Air Bag Systems: Description and Operation

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

SRS Configuration:

Description
The air bag deploys if the diagnosis sensor unit activates 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 systems. For example, the driver air bag module and front passenger air bag module are activated in a frontal collision but not in a side collision.

SRS configurations which are activated for some collision modes are as shown in image.
