PARTS THAT MUST BE REPLACED FOLLOWING A DEPLOYMENT

When the SRS parts are deployed (including when only an airbag or pretensioner is deployed) due to a collision, be sure to replace all sensors in the damaged areas (anywhere in need of repair) and airbag ECU assembly (center airbag sensor).

Replace all sensors in the damaged areas and airbag ECU assembly:
• Airbag ECU assembly (center airbag sensor) [MODULE,AIRBAG CONTROL]
• Front airbag sensors [AIRBAG SENSOR,FRONT]
• Door side airbag sensors [AIRBAG SENSOR,FRT DOOR]
• Side airbag sensor assemblies [AIRBAG SENSOR,QTR PANEL]
• Rear airbag sensors [AIRBAG SENSOR,QTR PANEL]

[Delpoyed] SRS parts:
• Horn button assembly [AIRBAG,STEERING WHEEL]
• Lower No. 1 instrument panel airbag assembly [AIRBAG,KNEE BOLSTER]
• Lower No. 2 instrument panel airbag assembly [AIRBAG,KNEE BOLSTER]
• Instrument panel passenger airbag assembly [AIRBAG,INSTRUMENT PNL]
• Curtain shield airbag assemblies [AIRBAG,ROOF]
• Front seat airbag assemblies [AIRBAG,FRONT SEAT]

• If a front seat airbag assembly has been deployed, replace the front seat airbag assembly, front seatback frame sub-assembly and front seatback pad with cover with the necessary parts in accordance with the extent of the collision damage

PARTS THAT MUST BE INSPECTED AND REPLACED IF DAMAGED

When troubleshooting the SRS, always check for DTCs before disconnecting the cable from the negative (-) battery terminal

In the airbag system, the parts listed below are collectively referred to as the airbag sensors:
• Airbag ECU assembly (center airbag sensor)
• Front airbag sensors
• Door side airbag sensors
• Side airbag sensor assemblies
• Rear airbag sensors

The parts listed below are collectively referred to as the SRS parts:
• Horn button assembly
• Lower No. 1 instrument panel airbag assembly
• Lower No. 2 instrument panel airbag assembly
• Instrument panel passenger airbag assembly
• Curtain shield airbag assemblies
• Front seat airbag assemblies
• Front seat outer belt assemblies
• Rear seat 3 point type outer belt assemblies

Visually check the airbag sensors in undamaged areas for defects:
• If any defects are found or an airbag sensor has detected a major collision, replace the airbag sensor with a new one

• Before using an electric welder on the vehicle, remove any SRS parts around the area being repaired
• Before repairs, remove the airbag sensor assemblies if impacts are likely to be applied to the sensor during repairs
• As the SRS parts are very hot after being deployed, ensure that all wire harnesses and connectors around deployed SRS parts are not damaged
• Inspect SRS parts when the vehicle is damaged in a collision even when the SRS parts are not deployed

Perform zero point calibration and sensitivity check if any of the following conditions occur:
• The occupant detection ECU is replaced
• The front passenger seat is removed from the vehicle
• One of the bolts that is used to install the front passenger seat is removed and reinstalled
• The vehicle is brought to the workshop for repair due to an accident or a collision

Replace any faulty parts of the seat belt systems (outer belt, inner belt, bolts, nuts, tether anchor hardware and other related parts). When inspecting a vehicle that has been involved in a collision, be sure to check all of the seat belt systems regardless of whether or not the system was activated in the collision. Replace any damaged or malfunctioning systems
