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, gas generator, 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, gas generator, 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, gas generator, etc., and inflates the bag when instructed by the side airbag sensor assembly.




5. CURTAIN SHIELD AIRBAG ASSEMBLY
The inflater and bag of the SRS are stored in the curtain shield airbag assembly and cannot be disassembled. The inflater contains a squib, igniter charge, gas generator, etc., and inflates the bag when instructed by the airbag sensor assembly.




6. FRONT SEAT BELT PRETENSIONER
The front seat belt pretensioner system is a component of the front seat outer belt. The pretensioner contains a squib, gas generator, wire, piston, etc., and operates in the event of a frontal collision. The front seat belt pretensioner cannot be disassembled.




7. REAR SEAT BELT PRETENSIONER
The rear seat belt pretensioner system is a component of the rear seat outer belt. The pretensioner contains a squib, gas generator, wire, piston, etc., and operates in the event of a frontal collision. The rear seat belt pretensioner cannot be disassembled.




8. 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 self-diagnosis. In normal operation conditions when the ignition switch is turned to the ON position, the light goes on for about 6 seconds and then goes off.




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




10. FRONT AIRBAG SENSOR
The front airbag sensor is mounted inside each of the side members. The front airbag sensor consists of a frontal deceleration sensor, diagnosis circuit, etc.. It sending a signal to the airbag sensor assembly. The front airbag sensor cannot be disassembled.




11. SIDE AND CURTAIN SHIELD AIRBAG SENSOR ASSEMBLY
The side and curtain shield airbag sensor assembly is mounted in the LH and RH center pillars. The side and curtain shield airbag sensor assembly consists of a lateral deceleration sensor, safing sensor, diagnosis circuit, etc.. It sends signals to the airbag sensor assembly to judge whether the SRS side airbag and curtain shield airbag must be activated or not. The side and curtain shield airbag sensor assembly cannot be disassembled.




12. CURTAIN SHIELD AIRBAG SENSOR ASSEMBLY
The curtain shield airbag sensor assembly is mounted inside each of the quarter wheel panel. The sensor unit consists of a lateral deceleration sensor, diagnosis circuit, etc.. It sends signals to the airbag sensor assembly to judge whether the SRS curtain shield airbag must be activated or not. The curtain shield airbag sensor assembly cannot be disassembled.




13. SEAT POSITION SENSOR ASSEMBLY
The seat position sensor assembly is mounted on the seat rail of the driver's seat. The sensor unit consists of a magnet sensor, diagnosis circuit, etc.. It judges the seat sliding position and sends the signal to the airbag sensor assembly. The seat position sensor assembly cannot be disassembled.
