Restraint Side Impact Sensing Modules

The Restraint Side Impact Sensing and Diagnostic Modules (SISM) provide reserve energy to the side impact deployment loops, and deploy their respective side air bag when required. The SISMs perform diagnostic monitoring of the side impact air bag system components and communicate the system status to the inflatable restraint Sensing And Diagnostic Module (SDM).
