2001 CHEVROLET CAVALIER ECU

2-7 Power Door Locks (If Equipped)
You can lock or unlock
all doors on your vehicle
from the driver's or
front passenger's door
lock switch.
Push the lower portion of the switch to lock the doors.
Push the upper portion of the switch to unlock the doors.
The switch on each rear door works only that door's
lock. It won't lock (or unlock) all of the doors
-- that's a
safety feature.
Rear Door Security Lock (4-Door Models)
Your vehicle is equipped
with rear door security
locks that help prevent
passengers from opening
the rear doors on your
vehicle from the inside.
To Use One of These Locks
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.

2-8
To Open a Rear Door With the Security Lock
1. Unlock the door from the inside.
2. Then open the door from the outside.
If you don't cancel the security lock feature, adults or
older children who ride in the rear won't be able to open
the rear door from the inside. You should let adults and
older children know how to cancel the locks.
To Cancel the Rear Door 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.
Lockout Prevention (If Equipped)
If your vehicle is equipped with remote keyless entry,
you have lockout protection. This feature stops the
power door locks from locking when the keys are in
the ignition and the door is open.
If the power door lock switch is pressed when a door
is open and the key is in the ignition, all the doors will
lock and the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, open your door and
set the locks from the inside. Then get out and close
the door.
Remote Keyless Entry (If Equipped)
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 first
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.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.

2-10 Operation
The following
functions are available
with the remote
keyless entry system:
LOCK: All doors will automatically lock when the
LOCK button is pressed. In addition, if all doors and
the trunk are closed, the headlamps will flash once, the
interior lamps will turn off, and the vehicle content theft
security system will arm. See ªContent Theft Security
Systemº later in the section.UNLOCK: The driver's door will unlock when the
UNLOCK button on the transmitter is pressed. In
addition, the headlamps will flash 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. See ªContent Theft Security
Systemº later in the section. If you press UNLOCK
again within five seconds, all remaining doors
will unlock.
Trunk Release: The trunk will unlock anytime
when the vehicle symbol on the transmitter is pressed
and the vehicle speed is less that 2 mph (3 km/h).
The headlamps will flash twice.
Horn Symbol: The horn will sound and the
headlamps and interior lamps will flash alternately when
this button is pressed. This can be turned off by pressing
the horn symbol 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 flash and horn chirp features. Your dealer can
also change the settings to allow the horn to chirp twice
on the first press of the UNLOCK button. See your
dealer for more information.

2-12 Replacing the Battery in the Remote
Keyless Entry System Transmitter
To replace the battery in the transmitter:
1. Use a coin or screwdriver to separate the bottom half
from the top half of the transmitter.
2. Remove the battery and replace it with the new one.
Make sure the positive (+) side of the battery faces
down. For battery replacement, use a three
-volt
battery, type CR2032, or equivalent.
3. Read the instructions inside the case.4. Put the two halves back together. Make sure the
cover is on tightly, so water won't get in.
5. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
resynchronizing the transmitter with the receiver.
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
confirms the resynchronization. If the doors do not
lock and unlock, see your dealer for service.

2-14 Trunk Release Handle (If Equipped)
NOTICE:
The trunk release handle was not designed to be
used to tie down the trunk lid or as an anchor
point when securing items in the trunk. Improper
use of the trunk release handle could damage it.
There is a glow-in-the-dark 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.
Trap-Resistant Trunk Kit
To help prevent a child from becoming trapped in your
trunk, you can order a trap
-resistant trunk kit from your
dealer. This kit includes:

a modified trunk latch,

a lighted release handle, and

seatback tethers (for vehicles with folding
rear seatbacks).
See your dealer for additional information.
Theft
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. However, there are ways you
can help.

2-16
Content Theft Security System
(If Equipped)
Arming the System
With the ignition off, pressing the transmitter LOCK
button will arm the system immediately after all doors
and trunk are closed. If the transmitter LOCK button
is pressed again within five seconds, the horn will chirp
to confirm that the system had been armed.
Once the system is armed, the THEFT SYSTEM light
on your instrument panel will flash and remain flashing.
This confirms the system is armed and monitoring the
doors and trunk.
If you don't want to arm the system, lock the car
with the lock levers on the doors or with the door
lock switch.
Disarming the System
If the system is armed, pressing the UNLOCK button
on the transmitter will disarm the system. The THEFT
SYSTEM light will stop flashing.
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 button on the transmitter, the system will
temporarily disarm itself and rearm 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 rearm 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 finished and all doors and trunk are
closed, the content theft security system will re
-arm itself.
How to Turn Off the System Alarm
If the system alarm is active, it can be deactivated by:

Pressing the transmitter LOCK or PANIC button
to turn
-off alarm. The system will also rearm if all
doors and trunk are later closed, or

pressing the transmitter UNLOCK or TRUNK
button to turn
-off alarm and disarm system, or

putting the key in the ignition and turning it to
START to turn
-off alarm and disarm the system.

2-17 How to Detect a Tamper Condition
If you hear three horn chirps when you press the
UNLOCK, TRUNK or LOCK buttons on your
transmitter, that means the Content Theft Security
system alarm was triggered while you were away.
Your dealer can change the settings to disable the
headlamp flash and horn chirp features. Your dealer can
also change the settings to allow the horn to chirp twice
on the first press of the UNLOCK button. See your
dealer for more information.
Passlock

Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.During normal operation, the THEFT SYSTEM light
will go off approximately five seconds after the key is
turned to the RUN ignition position following an
engine start.
If the engine stalls and the THEFT SYSTEM light
flashes, wait until the light stops flashing before trying
to restart the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the THEFT SYSTEM light
comes on, you will be able to restart the engine if you
turn the engine off. However, your Passlock system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock at this
time. You may also want to check the fuses (See ªFuses
and Circuit Breakersº in the Index). See your dealer for
service. Also, see ªRoadside Assistanceº in the Index
for more information.

2-50 Center Console Cupholders
There are two cupholders located at the front of the
center console, in front of the shift lever. There are also
cupholders for the rear seat passengers located under
the center console lid. Open the center console lid all
the way to uncover the rear cupholders. There is also
a large, removeable cupholder inside of the center
console lid.
Convenience Net (If Equipped)
Your vehicle may have a convenience net. You'll see it
inside the back wall of the trunk. Put small loads, like
grocery bags, behind the net. It can help keep them from
falling over during sharp turns or quick starts and stops.
Unclip a corner of the convenience net to fit larger
objects behind the net, then reclip it to secure them
in place.
The net isn't for larger, heavier loads. Store them in the
trunk as far forward as you can.
You can unhook the net so that it will lie flat when
you're not using it.
Ashtrays and Cigarette Lighter
(If Equipped)
To use the lighter, just push it in all the way and let go.
When it's ready, it will pop back out by itself.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
To clean the center console ashtray, remove the entire
ashtray and empty it.
NOTICE:
Don't put papers and other things that burn into
your ashtrays. If you do, cigarettes or other
smoking materials could set them on fire,
causing damage.
