Supplemental Restraint System Control Module (SRSCM)
WARNING: This page is about a different car, the 2002 Kia Sedona. However, it is still accessible from the selected car via links, so may be relevant.
SRSCM monitors vehicle velocity changes to detect frontal impact which are severe enough to warrant air bag module deployment. When a frontal impact of sufficient force is detected, SRSCM causes current flow through driver-side and passenger-side air bag modules and seat belt pretensioners, causing deployment of components.
Additionally, SRSCM provides diagnostic monitoring of SIR system electrical components. When a malfunction is detected, SRSCM sets a Diagnostic Trouble Code (DTC) which can be retrieved using a scan tool. SRSCM warns driver of system malfunctions by controlling AIR BAG warning light.
