SRS AIR BAG SYSTEM

SYSTEM DESCRIPTION

SRS AIR BAG SYSTEM

SRS Configuration

INFOID:0000000009482972

The air bag deploys if the air bag diagnosis sensor unit is activated while the ignition switch is in the ON or

START position.

The collision modes for which supplemental restraint systems are activated are different among the SRS sys-

tems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-tension-

ers are activated in a frontal collision but not in a side collision.

SRS configurations for some collision modes are as follows:
