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 the airbag sensor.
e. If engine is run immediately after reconnecting negative battery terminal cable, keep it at less than 2000rpm for at least 1 minute.
f. If the engine exceeds 2,000rpm, the clutch is automatically disengaged by the compressor protection control system.
2. INSPECTION PROCEDURE FOR VEHICLE INVOLVED IN ACCIDENT
a. When the airbag has not deployed, check for DTCs by checking the SRS warning light blinking patterns or using a hand-held tester. If any DTCs are present, perform troubleshooting for those DTCs.
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 if any of the following conditions apply.
- The occupant classification ECU is replaced.
- Accessories (seat back 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 equipped with the passenger seat. If the flatness is not within (+) 3.0 mm (0.118 in.), adjust it to the specified range.
