Air Bag Systems: Description and Operation

DESCRIPTION

The air bag deploys when any of the two sensors (front crash zone sensor or tunnel sensor) and the sating sensor simultaneously activate while the ignition switch is "ON".









Self-diagnosis

The control unit (diagnostic unit) diagnoses the SRS circuit. When the ignition key is in the "ON" or "START" position, the "AIR BAG" warning lamp will illuminate for about 7 seconds and then turn off.
This means that the system is operational.
