2004 CHEVROLET CAVALIER ECU

{CAUTION:
Both frontal and side impact air bags inate
with great force, faster than the blink of an
eye. If you are too close to an inating air bag,
as you would be if you were leaning forward, it
could seriously injure you. Safety belts help
keep you in position for air bag ination before
and during a crash. Always wear your safety
belt, even with frontal air bags. The driver
should sit as far back as possible while still
maintaining control of the vehicle. Front
occupants should not lean on or sleep against
the door.
{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
see the part of this manual called “Older
Children” or “Infants and Young Children.”

Section 2 Features and Controls
2-1

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization” under
“Remote Keyless Entry System Operation” following
this section.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors or unlock your trunk from about 3 feet
(1 m) up to 30 feet (9 m) away using the remote keyless
entry transmitter supplied with your vehicle.
In addition, the system illuminates the interior lamps for
a set period of time. Also, a content theft security
system can be activated to monitor and set a horn alarm
if the vehicle’s door or trunk is opened without rst
unlocking the door or trunk with the remote keyless entry
transmitter.
The remote keyless entry system consists of a receiver,
which is located in the vehicle, and two hand held
transmitters.
2-4

The following functions are
available with the remote
keyless entry system:
LOCK:Press this button to automatically lock all doors.
In addition, if all doors and the trunk are closed, the
headlamps will ash once, the interior lamps will turn off,
and the vehicle content theft security system will arm.
SeeContent Theft-Deterrent on page 2-14.
UNLOCK:Press this button to unlock the driver’s door.
In addition, the headlamps will ash twice, the interior
lamps will turn on for about 20 seconds or until the
ignition is turned on, and the content theft security
system will disarm. SeeContent Theft-Deterrent on
page 2-14. If you press this button again within
ve seconds, all remaining doors will unlock.V(Trunk Release):Press this button to open the
trunk. You can open the trunk with the transmitter when
the vehicle speed is less than 2 mph (3 km/h). The
headlamps will ash twice.
L(Panic):Press this button to sound the horn and
make the headlamps and interior lamps ash alternately.
They can be turned off by pressing this button again
or by turning the ignition to ON. The alarm will sound for
two minutes unless cancelled by the driver.
Your dealer can change the settings to disable the
headlamp ash and horn chirp features. Your dealer can
also change the settings to allow the horn to chirp
twice on the rst press of the UNLOCK button. See your
dealer for more information.
Radio Personalization
Your vehicle can store different radio preset stations
depending on which keyless entry transmitter you use to
unlock the doors. The radio will recall all the stored
settings associated with that transmitter. Any radio
setting changes will be assigned to the transmitter last
used to unlock the doors.
This feature can be disabled by your dealer if you
desire. Contact your dealer for further information.
2-5

Resynchronization
Your remote keyless entry system is equipped with a
security system that prevents anyone from recording and
playing back your signal. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal that has been sent to it
more than once.
Normally, the transmitter and receiver resynchronize
automatically. However, under certain circumstances,
manual resynchronization may be required.
To resynchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons on
the transmitter at the same time.
3. Hold the buttons for at least 10 seconds. During this
time, the doors should lock and unlock once. This
conrms the resynchronization. If the doors do
not lock and unlock, see your dealer for service.
Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.
2-7

Rear Door Security Locks
If your vehicle is a
four-door model, it is
equipped with rear door
security locks that
help prevent passengers
from opening the rear
doors on your vehicle from
the inside.
Using the Rear Door Security Lock
1. Use a key to move the lock all the way up.
2. Close the door.
3. Do the same thing to the other rear door lock.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.
Opening a Rear Door When the
Security Lock is On
1. Unlock the door from the inside.
2. Then open the door from the outside.
If you do not cancel the security lock feature, adults or
older children who ride in the rear will not be able to
open the rear door from the inside. You should let adults
and older children know how to cancel the locks.
Canceling the Rear Door Security Lock
1. Unlock the door from the inside and open the
door from the outside.
2. Use a key to move the lock all the way down.
3. Do the same for the other rear door.
The rear door lock will now work normally.
2-9

Remote Trunk Release
Press the remote trunk release button, located on the
lower left side of the instrument panel, to release
the trunk lid.
If your vehicle is equipped with the remote keyless entry
system, the daytime running lamps will ash twice.
The remote trunk release will only work when either
the ignition is in OFF or ACCESSORY, the parking
brake is engaged, or the vehicle speed is less
than 2 mph (3 km/h).
Emergency Trunk Release Handle
Notice:Using the emergency trunk release handle
as a tie-down or anchor point when securing
items in the trunk may damage it. Use the
emergency trunk release handle only to help you
open the
trunk lid.
There is a glow-in-the-dark emergency trunk release
handle located on the inside of the trunk lid of your
vehicle. This handle will glow following exposure to light.
Pull the release handle up to open the trunk from the
inside.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Arming the System
With the ignition off, press the LOCK button on the
remote keyless entry transmitter to arm the system
immediately after all doors and the trunk are closed. If
the LOCK button is pressed again within ve seconds,
the horn will chirp to conrm that the system has
been armed.
Once the system is armed, the THEFT SYSTEM light
on your instrument panel will ash and remain ashing.
This conrms the system is armed and monitoring
the doors and trunk. If the light is on solid, the system is
not properly activated due to either a door or the
trunk being ajar.
If you don’t want to arm the system, lock the car with
the lock levers on the doors or with the power door
lock switch.
Disarming the System
If the system is armed, press the UNLOCK button on
the transmitter to disarm the system. The THEFT
SYSTEM light will stop ashing.
If the system is armed, turning the key to START will
also disarm the system.
If the system is armed and the trunk is opened using
the trunk release button on the transmitter, the system
will temporarily disarm itself and re-arm when the
trunk has been closed. This allows the customer to exit
the vehicle, lock the doors using the transmitter, and
open the trunk using the transmitter without having
to disarm and subsequently re-arm the system.
How the System Alarm is Activated
If the system is armed, opening any door or trunk, or
using a wrong key to start the vehicle will cause a
pre-alarm chirp for 10 seconds and then a full alarm of
horn and headlights for two minutes.
If an alarm event has nished and all doors and trunk
are closed, the content theft security system will
re-arm itself.
