1999 FORD RANGER wiring

The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags),
²one or more impact and safing sensors, passenger air bag deactivation
switch and diagnostic monitor (RCM)
²a readiness light and tone
²and the electrical wiring which connects the components.
The RCM (restraints control module) monitors its own internal circuits
and the supplemental air bag electrical system warning (including the
passenger air bag deactivation switch, 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 readiness lights in the instrument cluster and the
passenger air bag deactivate switch or a tone to indicate the condition of
the system. Refer to theAir bag readinesssection in the
Instrumentationchapter orPassenger air bag deactivate switch
section in this chapter. 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 lights will either
flash or stay lit.
²The readiness lights 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 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.
Disposal of air bags and air bag equipped vehicles
For disposal of air bags or air bag equipped vehicles, see your local
dealership or qualified technician. Air bags MUST BE disposed of by
qualified personnel.

Trailer towing tips
²Practice turning, stopping and backing up in an area 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 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 (six 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).
Driving
130

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.
SNOW TIRES AND CHAINS
Driving too fast for conditions creates the possibility of loss of
vehicle control. Driving at very high speeds for extended periods
of time may result in damage to vehicle components.
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, you may need to use snow
tires and chains. If you need to use snow tires and chains,it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.
Follow these guidelines when using snow tires and chains:
²Do not use tire chains on aluminum wheels. Chains may chip the
wheels.
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
