1999 FORD CROWN VICTORIA service

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 good quality fuel 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.
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.
Air bag readiness
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to flash
or remains on, have the system
serviced immediately.
Safety belt
Momentarily illuminates when the
ignition is turned to the ON position
to remind you to fasten your safety
belts. For more information, refer to
theSeating and safety restraints
chapter.
Brake system warning (if equipped)
Momentarily illuminates when the
ignition is turned to the ON
position, the engine is off and the
parking brake is engaged. If brake
warning lamp does not illuminate at
this time, seek service immediately. Illumination after releasing the
parking brake indicates low brake fluid level and the brake system should
be inspected immediately.
Anti-lock brake system (ABS) (If equipped)
Momentarily illuminates when the
ignition is turned on and the engine
is off. If the light does not illuminate
momentarily at start up, remains on
or continues to flash, the ABS needs
to be serviced. With the ABS light on, the anti-lock brake system is
disabled and normal braking is still effective unless the brake warning
light also remains illuminated with parking brake released.

vehicle serviced.
This light also illuminates briefly when the ignition key is turned to ON.
Air suspension (if equipped)
This light tells you if the air
suspension needs repair or if the air

system begins applying and
releasing the brakes and adjusting
the engine characteristics to limit a
wheelspin condition. It will be lit for
a minimum of four seconds or for
the duration of the Traction
Controlyevent.

Engine coolant temperature gauge
Indicates the temperature of the engine coolant. At normal operating
temperature, the needle remains within the normal area (the area
between the ªHº and ªCº). If it enters the red section, the engine is
overheating. Stop the vehicle as soon as safely possible, switch off the
ignition and let it cool. Refer toEngine coolantin theMaintenance
and carechapter.
Never remove the coolant recovery cap while the engine is
running or hot.
²Standard instrument cluster
²Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine
coolant andCheck Engine/Service Engine Soonindicators illuminate,
refer toWhat you should know about fail-safe coolingin the
Maintenance and care chapter.

If ªCOº or ªCSº is displayed, there is a problem with the fuel indication
system and you should contact your dealer for service as soon as
possible.
AVG ECON (average fuel economy)
Select this function to display your
average fuel economy in liters/100
km or miles/gallon.
If you calculate your average fuel
economy by dividing miles traveled by gallons used, your figure may be
different than displayed for the following reasons:
²your vehicle was not perfectly level during fill-up
²differences in the automatic shut-off points on the fuel pumps at
service stations
²variations in top-off procedure from one fill-up to another
²rounding of the displayed values to the nearest 0.1 liter (gallons)
Press the RESET control while AVG
ECON is displayed to reset the
function.
The average displayed is the average
since the last reset.
TRIP A and TRIP B
These two functions allow you to
see how far you have traveled since
you last reset. Trip A and Trip B are
completely independent and must
be reset individually.
