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.




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.




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.




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.
