This Diagnostic Trouble Code (DTC) will set if the Occupant Restraint Controller (ORC) is not configured for the Occupant Classification Module (OCM) and the OCM is active on the CAN Bus. Note: Because all ORCs are originally configured for the OCM the ORC must learn the not equipped with OCM state from the Front Control Module (FCM).
