GENERAL DESCRIPTION
AND SYSTEM OPERATION
the radio–frequency signal. A release message is sent to
the powertrain control module (PCM)/engine control module (ECM) if the key is authorized.
New keys are coded by using a scan tool. Refer to in this
section.”Key Coding Procedure”
IMMOBILIZER SYSTEM
The purpose of the immobilizer system is to prevent the
vehicle from being stolen or driven by unauthorized users.
Users are authorized by an electronically coded key.
When the ignition is turned ON, the key is tested by the immobilizer system. While the key code is being read by the
immobilizer control unit, the engine can start and run with
any key that will turn the lock cylinder. The key code is read
and compared with key codes that have been stored in the
immobilizer control unit’s memory.
If a valid key is detected, the immobilizer control unit sends
a serial data release message to the powertrain control
module (PCM)/engine control module (ECM). Included in
the release message is an identification (ID) code which
assures that neither the immobilizer control unit nor the
PCM/ECM has been substituted to defeat the system.
If the PCM/ECM does not receive a release message within a specified time, or if the ID codes do not match, the
PCM/ECM performs the following actions:
S Disables the fuel injector circuit.
S Disables the fuel pump circuit.
S Disables the ignition coil.
S Sets diagnostic trouble code (DTC) 53.
The above conditions are maintained until the ignition is
turned OFF.
The immobilizer control unit system consists of the following components:
S Electronically coded keys.
S Detection coil.
S Immobilizer control unit.
S PCM/ECM.
S Instrument cluster indicator.
S A data link connector (DLC) to provide serial data
access for a scan tool.
DETECTION COIL
A detection coil is mounted at the ignition lock as an integral part of the key position trim ring. The wires to and from
the detection coil are connected to the immobilizer. When
the ignition is turned ON, the immobilizer energizes the
detection coil and the coil is coupled inductively to the
transponder in the ignition key. The immobilizer sends a
modulated signal to the detection coil. The signal is
changed by interaction with the internal transponder in the
ignition key. The immobilizer reads the signal from the
detection coil and determines whether the key is authorized.
IMMOBILIZER CONTROL UNIT
The immobilizer control unit is an electronic module in the
instrument panel which verifies the validity of an ignition
key when the ignition is turned ON.
To accomplish its purpose, the immobilizer control unit
performs the following actions:
S Learns and stores the codes of valid keys.
S Reads the radio frequency input from the ignition
key.
SCompares the received code with the codes of the
valid keys.
SSends a release message to the powertrain control
module (PCM)/engine control module (ECM) if a
valid key has been presented.
SCalculates and transmits identification (ID) codes
within each release message.
SControls the external relay which interrupts the
starter relay circuit.
SControls the status indicator in the instrument clus-
ter.
S Monitors system faults.
S Supports system test functions.
A PCM/ECM for a vehicle without an immobilizer control
unit cannot be interchanged with a PCM/ECM that is used
with an immobilizer control unit system. The immobilizer
control unit and the PCM/ECM must have a matching ID
code. ID coding and key coding are accomplished by using
a scan tool.
ELECTRONICALLY CODED KEYS
Each valid ignition key has an internal transponder which
transmits a unique code. When a key is inserted into the
ignition lock, the transponder is inductively coupled to the
detection coil. The transponder interacts with the detection coil to generate an amplitude modulated modulated
signal which is conducted from the detection coil to the immobilizer control unit. The immobilizer control unit reads
Normal Operation
When the ignition is turned ON, the immobilizer control
unit tries to read the key code transmitted by the transponder in the ignition key.
If a valid key is detected, the immobilizer control unit sends
a release message to the PCM/ECM. The release message contains an ID code. Immobilization will be performed by the PCM/ECM if no release message is received, or if the ID code in the PCM/ECM does not match
the immobilizer control unit ID code.
If a non–valid key is detected, the release message is not
sent to the PCM/ECM.
When the driver turns the ignition OFF, the immobilizer
control unit switches to the active mode.
DAEWOO V–121 BL4
IMMOBILIZER ANTI–THEFT SYSTEM 9T – 11
Data Link Connector (DLC)
When the ignition is ON, a scan tool can switch the immobilizer control unit to the data link connector (DLC) mode
for the purpose of diagnostics, key coding, or ID coding.
ID Code Handling
One of 65,535 possible ID codes is stored in the immobilizer control unit’s memory.
The ID code can be erased by using the scan tools’RESET
ID CODE command. When the immobilizer control unit
calculates a new ID code, the PCM/ECM ID code must be
reset to match the immobilizer control unit ID code. To reset the ID code, refer to ”ID Code Reprogramming.”
During diagnostic procedures, the ID code can be read for
comparison with the PCM/ECM ID code by using the scan
tool’s READ IMMOBILIZER CONTROL UNIT IDCODE
command.
SERIAL DATA LINK
Serial data can be exchanged between a scan tool, the
powertrain control module (PCM)/engine control module
ECM), and the immobilizer control unit.
The scan tool connection is the data link connector (DLC).
POWERTRAIN CONTROL MODULE
(PCM)/ENGINE CONTROL MODULE
(ECM)
When the powertrain control module (PCM)/engine con-
trol module (ECM) detects that the ignition is being turned
ON, the PCM/ECM waits for a release message from the
immobilizer control unit. If a release message is not received within a specified time, the PCM/ECM disables the
engine. The engine is also disabled if the identification (ID)
code transmitted by the immobilizer control unit does not
match the code stored in the PCM/ECM’s memory. Immobilization remains in effect until the ignition is turned OFF,
or until battery power is removed.
To prevent the vehicle from being driven, the PCM/ECM
applies the following strategy:
S The ignition module is put in a bypass mode.
S The PCM/ECM will not create an electronic spark
timing (EST) output. Therefore, no spark will be
generated by the ignition coil.
S The PCM/ECM will not enable the fuel pump.
S The PCM/ECM will not enable the fuel injectors.
S The PCM/ECM sets diagnostic trouble code (DTC)
53.
Serial data communication is transmitted on a single wire
between the immobilizer control unit and the PCM/ ECM.
During diagnostic procedures or ID code changing, a scan
tool is added to the communication system.
A PCM/ECM with an immobilizer control unit is not exchangeable with a PCM/ECM that does not have an immobilizer control unit.

REMOTE LOCKING AND UNLOCKING
The transmitter has a replaceable battery. The battery is
designed to last at least three years before replacement
is necessary.
SECURITY INDICATOR
There is a security indicator on the instrument panel. After
the LOCK button of the transmitter is pressed, the module
is placed in the armed mode, and the security indicator
flashes. The security indicator turns ON for 0.1 second
and OFF for 0.7 second. It then flashes at that frequency
until the control module/receiver is disarmed. If the vehicle
is equipped with an immobilizer, the security indicator is
connected to the immobilizer system instead of the keyless entry/anti–– theft system.
INTRUSION SENSING
The anti–theft function is armed if the transmitter sends
the LOCK message to the control module/receiver when
the ignition is OFF.
When the hood, the door, or the rear deck lid is opened,
the hood open switch, the door open switch, or the trunk
open switch will change its input to ground. The alarm will
be activated if the hood open sensor, the door open sensor, or the trunk open sensor changes its input to ground
before either of the following conditions occurs:
SAn UNLOCK message is received from the trans-
mitter.
SThe front door tamper switch or the rear deck lid
tamper switch indicates key operation by changing
its input to ground.
The alarm also will be activated if the ignition input is
changed to battery voltage before either of the following
conditions occurs:
SAn UNLOCK message is received from the trans-
mitter.
SThe front door tamper switch or the rear deck lid
tamper switch indicates key operation by changing
its input to ground.
The hand–held transmitter locks and unlocks the vehicle
doors by sending radio waves to the control module/receiver in the vehicle. The effective range of the transmitter
varies between 5 and 10 meters (approximately 16 to 32
feet), depending on whether or not objects such as other
vehicles are blocking the path of the radio waves.
The transmitter has a LOCK button and an UNLOCK button which only function when the ignition is OFF. Pressing
the UNLOCK button has the following effects:
S The doors are unlocked.
S The turn signal lamps flash twice.

The remote keyless entry system features an autolocking
control. If the doors are unlocked with the remote transmitter when the control module/receiver is in the armed
mode, the doors are automatically re–locked after 30 sec-
onds unless any of the following events occur:
S The door is opened.
S The ignition switch is turned ON.
S The rear deck lid is opened.
S The hood is opened.
CONTROL MODULE/RECEIVER
The remote keyless entry control module/receiver is contained in the floor console. The module/receiver processes signals from the remote transmitter and the intrusion sensors, and it activates the alarm if an intrusion is
detected. The control module/receiver also has a selfdiagnostic function which will display trouble codes. In order to
display trouble codes, a scan tool must be connected to
the assembly line diagnostic link (ALDL) connector.
The control module/receiver will not communicate with
transmitters from other vehicles because there are over
four billion possible electronic password combinations,
and passwords are not duplicated. The control module/ receiver has an attached antenna to detect signals from the
transmitter.

Remote Keyless Entry Transmitter Programming Information
The Daewoo Remote Keyless Entry System allows for the use of as many as five (5)
transmitters for each vehicle. Replacement Remote Keyless Entry System Transmitters must
first be programmed to a specific vehicle using the Scan 100 Scan Tool. This process is
completed using serial data communication between the Scan 100 Scan Tool and the Remote
Keyless Entry Control Unit and is the only method available for programming Transmitters.
