•  Crash sensor is built into the SAS control module.

•  If the degree of impact detected by the crash sensor built into the SAS control module exceeds the set value during a frontal collision to the vehicle, the SAS control module sends an operation (deployment) signal to the air bag module and the pre-tensioner seat belts.

•  If the degree of impact detected by side air bag sensor and the crash sensor built into the SAS control module exceeds the set value during a side collision to the vehicle, the SAS control module sends an operation (deployment) signal to the side air bag module and curtain air bag module.

•  The backup power supply stores energy in a big capacitor. This energy assure air bag system operation/deployment properly for a specified time even if the power supply to the SAS control module is cut due to a collision.

•  Identifies the variation of the air bag module installed to the vehicle when replacing the SAS control module with a new one.

•  If the air bag module installed to the vehicle and the module identified by the SAS control module differ, a DTC is displayed.

•  Refer to the Workshop Manual for the configuration setting procedure.
