• If the seat belt switch is defective, the SRS-ECU determines that the seat belt is fastened and controls the seat belt with pre-tensioner.
• If the seat slide sensor is defective, the SRS-ECU determines that the seat is in its backward position and controls the air bag.
• If the occupant classification sensor or the occupant classification-ECU is defective, the SRS-ECU determines that the occupant classification is class 2 {The occupant classification sensor detects 30 kg (66 pounds) or more.} and controls the air bag and the passenger's air bag OFF indicator light.
