SYSTEM OPERATION

ADVANCED AIR BAG AND SEAT BELT WITH PRE-TENSIONER

M2521000700435

• In case of a frontal collision, when the front 

impact sensor inside the engine room and the 
G-sensor inside SRS-ECU simultaneously detect 
an impact that exceeds a certain threshold 
(turned ON), SRS-ECU energizes the driver's 
and passenger's (front) air bag modules (squibs), 
knee air bag module (squib) and driver's and pas-
senger's seat belt pre-tensioners (squibs), thus 
deploying the air bags and triggering the seat belt 
pre-tensioners. Also, the advanced air bag has 
been adopted to optimize the air bag deployment 
control by adjusting the inflation pressure.

• The seat slide sensor to detect the driver's seat 

position judges the deployment in two stages, 
and deploys the driver's air bag.

• The occupant classification-ECU has been added 

to recognize the passenger's seat occupant. The 
occupant classification-ECU identifies the occu-
pant class based on the signals from weight sen-
sors, and sends the signal to SRS-ECU.
