2000 FORD EXCURSION ECU

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.
Service engine soon
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). The OBD II system protects the

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.

SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
The SecuriLockypassive anti-theft system provides an advanced level of
vehicle theft protection. Your vehicle's engine can only be started with
the two special SecuriLockyelectronically coded keys provided with
your vehicle. Each time you start your vehicle, the SecuriLockykey is
read by the SecuriLockypassive anti-theft system. If the SecuriLocky
key identification code matches the code stored in the SecuriLocky
anti-theft system, the vehicle's engine is allowed to start. If the
SecuriLockykey identification code does not match the code stored in
the system or if a SecuriLockykey is not detected (vehicle theft
situation), the vehicle's engine will not operate.
If there is any potential SecuriLockyanti-theft problem with your
vehicle, ensureALL SecuriLockykeysfor that vehicle are brought to
the dealership, to aid in troubleshooting.
The SecuriLockypassive anti-theft system is not compatible with
aftermarket remote start systems. Use of these systems may result in

vehicle starting problems and a loss of security protection. Large metallic
objects, a second key or electronic devices used to purchase gasoline or
similar items on the same key ring as the PATS ignition key may cause
vehicle starting problems. If present, you need to keep these objects
from touching the PATS ignition key while starting the engine. These
objects cannot damage the PATS ignition key, but can cause a
momentary problem if they are too close to the key during engine start.
If a problem occurs, turn the 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.
Spare SecuriLockykeys can be purchased from your dealership and
programmed to your SecuriLockypassive anti-theft system. Refer to
Programming spare SecuriLockykeysfor more information.
If one or both of your SecuriLockykeys are lost or stolen and you want
to ensure the lost or stolen key will not operate your vehicle, bring your
vehicle and all available SecuriLockykeys to your dealership for
reinitialization.
Theft indicator
The theft indicator on the instrument cluster will operate as follows:
²When the ignition is OFF, the theft indicator will flash briefly every
two seconds to indicate the SecuriLockysystem is protecting your
vehicle.
²When the ignition is turned to ON or START, the theft indicator will
light for three seconds and then go out. If the theft indicator stays on
for an extended period of time or flashes rapidly, have the system
serviced by your dealership or a qualified technician.
Programming spare SecuriLockYkeys
Spare SecuriLockykeys can be purchased from your dealership and
programmed to your SecuriLockypassive anti-theft system (up to a
total of eight keys). Your dealership can program your new SecuriLocky
key(s) to your vehicle or you can do it yourself using the following
simple procedure. To program a new SecuriLockykey yourself, you will
need two previously programmed SecuriLockykeys (keys that already
operate your vehicle's engine). If two previously programmed
SecuriLockykeys 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 SecuriLockykey(s) programmed.
