8B–8 SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR)
DAEWOO M-150 BL2
DIAGNOSTIC INFORMATION AND PROCEDURES
D110B009A
BULB CHECK
As soon as the operating voltage is applied to the sens-
ing and diagnostic module (SDM) ignition input, the
SDM activates the warning lamp for a bulb check.
The SDM turns the lamp ON for 4 seconds, and then the
SDM turns the lamp OFF.
During the bulb check, the SDM is not ready to detect a
crash or deploy the supplemental inflatable restraints.
FAULT INDICATION
The sensing and diagnostic module records the sys-
tem’s faults in two categories:

Current faults and the fault code appears “Axx” on the
scan tool display.

Historic faults, which are those that were detected in
the past, but are no longer active. And the fault code
appears “Sxx” on the scan tool display.
The warning lamp:

Indicates a fault as soon as it occurs.

Stays ON, even if a fault is no longer active.A scan tool connected to the data link connector (DLC):

Reveals the fault codes.

Receives serial data transmission through the termi-
nal J (13) of the DLC.

Receives ground through the terminal A (4) of the
DLC.
CLEARING FAULT CODES
When the sensing and diagnostic module (SDM) re-
ceives the CODE ERASE command from the scan tool,
the SDM:

Clears the entire fault memory.

Turns OFF the warning lamp.

Resets for fault detection.
External Fault
Service personnel can reset the SDM and turn OFF the
warning lamp if the fault is an external fault.
Internal Fault
An internal fault of the SDM or a CRASH RECORDED
fault code cannot be reset.
In the case of an internal fault of the SDM or a CRASH
RECORDED fault code, the SDM must be replaced.
Voltage-Low Fault
The SDM will turn OFF the VOLTAGE LOW fault as
soon as the voltage recovers.
MICROPROCESSOR –
INDEPENDENT LAMP ACTIVATION
If the sensing and diagnostic module (SDM) electrical
connector is not properly attached, the SDM cannot
function and cannot control the warning lamp.
If this fault is present, the warning lamp will operate in-
dependently from the SDM through the use of shorting
bars that are built into the SDM connector.

The cigar lighter is located in the front portion of the in-
strument panel. To use the lighter, push it in completely.
When the lighter is hot, it will release itself from contact
with the heating element. The lighter and the heating
element can be damaged if the lighter is not allowed to
release itself fully from the heating element. Cigar lighter
is not equipped with the lamp.
ASHTRAY
The ashtray is located in the lower portion of the instru-
ment panel. In case of cleaning the ashtray up, remove
the ashtray by pushing the upper button and clean it up.
The ashtray lamp is optional.
INSTRUMENT PANEL VENTS
The center and the side vents in the instrument panel
can be adjusted up and down and from side to side. The
side vents can also be aimed toward the side windows in
order to defog them.
GLOVE BOX
The glove box can be opened by pulling up on the latch
handle. The glove box must be removed in order to gain
access to the passenger-side airbag module.
DIGITAL CLOCK
The digital clock is located in the instrument panel, be-
low the defroster grille. The clock is capable of a 12 –
hour display.
INSTRUMENT CLUSTER
The instrument cluster is located above the steering col-
umn and in the instrument cluster trim panel. The instru-
ment cluster contains the instruments that provide the
driver with vehicle performance information. The instru-
ment cluster contains a speedometer, an odometer, a
trip odometer, a temperature gauge, a fuel gauge, and
several indicator lamps. For replacement of the indicator
lamp bulbs contained in the instrument cluster, refer to
“Instrument Cluster Indicator Lamps Specifications” in
this section.
SPEEDOMETER/ODOMETER/TRIP
ODOMETER
The speedometer measures the speed of the vehicle. It
consists of an instrument cluster gauge connected to
the vehicle speed sensor on the transaxle output shaft.
The odometer measures the total distance the vehicle
has traveled since it was manufactured. It consists of an
instrument cluster gauge connected to the vehicle
speed sensor on the transaxle output shaft.
The trip odometer measures the distance the vehicle
has traveled since the odometer was last reset. It con-
sists of an instrument cluster gauge connected to the
vehicle speed sensor on the transaxle output shaft. The
trip odometer can be reset to zero at any time so that the
driver can record the distance traveled from any starting
point.
FUEL GAUGE
The fuel gauge consists of an instrument cluster gauge
connected to a sending unit in the fuel tank.
The fuel gauge indicates the quantity of fuel in the tank
without the ignition switch position.
TEMPERATURE GAUGE
The temperature gauge consists of an instrument clus-
ter gauge connected to a temperature sensor that is in
contact with the circulating engine coolant.
The temperature gauge indicates the temperature of the
coolant. Prolonged driving or idling in very hot weather
may cause the pointer to move beyond the center of the
gauge. The engine is overheating if the pointer moves
into the red zone at the upper limit of the gauge.
INSTRUMENT CLUSTER INDICATOR
LAMPS
The instrument cluster contains indicator lamps that in-
dicate the functioning of certain systems or the exis-
tence of potential problems with the operation of the
vehicle. The indicator lamps are replaceable. For re-
placement of the indicator lamps contained in the instru-
ment cluster, refer to “Instrument Cluster Indicator
Lamps Specifications” in this section.

IMMOBILIZER ANTI-THEFT SYSTEM 9T–11
DAEWOO M–150 BL2
The VIN code is calculated by the Immobilizer using a
random generator.
The VIN code is transmitted from the Immobilizer in the
release message communication only incase of using
an authorized key. Without an authorized key it is not
possible to getthe system VIN code.In case of ECM in-
ternal state is in Virgin mode or neutral mode the ECM
learns the system VIN code automatically after receiving
the first release response message.
To get a synchronized Immobilizer system (same VIN-
code in Immobilizer and ECM,authorized key) the DLC
test equipment has to be used for authorization of the
keys(first key coding). The usage of this test equipment
is restricted to authorized persons.

Communication with the DLC-test equipment. Main
functions are the key coding procedure, the VIN-code
handling and the support for system test functions.

Handling of the software watchdog
Operation
In the active mode of immobilizer (engine OFF, IG key
OFF) the status LED is blinking as mode A. When igni-
tion is turned ON, the system wakes up and tries to read
out the transponder.
In case of the detection of a valid key , The release mes-
sage communication with the ECM takes place. The sta-
tus LED displays the Immobilizer state “valid key”.
After turning off the ignition(ignition OFF detection simi-
lar to the ECM ignition OFF detection), the Immobilizer
changes to the active mode. The status LED is blinking
as Mode A.
Data Link Connector (DLC) Mode
When the ignition is on, a scan tool can switch the immo-
bilizer control unit to the DLC mode for diagnostics, key
coding and ID coding.

The status LED is turned off during DLC-mode

The Immobilizer will answer all correct messages,
which are defined as Immobilizer messages.
ID Code Handling
One of 65,535 VIN codes is stored in the immobilizer
EEPROM.
The VIN code can be erased by using “Reset VIN code”
command of the scan tool.
When the immobilizer control unit calculates a new VIN
code, ECM VIN code should be reset to get identical
with the immobilizer control unit’s.
During diagnostic procedures, the VIN code can be read
for comparison with the ECM VIN code by using the
scan tool’s “Read immobilizer control unit VIN code”
command.
SERIAL DATA LINK
Serial data can be exchanged between a scan tool and
the ECM and the Immobilizer control unit. The scan tool
connection is the data link connector (DLC).
ELECTRONIC CONTROL MOUDLE
(ECM)

ECM in Virgin mode
In this mode, the ECM knows only the model vehicle
identifier code.
The engine can be locked/unlocked.
ECM requests to ICU the VIN number. As soon as the
ECM receives two correct consecutive communica-
tion frames with the same VIN code the ECM learns
it.
The VIN code will be stored in non-volatile memory at
the end of power latch phase. ECM enters in Learnt
mode.

ECM in Learnt mode
In such a state, ECM checks on every communica-
tion, the correct encoding of the ICU.
If the code received is not correct, then the vehicle is
immobilized.
The coded 5 bytes of data emitted by ECM are a mix-
ture of MIN code and random.
The coded 5 bytes of data emitted by ICU are a mix-
ture of VIN code and random.

ECM in Neutral mode
This mode is a special intermediate mode, used for
ICU replacement or immobilizer option installation.
ECM request to ICU the VIN number. As soon as the
ECM receives two correct consecutive communica-
tion frames with the same VIN code the ECM learns
it. The VIN code will be stored in non-volatile memory
at the end of power latch phase. ECM enters in
Learnt mode.

After turning on the ignition the ECM will control the
engine in a normal way for starting and running while
waiting for a valid release response message from
the Immobilizer.
1. After receiving a response message including the in-
formation “ICU in learnt mode” and the correct sys-
tem VIN-code
→ the ECM enters the release state, which allows to
continue the running of the engine.
2. After receiving a response message including the in-
formation “ICU in learnt mode” and a wrong system
VIN-code
→ the ECM does not send a new request and enters
the blocked state, which causes the activation of the
immobilization actions of the engine.

DAEWOO M–150 BL2
6. Turn the ignition OFF and ON again, but do not
crank or start the engine. The ECM will reset the
ECM ID code to match the new ID code that was
calculated and sent by the immobilizer control unit
when the ignition was first turned ON after the reset
command.
7. Return the system to the normal mode.
8. Turn OFF the ignition.
9. Turn ON the ignition.
10. Start the engine.
After reprogramming the ID code, the scan tool SYS-
TEM DIAGNOSIS command can verify that the ECM ID
code matches the immobilizer control unit ID code.
If the reprogramming procedure does not result in
matching ID codes, check the electrical connectors for
the serial data wire between the immobilizer control unit
and the ECM.
TRANSPONDER
Each valid ignition key has an internal transponder
which is a read /write transponder.
The transponder contains an implementation of a cryp-
to-algorithm with 96 bits of user configurable secret-key
contained in EEPROM and transmits data to the ICU by
modulating the amplitude of the electromagnetic field,
and receives data and commands in a similar way.
