SIR Airbag Warning Indicator -
The supplemental inflatable restraint (SIR) system supplements the protection offered by the occupant seat belt system. The SIR system has several inflater modules located throughout the vehicle, i.e. The inflatable restraint steering wheel module, inflatable restraint IP module in passenger side of dash, and the inflatable restraint side impact module - LF and RT. Each inflator module has a deployment loop that is controlled by the inflatable restraint Sensing and Diagnostic Module (SDM), which is mounted inside of the vehicle. A problem in any part of the system will turn on the light.
