Installed inside the seat structure, it works together with the vehicle’s airbag control unit and seat belt system to protect the occupant’s torso and pelvis during an impact.
How To Replace
- Safety First: Disconnect the negative battery terminal and wait at least 10 minutes to allow the airbag system capacitors to discharge.
- Remove Seat Trim: Carefully remove the seat upholstery and trim panels to access the airbag module. Keep fasteners and clips organized.
- Disconnect Connector: Unplug the airbag connector from the control harness. Inspect the connector for corrosion or damage.
- Unbolt Airbag Module: Remove the retaining bolts and lift out the old airbag module.
- Install New Module: Fit the replacement airbag, secure bolts to the manufacturer’s specification, reconnect the harness, and reinstall trim.
- Final Check: Reconnect the battery, perform a full system diagnostic and clear any fault codes with a diagnostic tool. Confirm airbag lamp extinguishes and no persistent faults remain.
Installation Recommendations
- Always disconnect the battery and wait the recommended interval before working on the airbag system.
- Handle the airbag module with care: store with the deployment face upwards and avoid impact, heat, and static discharge.
- Use OEM-quality fasteners and avoid reusing damaged clips or connectors.
- After installation, verify system integrity with an appropriate diagnostic tool and clear/confirm any stored fault codes.
- If unsure, have the replacement carried out or checked by an experienced technician.
Common Failure Reasons
- Previous Deployment: Airbags that have deployed in a collision must be replaced.
- Connector Or Wiring Damage: Corrosion, cut wires, or damaged connectors can interrupt the circuit and trigger faults.
