9T–2 REMOTE KEYLESS ENTRY AND ANTI-THEFT SYSTEM
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
REMOTE KEYLESS ENTRY AND
ANTI-THEFT SYSTEM
The remote keyless entry and anti-theft system can per-
form the following functions:
Remotely lock and unlock the vehicle doors with a
hand-held high-frequency transmitter.
Sense intrusion into the vehicle through the doors,
the tailgate, or the hood.
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:
Keyless entry and anti-theft control module/receiver.
Security indicator.
Tailgate open switch.
Door open switches.
Central locking unit.
Flashing turn signal lamps.
Siren.
Hood open switch.
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 doors are unlocked.
The turn signal lamps flash twice.
The control module is disarmed.
Pressing the LOCK button has the following effects:
The doors are locked.
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.
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.
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:
An UNLOCK message is received from the transmit-
ter.
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:
A door is opened (front door open switch input is
changed to ground).
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 ignition switch is turned ON with the key.
The UNLOCK button or the LOCK button on the re-
mote transmitter is pressed.
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.
