Seat Occupant Sensor: Service Precautions

PRECAUTION

CAUTION: Do not use seat accessories (such as cushions or covers) that cover the front seat. Also, do not modify or replace the upholstery of the front seat. Doing so may prevent the front passenger airbag system from activating correctly, disable the system or cause the front passenger airbag to inflate accidentally, and result in death or serious injury.

NOTE: Replace the occupant classification ECU, occupant classification sensor, seat cushion cover pad, seat cushion cover and seat cushion seat heater as a 5 part set.

1. INSPECTION PROCEDURE FOR VEHICLE INVOLVED IN ACCIDENT

a. Perform the zero point calibration and sensitivity check if any of the following conditions apply.
- The occupant classification ECU is replaced.
- Accessories (seatback tray, seat cover, etc.) are installed.
- The front passenger seat is removed from the vehicle.
- The passenger airbag ON / OFF indicator indicates OFF when the front passenger seat is not occupied.
- The vehicle is brought to the workshop for repair due to an accident or a collision.

NOTE: When a vehicle that has been in an accident is brought into the workshop for repair, check the flatness of the floor where the front passenger seat is mounted. If the flatness is not within ± 3.0 mm (0.118 in.), adjust it to the specified range.
