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.

ECM IMMOBILIZER ERROR (INCORRECT ANSWER)
Circuit Description

ing read by the immobilizer control unit, the engine can

the following actions:
Disables the fuel injector circuit.
Disables the fuel pump circuit.
Disables the ignition coil.
DTC 1601 Will Set When
The ECM receives an incorrect release message
from the immobilizer control unit more than five times.
DTC 1601 Will Clear When
The ignition switch is turned OFF or the scan tool
TROUBLE CODE CLEAR command is issued.
