1999 FORD RANGER ECU

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.

Anti-lock brake system (ABS)
Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If the light
remains on, continues to flash or
fails to illuminate, have the system
serviced immediately. 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.
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or
flash faster, check for a burned-out
turn signal bulb. Refer toExterior bulbsin theMaintenance and care
chapter.
High beams
Illuminates when the high beam
headlamps are turned on.
Anti-theft system (if equipped)
Refer toSecuriLockypassive
anti-theft systemin theControls

SECURILOCKYPASSIVE ANTI-THEFT SYSTEM (IF EQUIPPED)
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
passive 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.
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 or devices such as the Mobil Speedpassyon the same key ring
as your SecuriLockykey may cause vehicle starting problems. These
objects and devices cannot damage the SecuriLockykey, but can cause
a momentary problem if they are too close to the key when starting the
engine. If a problem occurs. turn ignition off and restart the engine with
all other objects on the key ring held away from the SecuriLocky
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 2
seconds to indicate the SecuriLockysystem is protecting your
vehicle.
²When the ignition is turned to RUN or START, the theft indicator will
light for 3 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.
The Theft indicator is controlled by theSecuriLockysystem.During
the 30 second prearm state, it is normal to see the theft indicator pulse
brighter behind the constant glow.
Programming spare SecuriLockYkeys
Spare SecuriLockykeys can be purchased from your dealership and
programmed to your SecuriLockypassive anti-theft system (up to a
total of 8 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.

Procedure to program spare SecuriLockYkeys to your vehicle
New SecuriLockykeys must have the correct mechanical key cut for
your vehicle.
Conventional (non-SecuriLocky) keyscannotbe programmed to your
vehicle.
You will need to have two previously programmed SecuriLockykeys and
the new unprogrammed SecuriLockykey readily accessible for the
procedure. Please read and understand the entire procedure before you
begin.
1. Insert the first previously programmed SecuriLockykey into the
ignition and turn the ignition from OFF to RUN (maintain ignition in
RUN for at least one second).
2. Turn ignition to OFF and remove the first SecuriLockykey from the
ignition.
3. Within five seconds of turning the ignition to OFF, insert the second
previously programmed SecuriLockykey into the ignition and turn the
ignition from OFF to RUN (maintain ignition in RUN for at least one
second but no more than 5 seconds).
4. Turn the ignition to OFF and remove the second SecuriLockykey
from the ignition.
5. Within 10 seconds of turning the ignition to OFF, insert the
unprogrammed SecuriLockykey (new key) into the ignition and turn
the ignition from OFF to RUN (maintain ignition in RUN for at least one
second). This step will program your new SecuriLockykey.
6. To program additional SecuriLockykey(s), repeat this procedure from
step 1.
If the programming procedure was successful, the new SecuriLocky
key(s) will start the vehicle's engine. The theft indicator (located on the
instrument cluster) will light for three seconds and then go out.
If the programming procedure was not successful, the new SecuriLocky
key(s) will not operate the vehicle's engine. The theft indicator will flash
on and off. Wait at least one minute and then repeat the procedure from
step 1. If failure repeats, bring your vehicle to your dealership to have
the spare SecuriLockykey(s) programmed.
