DUAL STAGE AIR BAGS AND SEAT BELT PRE-TENSIONER

Frontal collision against
another vehicle
or
Frontal collision against a
solid surface
SRS-ECU uses data of the front impact sensor (in engine compartment) and G-sensor (in SRS-ECU) to cal-
culate collision severity during frontal collision. SRS-ECU judges necessity of air bag based on the calculated
collision severity. In addition, the SRS-ECU also judges the operation of seat belt pre-tensioner after calculat-
ing collision severity. Alternatively, when the passenger's air bag cut off switch is set to the air bag off position,
the SRS-ECU illuminates the passenger's air bag OFF indicator lamp by disabling the deployment of passen-
ger's (front) air bag.
