Occupant Classification Undetermined Status

OCCUPANT CLASSIFICATION UNDETERMINED STATUS

Theory of Operation

The Occupant Classification Module (OCM) broadcasts a status message on the Bus that provides OCM status and system fault data to the Occupant Restraint Controller (ORC). The ORC uses the fault data message to command the Airbag Warning Lamp ON and OFF. The ORC also uses the occupant classification status message to set active OCCUPANT CLASSIFICATION UNDETERMINED STATUS DTC until the condition in the OCM is repaired.
