2001 Mercury Grand Marquis ECU

Check engine
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). This OBD II system protects the environment by ensuring that your
vehicle continues to meet government emission standards. The OBD II
system also assists the service technician in properly servicing your
vehicle.
TheCheck Engineindicator 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 check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourCheck Enginelight 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, theCheck
Enginelight 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 theCheck Enginelight remains on, have your vehicle serviced at the
first available opportunity.

HOMELINKTUNIVERSAL TRANSCEIVER (IF EQUIPPED)
The HomeLinktUniversal Transceiver, located on the driver's visor,
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.
Do not use the HomeLinktUniversal Transceiver with any garage door
opener that lacks safety stop and reverse features as required by U.S.
federal safety standards (this includes any garage door opener model
manufactured before April 1, 1982). A garage door which cannot detect
an object, signaling the door to stop and reverse, does not meet current
U.S. federal safety standards. For more information on this matter, call
toll-free: 1±800±355±3515 or on the Internet atHomeLink.jci.com.
Programming
Do not program the HomeLinktUniversal Transceiver with the
vehicle parked in the garage.
1. Prepare for programming the
HomeLinktUniversal Transceiver by
erasing the three factory default
codes by holding down the two
outside buttons until the red light
begins to flash after 20 seconds.
Release both buttons.
2. Hold the end of your hand-held
transmitter 5±14 cm (2±5 inches)
away from the HomeLinktUniversal
Transceiver surface (located on your visor) while keeping the red light in
view.

To reprogram the transmitters
yourself, place the key in the
ignition and turn from 2 (LOCK) to
3 (OFF) and cycle between 3 (OFF)
and 4 (ON) four times in rapid
succession within 3 seconds. After
doors lock/unlock, press any control
on all transmitters (up to four).
When completed, turn the ignition
to 3 (OFF).
All transmittersmustbe programmed at the same time.
SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
SecuriLockypassive anti-theft system is an engine immobilization
system. This system prevents the engine from being started unless a
coded key programmed to your vehicleis 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.
Automatic arming
The vehicle is armed immediately
after switching the ignition to the 3
(OFF) position. The
THEFTlight in
the instrument cluster will flash
every two seconds when the vehicle
is armed.
Automatic disarming
Switching the ignition to the 4 (ON) position with acoded keydisarms
the vehicle. The
THEFTlight will illuminate for three seconds and then
go out. If theTHEFTlight stays on for an extended period of time or
flashes rapidly, have the system serviced by your dealership or a
qualified technician.

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 correctcoded keymust be used for your vehicle. The use of the
wrong type ofcoded keymay lead to a ªNO-STARTº condition.
If an unprogrammed key is used in the ignition it will cause a
ªNO STARTº condition.
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, 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.

When installing a child safety seat:
²Review and follow the information
presented in theAir Bag
Supplemental Restraint System
(SRS) section in this chapter.
²Use the correct safety belt buckle
for that seating position (the
buckle closest to the direction the
tongue is coming from).
²Insert the belt tongue into the
proper buckle until you hear a
snap and feel it latch. Make sure
the tongue is securely fastened in
the buckle.
²Keep the buckle release button
pointing up and away from the
safety seat, with the tongue
between the child seat and the
release button, to prevent accidental unbuckling.
²Place seat back in upright position.
²Put the safety belt in the automatic locking mode. Refer toAutomatic
locking mode(passenger side front and outboard rear seating
positions) (if equipped) section in this chapter.
Ford recommends the use of a child safety seat having a top tether
strap. Install the child safety seat in a seating position which is capable
of providing a tether anchorage. For more information on top tether
straps, refer toAttaching child safety seats with tether straps.in this
chapter.
Carefully follow all of the manufacturer's instructions included
with the safety seat you put in your vehicle. If you do not install
and use the safety seat properly, the child may be injured in a sudden
stop or collision.
