B00A0:09, B00A0:4A, B00A0:63, B00A0:64 and B00A0:68

Refer to OEM Wiring Diagrams - SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.

The RCM is in constant communication with various control modules on the HS-CAN . One of those modules is the OCSM . The RCM continuously monitors the HS-CAN for fault messages reported by the OCSM. The RCM also checks for the correct identification of the OCSM . If the RCM receives fault message(s) from the OCSM system, it stores DTC B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

DTC FAULT TRIGGER CONDITIONS DESCRIPTION

DTC	Description	Fault Trigger Conditions
B00A0:09	Occupant Classification System: Component Failures	A fault is indicated when the RCM receives a message from the OCSM that a fault exists within the OCS .
B00A0:4A	Occupant Classification System: Incorrect Component Installed	A fault is indicated when the RCM senses the OCSM is present but not configured. This fault also sets if the incorrect OCSM or RCM are installed in the vehicle.
B00A0:63	Occupant Classification System: Circuit/Component Protection Time-Out	A fault is indicated when the RCM receives 8 or more invalid states from the OCSM .
B00A0:64	Occupant Classification System: Signal Plausibility Failure	A fault is indicated when the RCM receives messages containing upper or lower data limits other than limits stored in memory.
B00A0:68	Occupant Classification System: Event Information	A fault is indicated when the RCM receives a message from the OCSM that indicates an OCS fault is present.
