SAS CONTROL MODULE FUNCTION [TYPE A]

id0810001010k3

Note
•  The SAS control module type differs depending on whether the DSC combined sensor is integrated.
―  Type A: Separate combined sensor (3 module connectors)
―  Type B: Built-in combined sensor (2 module connectors)

Crash Sensor

•  Crash sensor is built into the SAS control module.
•  If the degree of impact detected by the crash zone sensor and 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 No. 1 or No. 2 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.

Backup Power Supply Function

•  The backup power supply function enables the condenser to discharge and supply power to 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.

Configuration Function

•  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.
