The air bag module, located in the center of the steering wheel, contains a folded air bag and an inflator unit.
The spiral cable, located in the steering column, ensures an uninterrupted electrical circuit to the air bag module, while allowing rotation of the steering wheel. This cable is sometimes referred to as a clockspring.
The warning lamp, located in the instrument panel, indicates operational status of the SRS.
The SRS control unit, monitors the SRS system and stores data, should any faults be detected in the system.
The SRS system connectors use a double lock mechanism and a coupling error detection system. If the connector is not properly connected, the air bag warning light will illuminate on the instrument cluster.
The proper method for using these connectors is to press the release tab on the connector until the green lever pops up, this will unlock the connector. Then pull the connector apart while pushing the lever down. To reconnect the connectors, push the halves together until a click is heard then push the green lever down until another click is heard.
