General Description

SRS DESCRIPTION AND OPERATION




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 and gas generant, etc., and inflates the bag when instructed by the 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, igniter charge, and gas generant, etc., and inflates the bag when instructed by the airbag sensor assembly.




4. SIDE AIRBAG ASSEMBLY
The inflater and bag of the SRS side airbag are stored in the side airbag assembly and cannot be disassembled. The inflater contains a squib, igniter charge and gas generant, etc., and inflates the bag when instructed by the side airbag sensor assembly.




5. SEAT BELT PRETENSIONER
The seat belt pretensioner system is a component of the front seat outer belt. The pretensioner contains a squib, gas generant, wire, piston, etc., and operates in the event of a frontal collision.




6. SRS WARNING LIGHT
The SRS warning light is located on the combination meter. It goes on to alert the driver of trouble in the system when a malfunction is detected in the airbag sensor assembly. In normal operation 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.




7. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the lower center finish panel. The airbag sensor assembly consists of an airbag sensor, safing sensor, diagnosis circuit ignition control and drive circuit, etc. It receives signals from the airbag sensor, front airbag sensor and side airbag sensor and judges whether the SRS must be activated or not.




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




9. SIDE AIRBAG SENSOR ASSEMBLY
The side airbag sensor assembly is mounted in the LH and RH center pillars. The side airbag sensor assembly consists of a side airbag, sensor, safing sensor and diagnosis circuit, etc. It sends signals to the airbag sensor assembly to judges whether the SRS side airbag must be activated or not.




10. DOOR SIDE AIRBAG SENSOR
A door side airbag sensor is mounted on each of the door inside panel. The sensor unit is a mechanical type. When the sensor detects deceleration force above a predetermined limit, contact is made in the sensor, sending a signal to the airbag sensor assembly. The sensor cannot be disassembled.
