Function And Fitment
The passenger seat airbag is a seat-mounted supplemental restraint system component. It is engineered to deploy in appropriate impact conditions to limit passenger movement and reduce the forces acting on the chest and pelvis. Correct fitment is critical for proper deployment geometry and occupant protection.
How Replacement Is Performed
- Disconnect the negative battery terminal and wait at least 10 minutes to allow residual energy in the SRS system to dissipate.
- Remove seat trims and covers carefully to access the airbag module; avoid cutting or damaging upholstery and wiring harnesses.
- Unplug the airbag connector(s) and remove the retaining bolts securing the module to the seat frame.
- Install the replacement airbag, secure bolts to the manufacturer’s specification, reconnect the connector(s), and reassemble trims.
- After installation, verify SRS system status and clear any fault codes with a compatible diagnostic tool (DiagBox/Lexia/PP2000 or an equivalent capable of PSA protocols).
Installation Recommendations
Always follow manufacturer procedures and safety precautions when working with SRS components. Wear appropriate personal protective equipment, avoid static discharge near the airbag, and handle the module with the trim side facing away from you. Do not attempt repairs on an airbag module that has been deployed or visibly damaged. Use proper diagnostic equipment to confirm system integrity and to reset the airbag indicator after replacement.
Common Failure Causes
Seat airbags typically fail or require replacement for the following reasons:
- Deployment During A Collision — The most common cause; once deployed, the module must be replaced.
- Electrical Connector Damage Or Corrosion — Faulty contacts from moisture, spills, or poor handling during seat removal can cause SRS faults.
- Wiring Harness Damage — Chafing or previous repairs that compromised the wiring may interrupt the airbag circuit.
- Water Intrusion Or Seat Wetting — Long-term exposure to moisture can corrode connectors and inflator components.
- Tampering Or Improper Previous Repairs — Non‑OEM interventions can leave the system unreliable.
