ECU FORD F150 1999 10.G Owners Manual

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
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.
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 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, 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.

SECURILOCKYPASSIVE ANTI-THEFT SYSTEM
Your vehicle is equipped with a coded-key anti-theft system. Only the
correct key will be able to start your vehicle. If your keys are lost or
stolen, you must take your vehicle to your dealership for key
reprogramming.
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
Controls and features
76

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 top of the instrument panel 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 ON 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.
Programming spare SecuriLockYkeys
Spare SecuriLockykeys can be purchased from your dealership and
programmed to your SecuriLockyanti-theft system (up to a total of 8
Controls and features
77

keys). Your dealership can program your new SecuriLockykey(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 timely
implementation of each step in 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/valet 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 panel) will light for three seconds and then go out.
Controls and features
78

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.
REMOTE ENTRY SYSTEM
Your vehicle is equipped with a remote entry system which allows you to:
²unlock the vehicle doors without a key.

driver's door. The interior lamps will
illuminate.
Press the control a second time
within five seconds to unlock all
doors.
Locking the doors

or the driver's door.
To confirm doors are closed and
locked, press this control a second
time within five seconds. The
door(s) will lock again, the horn will
chirp once and the lamps will flash.

Combination lap and shoulder belts
1. Insert the belt tongue into the
proper buckle (the buckle closest to
the direction the tongue is coming
from) until you hear a snap and feel
it latch. Make sure the tongue is
securely fastened in the buckle.
2. To unfasten, push the release
button and remove the tongue from
the buckle.
The front and rear outboard safety restraints in the vehicle are
combination lap and shoulder belts. The front and rear seat passenger
outboard safety belts have two types of locking modes described below:
Vehicle sensitive mode
The vehicle sensitive mode is the normal retractor mode, allowing free
shoulder belt length adjustment to your movements and locking in
response to vehicle movement. For example, if the driver brakes
suddenly or turns a corner sharply, or the vehicle receives an impact of 8
km/h (5 mph) or more, the combination safety belts will lock to help
reduce forward movement of the driver and passengers.
The front seat belt system can also be made to lock manually by quickly
pulling on the shoulder belt. Rear seat belts (if equipped) cannot be
made to lock up by pulling quickly on the belt.
