Curtain airbags are installed inside the headliner (LH and RH) and protect the driver and passenger from danger when a side crash occurs. The SRSCM determines deployment of the curtain airbag by using the side impact sensor (SIS) signal.

  

Never attempt to measure the circuit resistance of the airbag module even if you are using a specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.
