2004 CHEVROLET EPICA ECU

One key is used for the
ignition, the doors and
all other locks.
When a new vehicle is delivered, the dealer removes the
key tag and gives it to the first owner. The tag has a
code on it that tells your dealer how to make extra keys.For vehicle security, keep the key tag in a safe place and
also record the key number somewhere other than inside
of the vehicle. If you lose your key, you will be able to
have a new one made easily using the tag.
Your vehicle may have an electronic immobilizer
designed to protect your car against theft. If so, only
keys with the correct electronic code can be used
to start the vehicle. Even if a key has the same profile,
it will not start the engine if the electronic code is
incorrect. If you need a new key, contact your dealer
who can obtain the correct key code. SeeRoadside
Assistance Program on page 7-6for more information.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.

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.
Theft-Deterrent System
Your vehicle has a theft-deterrent system.
The theft-deterrent system will not arm when you lock the
doors using the key or the manual door lock. It activates
only when you use the remote keyless entry transmitter.
Arming the System
To arm the system, do the following:
1. Turn the key to LOCK and remove the key from
the ignition.
If the key is inserted in the ignition, the transmitter
will not operate the theft-deterrent system.
2. Close the doors, the windows, the hood, and
the trunk.
Ensure that the windows are closed, as the system
can be activated even if the windows are open.3. Lock the door using the remote keyless entry
transmitter. The transmitter must be used to activate
the theft-deterrent system.
•The LED on the transmitter will flash.
•All of the doors will lock.
•The hazard warning lamps will flash once and
the horn will chirp.
•The theft-deterrent mode will arm.
•The security light will flash once every second to
indicate that the theft-deterrent system is armed.
The security light is located on the top center
of the instrument panel, near the windshield.
To avoid activating the alarm by accident, do one of
the following:
•Unlock the driver’s or passenger’s front door using
the key.
•Press the lock/unlock button on the remote keyless
entry transmitter.
Unlocking a door any other way will activate the alarm
when a door or the trunk is opened.
If you do not want to arm the theft-deterrent system,
lock the vehicle using the key or the manual door locks.

Immobilizer
This device complies with Part 15 of the FCC Rules.
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.
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 modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Immobilizer Operation
Your vehicle may have a passive theft-deterrent system.
The immobilizer system prevents your vehicle from
being started by unauthorized persons.
If your vehicle has an immobilizer system, your vehicle
has a special key that works with the theft-deterrent
system. There is a transponder in the key head that is
electronically coded. The correct key will start the
vehicle. An invalid key immobilizes the engine. The
immobilizer system isolates the power supply to
the ignition system, the fuel pump and the fuel injectors.
The engine immobilizer is activated after the key is turned
to LOCK and removed from the ignition. The security light
located on the top center of the instrument panel, near
the windshield, will flash when the immobilizer is active. If
the light does not flash after removing the key, have the
system checked by your dealer.
The immobilizer system works when you turn the key to
START. If the immobilizer system does not recognize the
electronic code, the engine will not start and the security
indicator will continue blinking. If your key is ever
damaged, you may not be able to start your vehicle.
2-17

When trying to start the vehicle, if the engine does
not start and the security light continues flashing, the
key may have a damaged transponder. Turn the ignition
off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another key. At this time, you may
also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-79. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the first key may be faulty. See your
dealer who can service the theft-deterrent system to
have a new key made.
Up to four keys may be programmed for the vehicle.
If you lose or damage your keys, only a GM dealer
can service the theft-deterrent system to have new
keys made.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however,
is not working properly and must be serviced by
your dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Chevrolet Roadside
Assistance. SeeRoadside Assistance Program
on page 7-6.Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km).
Do not make full-throttle starts.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in.
SeeTowing a Trailer on page 4-35for
more information.

CD Messages
No Maga:An empty magazine is inserted in the CD
changer. Try the magazine again with a CD loaded
in one of the trays.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer. If your radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.
Theft-Deterrent Feature
The theft-deterrent system is designed to discourage
theft of your radio. When the radio and vehicle are
turned off, your radio has a blinking red light to indicate
that the theft-deterrent system is activated.
The theft-deterrent system also activates when the
audio system has been disconnected from the battery.
When this occurs, the AF code and security code
will have to be entered in order to operate your radio.
An identification card stamped with the AF code
and security code will be provided with the vehicle.
Keep it in a safe place, not in the vehicle.To enter the security code do the following:
1. Turn the ignition to ACC or ON.
2. Turn the radio on. AF or COdE will flash on the
display. If AF flashes on the display, go to Step
2. If COdE flashes on the display, go to Step 4.
3. Enter the AF code by using the preset pushbuttons.
COdE will flash on the display.
4. Enter the security code by using the preset
pushbuttons. When the complete security code is
entered, the code will flash three times.
If the security code is not entered correctly, Err will
appear on the display for a few seconds. When
COdE appears back on the display, repeat Step 4.
If the incorrect AF code is entered, an incorrect
frequency level may be chosen and the radio
reception may be affected. If this occurs, reset the
audio system by removing and re-installing the
AUDIO fuse. See “Instrument Panel Fuse Block”
underFuses and Circuit Breakers on page 5-79for
more information. Then repeat Steps 1 through 4.
