Air Bag System





SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: PRECAUTION

CAUTION:
- The vehicle is equipped with a Supplemental Restraint System (SRS). It consists of a driver airbag, front passenger airbag, driver side knee airbag, front passenger side knee airbag, side airbag, curtain shield airbag, rear side airbag, front seat belt pretensioner and rear seat belt pretensioner. Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Further, if a mistake is made in servicing the SRS, it is possible that the SRS may fail to operate when required. Before performing servicing (including removal or installation of parts, inspection or replacement), be sure to read the following items carefully, then follow the correct procedures indicated in the repair manual.
- Wait at least 90 seconds after the engine switch is turned off and the negative (-) terminal cable is disconnected from the battery before starting the operation.
- (The SRS is equipped with a backup power source, so that if work is started within 90 seconds after disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed).
- Do not expose the steering pad, front passenger airbag assembly, driver side knee airbag assembly, front passenger side knee airbag assembly, center airbag sensor assembly, front airbag sensor, front seat inner belt assembly, seat position airbag sensor, occupant classification ECU, front seat airbag assembly, side airbag sensor, curtain shield airbag assembly, rear seat airbag assembly, rear airbag sensor, front seat outer belt assembly or rear seat outer belt assembly directly to hot air or flames.
NOTICE:
- Malfunction symptoms of the SRS are difficult to confirm, so DTCs are the most important source of information when troubleshooting. When troubleshooting the SRS, always inspect DTCs before disconnecting the battery.
- Even in the case of a minor collision when the SRS does not deploy, the steering pad, front passenger airbag assembly, driver side knee airbag assembly, front passenger side knee airbag assembly, center airbag sensor assembly, front airbag sensor, front seat inner belt assembly, seat position airbag sensor, occupant classification ECU, front seat airbag assembly, side airbag sensor, curtain shield airbag assembly, rear seat airbag assembly, rear airbag sensor, front seat outer belt assembly or rear seat outer belt assembly should be inspected.
- Before repair work, remove the airbag sensor if any kind of shock is likely to occur to the airbag sensor during the operation.
- Never use SRS parts from another vehicle. When replacing parts, replace them with new ones.
- Never disassemble or repair any of the following parts in order to reuse them. If any of these parts have been dropped, or a defect is found (e.g. cracks, dents or any other defects) in any of the housings, brackets or connectors, then replace the part with a new one.
- Steering Pad
- Front Passenger Airbag Assembly
- Driver Side Knee Airbag Assembly
- Front Passenger Side Knee Airbag Assembly
- Front Seat Airbag Assembly
- Curtain Shield Airbag Assembly
- Rear Seat Airbag Assembly
- Center Airbag Sensor Assembly
- Front Airbag Sensor
- Front Seat Inner Belt Assembly
- Seat Position Airbag Sensor
- Occupant Classification ECU
- Side Airbag Sensor
- Rear Airbag Sensor
- Front Seat Outer Belt Assembly
- Rear Seat Outer Belt Assembly
- Use a volt/ohmmeter with high impedance (10 kOhms/V minimum) for troubleshooting the electrical circuits.
- Information labels are attached near the SRS components. Follow the instructions in the caution.
- After work on the SRS is completed, perform the SRS warning light check Diagnosis System.
- When the negative (-) terminal cable is disconnected from the battery, the memory will be cleared. Because of this, be sure to make a record of the contents memorized in each system before starting work. When work is finished, adjust each system as it was before. Never attempt to avoid erasing vehicle system memory by using a backup power supply from outside the vehicle.
- If the vehicle is equipped with a mobile communication system, refer to the precaution in the INTRODUCTION section.
- When disconnecting the negative (-) battery cable, initialize the following systems after the cable is reconnected.






HINT
In the airbag system, the center airbag sensor assembly, front airbag sensor LH and RH, side airbag sensor LH and RH, rear 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.
