A front air bag sensor is mounted inside each of the front fenders. The sensor unit is basically a mechanical switch. When the sensor detects a deceleration force above a predetermined level in a collision, the contacts in the sensor close, sending a signal to the center air bag sensor assembly. The sensor cannot be disassembled. If the front fenders on the vehicle are damaged in any way, do a visual check of the sensors even if the air bag is not deployed. Inspect for:

The center air bag sensor is mounted on the floor inside the console box. The air bag sensor determines whether or not the air bag should be deployed and is also used to diagnose system malfunction.

The spiral cable, part of the combination switch, is used as an electrical joint from the vehicle body to the steering wheel. The spiral cable is referred to as a clock spring.
The driver's air bag, located in the steering wheel pad, contains a gas generant which will rapidly inflate the bag in a case of frontal collision.

The inflator and bag of the SRS are located in the front of the passenger's air bag assembly and can not be disassembled. The air bag will inflate only when the sensor instructs it to do so.

The air bag SRS warning lamp, located on the combination meter, is used to alert the driver of any malfunctions within the air bag system. In normal operating conditions when the ignition switch is turned to the ON or ACC, the light goes on for about 6 seconds and then goes off.

All connectors in the SRS are colored yellow to distinguish them from the other connectors. These connectors have special functions are specifically designed for the SRS. These connectors use durable gold-plated terminals.
