and
causing internal transmission damage.
Replace the rear axle lubricant anytime 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.
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.
Recreational towing (all wheels on the ground)
Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.

Do not replace your tires with ªhigh performanceº tires or larger
size tires.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier for the driver to lose
control and roll over.
Tires that are larger or smaller than your vehicle's original tires may also
affect the accuracy of your speedometer.
USING SNOW TIRES AND TRACTION DEVICES
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, using snow tires or traction
devices may be necessary. Ford offers tire cables as a Ford approved
accessory and recommends use of these or SAE class ªSº. See your
dealer or qualified service technician for more information on tire cables
for your vehicle.
Follow these guidelines when using snow tires and traction devices:
²Cables or chains should only be used on the rear wheels.
²Install cables or chains securely, verifying that the cables or chains do
not touch any wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the cables or chains rub or bang against
the vehicle, stop and retighten them. If this does not work, remove the
cables or chains to prevent vehicle damage.
²Avoid overloading your vehicle.
²Remove the cables or chains when they are no longer needed.
²Do not use cables or chains on dry roads.
²Do not exceed 48 km/h (30 mph) with tire cables or chains on your
vehicle.
Consult your dealer for information on other Ford approved methods of
traction control.
