9T – 2 REMOTE KEYLESS ENTRY AND ANTI-THEFT SYSTEM

DESCRIPTION AND OPERATION

REMOTE KEYLESS ENTRY AND

ANTI-THEFT SYSTEM

The remote keyless entry and anti-theft system can per-

form the following functions:

SECURITY INDICATOR

There is a security indicator on the instrument panel. Af-

ter 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 1/8

second and OFF for 7/8 second. It then flashes at that

frequency until the control module/receiver is disarmed.

Sense intrusion into the vehicle through the doors,

the tailgate, or the hood.

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 tailgate is opened, the

hood open switch, the door open switch, or the tailgate

open switch will change its input to ground. The alarm

will be activated if the hood open sensor, the door open

sensor, or the tailgate open sensor changes its input to

ground before either of the following conditions occurs:

Activate a warning to signal an intrusion.

Help the driver find the vehicle in a parking area.

Automatically re-lock the doors if a door or the trunk is

not opened within 30 seconds after the vehicle has

been unlocked by the remote keyless entry.

Communicate serial data to a scan tool to help diag-

nose system faults.

The remote keyless entry and anti-theft system consists

of the following components:

An UNLOCK message is received from the transmit-

ter.

Security indicator.

Tailgate open switch.

SIREN

The remote keyless entry system is armed when the

LOCK message is received from the transmitter when

the ignition is OFF. When the system is armed, it will ac-

tivate the siren and flash the turn signals for 28 seconds

if any of the following conditions occurs:

Door open switches.

Central locking unit.

Flashing turn signal lamps.

Siren.

Hood open switch.

A door is opened (front door open switch input is

changed to ground).

REMOTE LOCKING AND UNLOCKING

The hand-held transmitter locks and unlocks the vehicle

doors by sending radio waves to the control module/re-

ceiver in the vehicle. The effective range of the transmit-

ter 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:

The tailgate is opened (tailgate open switch input is

changed to ground).

The hood is opened while the anti-theft system is

armed (hood open switch input is changed to

ground).

The siren is disarmed when any of the following condi-

tions occurs:

The doors are unlocked.

The UNLOCK button or the LOCK button on the re-

mote transmitter is pressed.

The turn signal lamps flash twice.

VEHICLE LOCATOR

The remote keyless entry system assists the driver in lo-

cating the vehicle. When the vehicle is unlocked with the

remote control, the turn signals flash twice to indicate

the location of the vehicle. The duration of the flashes

and the length of time between flashes is used to indi-

cate certain vehicle conditions. Refer to “Fault or Alarm

Indication” in this section.

The control module is disarmed.

Pressing the LOCK button has the following effects:

The turn signal lamps flash once.

The control module is armed.

The transmitter has a replaceable battery. The battery is

designed to last at least two years before replacement is

necessary.

DAEWOO M-150 BL2

Remotely lock and unlock the vehicle doors with a

hand-held high-frequency transmitter.

Keyless entry and anti-theft control module/receiver.

The ignition switch is turned ON with the key.

The doors are locked.

REMOTE KEYLESS ENTRY AND ANTI-THEFT SYSTEM 9T – 3

AUTOLOCKING (SAFETY LOCK)

The remote keyless entry system features an autolock-

ing 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 seconds unless any of the following events occur:

CONTROL MODULE/RECEIVER

The remote keyless entry control module/receiver is

contained in the tie-bar center. The module/receiver pro-

cesses signals from the remote transmitter and the in-

trusion sensors, and it activates the alarm if an intrusion

is detected.

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.

The ignition switch is turned ON.

The tailgate is opened.

The hood is opened.

PASSWORD PROGRAMMING

If a transmitter is lost or damaged, the control module/

receiver must be re-programmed to communicate with a

new transmitter. The passwords recorded in the control

module/receiver should not be deleted when power is off

in the control module/receiver.

Each control module/receiver should be able to record

five passwords. The following method is used to record

new passwords in the control module/receiver:

1. Connect the scan tool to the data link connector

(DLC) connector.

2. Send the programming mode message to the control

module/receiver.

3. Press any button of the transmitter to generate a data

code including a password which will be recorded by

the control module/receiver. The control module/re-

ceiver sends a response message to the scan tool to

indicate that the first password has been recorded.

4. Press any button of the transmitter three more times

until the control module/receiver has responded that

the third, fourth, and fifth passwords have been re-

corded.

5. Disconnect the scan tool.

The control module/receiver leaves the programming

mode automatically and switches to the normal operat-

ing mode when either of the following conditions occurs:

Five passwords are recorded in the control module/

receiver.

The scan tool is disconnected from the DLC.
