System conditions display function
-
• The air bag system detects each part condition and the SAS control module sends the system status signal to the instrument cluster.• The instrument cluster notifies the user of the system conditions using the following warning light based on the system condition signal.

Operation
Collision from front of vehicle or frontal offset
1.When an impact from a frontal or frontal offset collision (1) is received, the crash sensor built into the crash zone sensor and the crash sensor (2) built into the SAS control module detect the impact and convert the impact into an electrical signal at the signal processing circuit (3).
2.The SAS control module calculates (6) the degree of impact using the determination and safing circuit (5) based on the electric signal (4) from each crash sensor.
3.If the calculated degree of impact exceeds the previously set threshold, the SAS control module outputs (8) an operation (deployment) signal to each air bag module or pre-tensioner seat belt at the output control circuit (7).
4.Each air bag module or pre-tensioner seat belt operates (deploys) (9) based on the operation (deployment) signal from the SAS control module.

Collision from side of vehicle
1.When an impact (1) from a lateral collision is received, the following sensors (2) detect the impact and convert the impact or the pressure into an electrical signal at the signal processing circuit (3).
-
― Crash sensor integrated into side air bag sensor― Crash sensor integrated into SAS control module― Pressure detection sensor integrated into pressure sensor
2.The SAS control module calculates (6) the degree of impact using the determination and safing circuit (5) based on the electric signal (4) from each crash sensor or the pressure detection sensor.
