Operation

Function Of Components


1. Steering Wheel Pad (with AIRBAG)





The inflater and bag of the SRS are stored in the steering wheel pad and cannot be disassembled. The inflater contains a squib, igniter charge, gas generant, etc.. and inflates the bag when instructed by the center airbag sensor assembly.



2. Spiral Cable (in Combination Switch)





A spiral cable is used as an electrical joint from the vehicle body side to the steering wheel.

3. Front Passenger Airbag Assembly





The inflater and bag of the SRS are stored in the front passenger airbag assembly and cannot be disassembled. The inflater contains a squib, ignite charge, gas generant, etc.. and inflates the bag when instructed by the center airbag sensor assembly.

4. SRS WARNING LIGHT





The SRS warning light is located on the cluster finish panel. It goes on to alert the driver of trouble in the system when a malfunction is detected in the center airbag sensor assembly. In normal operating conditions when the ignition switch is turned to the ACC or ON position. the light goes on for about 6 seconds and then goes off.

5. FRONT AIRBAG SENSOR





A front airbag sensor is mounted inside each of the front fenders. The sensor unit is a mechanical type. When the sensor detects a deceleration force above a predetermined limit, contact is made in the sensor sending a signal to the center airbag sensor assembly.The sensor cannot be disassembled.


6. Center Airbag Sensor Assembly





The center airbag sensor assembly is mounted on the floor inside the console box. The center airbag sensor assembly consists of a center airbag sensor. safing sensor, diagnosis circuit and ignition control. drive circuit. etc. It receives signals from the airbag sensors and judges whether the SRS must be activated or not.

7. SRS CONNECTORS










All connectors in the SRS are colored yellow to distinguish them from other connectors. Connectors having special functions and specifically designed for SRS are used in the locations shown to ensure high reliability. These connectors use durable gold-plated terminals.






When the vehicle is involved in a frontal collision in the hatched area shown in image and the shock is larger than a predetermined level, the SRS is activated automatically. A safing sensor is designed to go on at a smaller deceleration rate than the front and center airbag sensors. As illustrated, ignition is caused when current flows to the squib, which happens when a safing sensor and a front airbag sensor and/or the center airbag sensor go on simultaneously. When a deceleration force acts on the sensors, two squibs in the driver airbag and front passenger airbag ignite and generate gas. The gas discharging into the driver and front passenger airbags rapidly increases the pressure inside the bags, breaking open the steering wheel pad and instrument panel door. Bag inflation then ends. and the bags deflate as the gas is discharged through discharge holes at the bag's rear or side.
