Supplemental Restraint System (SRS): Overview
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The Restraints Control Module (RCM ) continually receives and monitors inputs from the OCSM and various other hardwired switches and sensors. If the RCM detects a sudden vehicle deceleration and/or lateral deceleration based on the information received from the various sensors, and determines that deployment is necessary, the RCM applies voltage and current to deploy the appropriate Supplemental Restraint System (SRS) components.
