SAS CONTROL MODULE FUNCTION
id081000101000
Sensing Function
• crash, angular rate, and low-G sensors are 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.
• During vehicle rollover, the rollover determination is performed based on the results detected by the angular
rate and low-G sensors built into the SAS control 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.
