Mazda 6 Airbag Light Due to Occupant Classification Sensor Failure

This cause is suspected when the 'Passenger Airbag OFF' indicator illuminates alongside the main SRS warning light. Confirmation is achieved by reading specific DTCs that point to the OCS (Occupant Classification Sensor) module, often identified by a specific flash code pattern indicating a weight sensor fault, and verifying if the system fails to detect a passenger's weight correctly.
