Compatibility / Fitment

Function And Service Notes
The right rear side airbag is part of the vehicle Supplemental Restraint System (SRS). In a side impact event the airbag deploys to reduce risk of injury to rear seat occupants by cushioning and limiting lateral movement. Airbags are single-use safety devices: once deployed they must be replaced. The module contains the inflation device, airbag cushion and electrical connector that interfaces with the vehicle SRS wiring and sensors.
Common Failure Causes
- Deployment After Collision: Primary cause. Any airbag that has deployed must be replaced.
- Water Ingress Or Corrosion: Moisture in seat or body cavities can corrode connectors or trigger faults.
- Damage During Previous Repairs: Incorrect removal or damaged wiring/connectors can produce SRS faults.
- Connector Or Wiring Faults: Broken pins, chafed wires, or poor grounding causing open or short circuits.
- Sensor Or Control Unit Faults: Faults elsewhere in the SRS can make an airbag appear faulty even if the unit itself is intact.
Replacement Interval
There is no routine replacement interval for airbags. Replace the airbag if it has deployed, if the unit or its connector is damaged, or if the vehicle diagnostic system indicates a fault specific to the right rear side airbag. After replacement, clear SRS fault codes and confirm system readiness with a diagnostic tool.
Installation Recommendations
- Always Disconnect The Battery: Before starting work, disconnect the negative battery terminal and wait at least 10 minutes to allow SRS energy capacitors to discharge.
- Follow Manufacturer Procedures: Remove trim panels and seat components carefully to avoid damaging the airbag or wiring.
- Handle Airbag Modules With Care: Store with the airbag cushion facing upward and avoid impact or exposure to heat.
- Use Correct Fasteners And Torque: Refit using the original fasteners and tighten to the Manufacturer Recommended Torque.
- Clear And Verify SRS Codes: After installation, use an appropriate diagnostic tool to clear faults and perform system checks. If an SRS warning remains, troubleshoot wiring, connectors and related sensors.
- Professional Installation Recommended: For safety-critical systems such as airbags, installation by a trained technician is strongly advised.
