The Occupant Classification System Module (OCSM) monitors each Occupant Classification System (OCS) weight sensor bolt and circuitry for faults. If the OCSM detects an upward force (obstruction) on the passenger seat for 60 seconds, it will store DTC B00A0:97 in memory and send a message to the Restraints Control Module (RCM).

The RCM will store DTC B00A0:09 in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
