SRS AIR BAG SYSTEM : System Diagram

SRS AIR BAG SYSTEM : System Description

• 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 systems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-tensioners are activated in a frontal collision but not in a side collision.
