Supplemental information on involved component(s) from 2018-2020 Expedition Workshop Manual:
Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - Overview
The Restraints Control Module (RCM) continually receives and monitors inputs from the Occupant Classification System Module (OCSM) and various other hard-wired 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, it applies voltage and current to deploy the appropriate SRS components.
