PRECAUTION1. HANDLING PRECAUTIONS FOR AIRBAG SENSOR
HINT: In this section, the airbag sensor assembly, front airbag sensor LH, front airbag sensor RH, side airbag sensor assembly LH, side airbag sensor assembly RH, curtain shield airbag sensor assembly LH, curtain shield airbag sensor assembly RH and seat position airbag sensor assembly are collectively referred to as the airbag sensor.
a. Before starting the following operations, wait at least 90 seconds after disconnecting the negative (-) terminal of the battery:
1. Replacement of the airbag sensor.
2. Adjustment of the front/rear doors of the vehicle equipped with the side airbag and curtain shield airbag (fitting adjustment).
b. When connecting or disconnecting the airbag sensor connector, ensure that all of the sensors are installed in the vehicle.
c. Do not use an airbag sensor which has been dropped during the operation or transportation.
d. Do not disassemble an airbag sensor.
2. INSPECTION PROCEDURE FOR VEHICLE INVOLVED IN ACCIDENT
a. When an airbag has not deployed, confirm the DTC by checking the SRS warning light. If there is any malfunction in the SRS airbag system, perform troubleshooting.
b. When any of the airbags have deployed, replace the airbag sensor and check the installation condition.
c. Perform the zero point calibration and sensitivity check under the conditions listed below
- The occupant classification ECU is replaced.
- Accessories (seatback tray, seat cover, etc.) are installed.
- The passenger seat is removed from the vehicle.
- The passenger airbag ON/OFF indicator ("OFF") comes on when the passenger seat is not occupied.
- The vehicle is brought to the workshop for repair due to an accident or a collision.
NOTE:
- When an accident vehicle is brought into the workshop for repair, check the flatness of the body side that is installed on the passenger seat. If the flatness is not within ± 3.0 mm (0.118 in.), repair it to the specified range (within ± 3.0 mm (0.118 in.)).
- The sensitivity check method differs according to the front seat type (separate seat and bench seat, split seat).
