Fitment And Compatibility

Function And Typical Failure Causes
The seat side airbag is a pyrotechnic safety device that inflates instantaneously during a side impact to reduce chest and pelvic injuries. Airbags do not wear out under normal conditions but become unusable when deployed in a crash. Common causes of non-function or damage include prior deployment, connector or wiring harness damage (often from seat movement), water ingress and corrosion, improper previous repairs, or electrical faults in the airbag circuit.
Replacement And Installation
Replacement should be performed by a qualified technician or an experienced mechanic following safety procedures. General replacement steps:
- Disconnect the negative battery terminal and wait at least 10 minutes for the system capacitors to discharge (follow vehicle manufacturer recommendations).
- Remove seat trim and access panels to reach the airbag connector and mounting points.
- Carefully unplug the airbag connector using the correct release method; avoid pulling on wiring.
- Unbolt the airbag module from the seat structure and remove the old unit.
- Install the replacement airbag, secure mounting bolts to the manufacturer specification and reconnect the connector ensuring a clean, corrosion-free contact.
- Reassemble trim and restore the battery connection.
- Use an appropriate diagnostic tool to clear airbag fault codes and confirm system readiness.
Installation Recommendations
Handle the airbag module with extreme care—store it with the deployment side facing up and keep away from heat sources and static. Do not attempt repairs on the inflator or cushion. Replace any damaged connectors or seat wiring harness sections. After installation, always perform a full airbag system check with a suitable diagnostic interface to ensure no fault codes remain and the system reports as operational.
Why Replace This Part
Most replacements are required after crash deployment. Other reasons include damaged or corroded connectors, wiring faults caused by repeated seat movement, or visible damage to the module or seat structure. Because this is a critical safety component, any signs of damage or prior deployment mean replacement is mandatory.
