4) Inflator
The inflator is a type of the direct gas generated device.
The inflator with initial low pressure provides negative restraint effect regarding passengers
moving and time.
On the contrary, the inflator with initial high pressure allows other components of the airbag
to make a excessive impact resulting in any personal injury.
Thus, the inflator output must be optimized according to the characteristic of the vehicle and
passenger moving.
The discharge gas has no toxicity or inflammability and also it is the important parameter to
control the high temperature for gas firing. ·

5) SDM (Sensing and Diagnostic Module)
The airbag system consists of the module section (driver, passenger and side), seat belt
section and SDM.
The SDM has no user-serviceable parts and monitors the system components continuously.
The SDM also records any faults which are discovered.
The SDM allows the fault codes to be retrieved with a scan tool and illuminates a warning
lamp that alerts the driver to any faults. 1.
2.
3.
The SDM located on floor beneath the floor console assembly. The SDM performs the
following functions:
Impact decision processor function.
Determine the airbag deployment through the impact signal of the accelerometer sensor and
the safety sensor. ·
·
Malfunction detection and recording any faults that are detected.
Monitor the supplemental restrain system electrical components and set a diagnostic trouble
code when malfunction is detected.
Display airbag fault codes Display airbag fault codes and system status information when
connected to a scan tool.
Self-diagnosis function Illuminate the AIRBAG indicator to alert the driver to any fault.
Power supply function Provide a reserve power source to deploy the airbags and
pretensioners if an accident has disabled the normal power source. ·

9) Micro Controller
This device receives the impact signal from the sensor for vehicle impact and identifies whether
the current condition is necessary for airbag deployment or not. And then the controller sends
the specified currents to the airbag ignition circuit as needed.
This device always monitors the airbag system in conduction with the diagnostic circuit. When it
is detected any problem, it illuminates the airbag warning indicator to inform driver of the fault
and stores the fault information.
10) Airbag Warning Lamp
The instrument cluster contains an airbag warning indicator bulb to verify the operation of the
AIRBAG indicator and sensing and diagnostic module (SDM).
The SDM performs a turn-on test when the ignition is turned ON. The SDM flashes the
AIRBAG
indicator seven tomes by supplying an intermittent ground to the indicator lamp circuit.
After
flashing seven times, the AIRBAG indicator will turn off if no more malfunctions have been
detected.

11) Wiring Harness Connectors
If the sensing and diagnostic module (SDM) electrical connector is not attached properly, a built
in shorting bar will connect the wire from airbag warning lamp with the SDM ground wire. This
turns on the AIRBAG indicator.
To prevent deployment during servicing, additional shorting bars are located in following
locations:
Driver airbag module connector
Passenger airbag module connector
Driver and passenger side airbag module connector
SDM wiring harness connector
Contact coil connector to airbag wiring harness ·
·
·
·
·
The shorting bar is only a backup safety device. Always disable the supplemental restraints
system (SRS) before beginning any service procedure.
12) Belt Pretensioner
The belt pretensioner enables to retract the driver and the passenger seat belt webbing to
reduce any personal impact when accounted a frontal collision.

50>
The air bag inflates when:
Frontal impact against a solid concrete wall at over 25 km/h or near-frontal impact
within 30 degrees from the center of the vehicle at both corners ·
The air bag can inflate when:
Underbody impact from the road surface; impact against the curb at a very high speed;
dropping impact onto the road surface with a large angle ·
The air bag does not inflate when:
Rollover, side impact or rear impact ·
The air bag seldom inflates when:
Weak impact in which the sensor is unable to detect (under the inflation requirements)
Impact against narrow objects such as a telegraph pole or a tree
The vehicle falls into a drainage or a puddle
The front of the vehicle crashes into high impact point vehicle such as a truck
Impact on the hood by falling stones
The air bag warning lamp is on ·
