Side air bag system
1. During a lateral collision to the vehicle, the crash sensors in the side air bag sensor and SAS unit detect the
collision.
2. The degree of impact detected by the crash sensor in the side air bag sensor is converted to an electrical signal
and sent to the SAS unit through the signal amplification circuit.
3. Simultaneously, the SAS unit crash sensor converts the degree of impact detected to an electrical signal.
4. The SAS unit processes the calculations for the two electrical signals at the ouput control circuit and compares
the value to a preset value.
5. The output control circuit determines the degree of impact to the vehicle by the value from the crash sensors,
completes a side air bag module and curtain air bag module ignition circuit, and sends the deployment signal to
the air bag modules.

Module configuration
Function
• Module configuration is performed to provide an initial setting for the SAS unit according to the actually
equipped air bag module, pre-tensioner seat belt and occupancy sensor.
• If there is a mismatch between the air bag system configuration and the initial setting for the SAS unit, a DTC is
displayed.
• The module configuration is performed using only the SST (WDS or equivalent).
