REMOTE KEYLESS ENTRY AND ANTI-THEFT SYSTEM 9T–3
DAEWOO M-150 BL2
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:

The door is opened.

The ignition switch is turned ON.

The tailgate is opened.

The hood is opened.
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.

9T–14 IMMOBILIZER ANTI-THEFT SYSTEM
DAEWOO M–150 BL2
D19T002B
DIAGNOSTIC TROUBLE CODE (DTC) 1600
ECM IMMOBILIZER ERROR (NO ANSWER)
Circuit Description
When the ignition is turned ON, the key is tested by the
immobilizer anti-theft system. While the key code is be-
ing 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 memory of the immobilizer con-
trol unit. If a valid key is detected, the immobilizer control
unit sends a serial data release message to the elec-
tronic control module (ECM). Included in the release
message is an identification (ID) code which assures
that neither the immobilizer control unit nor the ECM has
been substituted to defeat the system. If the ECM re-
ceives an invalid release message, the ECM performs
the following actions:
Disables the fuel injector circuit.

Disables the fuel pump circuit.

Disables the ignition coil.
DTC Will Set When

The ECM does not receive the signal from the immo-
bilizer control module when the ignition is turned on.

The above conditions are maintained until the ignition
is switched OFF.
DTC 1600 Will Clear When

The ignition switch is turned OFF or the scan tool
TROUBLE CODE CLEAR command is issued.

DIAGNOSTIC TROUBLE CODE (P) 1628 (SIRIUS D3)
ECM IMMOBILIZER ERROR (NO SUCCESSFUL COMMUNICATION)
Circuit Description

P 1628 Will Set When

The ECM does not receive the signal from the immo-
bilizer control module within 1.260 seconds after the
ignition is turned on.

The above conditions are maintained until the ignition
is switched OFF.
P 1628 Will Clear When

The ignition switch is turned OFF or the scan tool
TROUBLE CODE CLEAR command is issued.
