DAEWOO M-150 BL2
If there is a failure of the sensing and diagnostic module
or the external circuits, the SIR warning lamp in the in-
strument cluster turns ON.
As a system check, the SIR warning lamp also turns ON
when the ignition is first switched to the ON position.
Correct Functioning
The system is working properly if:

The SIR warning lamp turns OFF after approximately
four seconds.
Faulty Functioning
The system is not working properly, meaning one of the
SIR components or the wiring connector is faulty, if:

The SIR warning lamp fails to turn ON when the
ignition is first switched ON.

The SIR warning lamp remains ON.

CLOCK SPRING
The clock spring:

Is on the steering column.

Contains a coil that is the electrical contact between
the steering column wiring harness and the driver
side airbag module.

Is part of the circuit for the horn.
Notice: Turning the steering wheel more than three and
one-quarter turns may damage the clock spring.
Turning the steering wheel:

In one direction tightens the coil.

In the opposite direction loosens the coil.

More than three and one-quarter turns may damage
the clock spring.
Caution: Disassembling the clock spring can cause
injury and vehicle damage.The clock spring should never be disassembled.
The clock spring must be replaced if the airbags have
been deployed.
D110B008A
WIRING HARNESS/CONNECTORS
The connector for the sensing and diagnostic module
(SDM) has a built-in shorting bar that will turn ON the
warning lamp if there is a poor connection at the SDM.
As an anti-deployment mechanism, additional shorting
bars are in the

Connector for the clock spring at the lower steering
column.

Passenger airbag module connector.

SDM connector.
When these connectors are separated, the shorting
bars will short circuit any current which is applied, pre-
venting the current from reaching the airbag modules.
SIR SYSTEM
The supplemental inflatable restraints (SIR) system is a
safety device used in conjunction with the seat belts.
The airbag does not replace the function of the seat belt.
The driver and the passengers must always fasten their
seat belts and adjust them for a proper fit.
The SIR is designed to protect the driver and the front
seat passenger in the event of a significant frontal im-
pact to the vehicle. The airbags deploy if the force is ap-
plied from a direction within 30 degrees of the vehicle’s
centerline and above 25 km/h (15 mph) speed.
The SIR consists of a

Driver airbag module.

Passenger airbag module.
