Repairs and Inspections Required After a Collision: Service and Repair

SUPPLEMENTAL RESTRAINT SYSTEM: OCCUPANT CLASSIFICATION SYSTEM: 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.

NOTICE:
- 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 (see supply set part no.).
- When disconnecting the cable from the negative (-) battery terminal, initialize the following system (s) after the cable is reconnected.






1. INSPECTION PROCEDURE FOR VEHICLE INVOLVED IN ACCIDENT

(a) Perform zero point calibration and sensitivity check if any of the following conditions apply Initialization.

- The occupant classification ECU is replaced.

- 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.

- For minor collisions where SRS parts do not deploy, always inspect the SRS parts.
- Before repair work, remove airbag sensors as necessary if any kind of impact is likely to occur to an airbag sensor during the operation.
- Never use SRS parts from another vehicle. When replacing SRS parts, replace them with new ones.
- Never disassemble or attempt to repair SRS parts.
- If an SRS part has been dropped, or if there are any cracks, dents or other defects in the case, bracket or connector, replace the SRS part with a new one.
- Use an ohmmeter / voltmeter with high impedance (10 kOhms/V minimum) for troubleshooting the electrical circuits.
- Information labels are attached to the periphery of SRS parts. Follow the cautions and instructions on the labels.
- After work on SRS parts is completed, perform the SRS warning light check Diagnosis System.
- When the cable is disconnected from the negative (-) battery terminal, the memory settings of each system will be cleared. Because of this, be sure to write down the settings of each system before starting work. When work is finished, reset the settings of each system as before. Never use a backup power supply from outside the vehicle to avoid erasing the memory in a system.
- When disconnecting the cable from the negative (-) battery terminal, initialize the following system(s) after the cable is reconnected.






HINT
In the airbag system, the center airbag sensor, front airbag sensor LH and RH, side airbag sensor LH and RH, and door side airbag sensor LH and RH are collectively referred to as the airbag sensors.

2. INSPECTION PROCEDURE FOR VEHICLE INVOLVED IN ACCIDENT

(a) When the airbag has not deployed, confirm the DTCs 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 sensors and check the installation condition.
