Some 2012 Toyota Camry and Camry HV vehicles may exhibit a condition where the passenger AIRBAG OFF light may illuminate intermittently while driving with the passenger seat unoccupied.
According to Toyota, this condition will not affect airbag operation. An updated Occupant Classification System Electronic Control Unit (OCS ECU) has been made available to address this condition. This updated OCS ECU logic will now illuminate the AIRBAG OFF light at all times when the vehicle is operated and the passenger seat is unoccupied or when the OCS ECU determines that the occupant does not meet the adult classification criteria.
