ECU FORD EXPLORER 2002 3.G Owners Manual

TheService Engine Soonindicator light illuminates when the ignition is
first turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the Service Engine Soon light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourService Engine Soonlight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the gas cap. After three driving cycles
without these or any other temporary malfunctions present, theService
Engine Soonlight should turn off. (A driving cycle consists of a cold
engine startup followed by mixed city/highway driving.) No additional
vehicle service is required.
If theService Engine Soonlight remains on, have your vehicle serviced
at the first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.

provides a convenient way to replace up to three hand-held transmitters
with a single built-in device. This feature will learn the radio frequency
codes of most current transmitters to operate garage doors, entry gates,
security systems, entry door locks, and home or office lighting.
When programming your HomeLinktUniversal Transceiver, to a
garage door or gate be sure that people and objects are out of
the way to prevent potential harm or damage.

luggage compartment of your vehicle.
To install the shade:
1. Fasten the cover into the
mounting brackets (make sure the
cover is right side up).
2. Pull the end of the shade toward
you and hook the sides into the
notches (right side first) in the rear
trim panels.
To prevent the possibility of
injuries, the fasteners for
the cargo area cover must be
properly attached to the mounting
clips on the rear trim panels.
Do not place any objects on the cargo area cover. They may
obstruct your vision or strike occupants of the vehicle in the
case of a sudden stop or collision.
The cover may cause injury in a sudden stop or accident if it is
not securely installed.

SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
SecuriLockypassive anti-theft system is an engine immobilization
system. This system prevents the engine from being started unless a
coded keyis used.
The SecuriLockypassive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.

The SecuriLockypassive anti-theft
system is not compatible with non-
Ford (aftermarket) remote start
systems. Use of these systems may
result in vehicle starting problems and
a loss of security protection. Large
metallic objects, electronic devices on
the key chain that can be used to
purchase gasoline or similar items, or
a second key on the same key ring as
the PATS ignition key may cause
vehicle starting issues. If present, you
need to keep these objects from
touching the PATS ignition key while
starting the engine. These objects and
devices cannot damage the PATS ignition key, but can cause a momentary
issue if they are too close to the key during engine start. If a problem
occurs, turn ignition OFF and restart the engine with all other objects on the
key ring held away from the ignition key. Check to make sure the encoded
ignition key is an approved Ford encoded ignition key.
If your keys are lost or stolen you
will need to do the following:
²Use your spare key to start the
vehicle. or
²Have your vehicle towed to a
dealership or locksmith. The key
codes will need to be erased from
your vehicle and new key codes will need to be re-coded.
Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correct PATS key must be used for your vehicle. The use of the
wrong type of PATS key may lead to a ªNO-STARTº condition. Refer to
the Rotunda Key Application Matrix for the correct PATS key type for
your particular vehicle make and model year. If a key Application Matrix
is not available, call 1±800±ROTUNDA (1±800±768±8632) (press 2) to
order a Key Application Matrix.
If an unprogrammed key is used in the ignition it will cause a
ªNO STARTºcondition.

Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLockykeys can be used. To program acoded keyyourself, you
will need two previously programmedcoded keys(keys that already
operate your vehicle's engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available (one or both
of your original keys were lost or stolen), you must bring your vehicle to
your dealership to have the spare coded key(s) programmed.
Please read and understand the entire procedure before you begin.
1. Insert the first previously
programmedcoded keyinto the
ignition and turn the ignition from 2
(ACC) to 3 (ON) (maintain ignition
in 3 (ON) for at least one second).
2. Turn ignition to 1 (LOCK) and
remove the firstcoded keyfrom
the ignition.
3. Within ten seconds of turning the
ignition to 2 (ACC), insert the
second previously programmedcoded keyinto the ignition and turn the
ignition from 2 (ACC) to 3 (ON) (maintain ignition in 3 (ON) for at least
one second but no more than ten seconds).
4. Turn the ignition to 1 (LOCK) and remove the secondcoded key
from the ignition.
5. Within 20 seconds of turning the ignition to 2 (ACC), insert the new
unprogrammed key (new key/valet key) into the ignition and turn the
ignition from 2 (ACC) to 3 (ON) (maintain ignition in 3 (ON) for at least
one second). This step will program your new key to a coded key.
6. To program additional new unprogrammed key(s), repeat this
procedure from step 1.
If successful, the new coded key(s) will start the vehicle's engine and the
theft indicator will illuminate for three seconds and then go out.
If not successful, the new coded key(s) will not start the vehicle's engine
and the theft indicator will flash on and off. If failure repeats, bring your
vehicle to your dealership to have the new spare key(s) programmed.
