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)
1. The airbag system consists of the module section (driver, passenger and side), seat belt
section and SDM.
2. The SDM has no user-serviceable parts and monitors the system components continuously.
The SDM also records any faults which are discovered.
3. 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.
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.
