Function
The seat-mounted passenger airbag is part of the SRS restraint system. In the event of a significant frontal or offset impact, the module inflates within milliseconds to reduce forward movement of the passenger and lower the risk of head and chest injuries. The unit contains an inflator and a folded cushion integrated in the seat structure and connects to the vehicle SRS wiring harness.
When To Replace
Replace the airbag if it has deployed in a crash, if diagnostic trouble codes indicate an open/short or internal inflator fault, or if the airbag shows physical damage (rips, burns, contamination). There is no routine calendar interval for replacement; service is required after any event that triggers the airbag system or when SRS warning lamps remain on.
Installation Recommendations
- Disconnect the vehicle battery and wait at least 10 minutes before starting work to allow the SRS capacitors to discharge.
- Use appropriate tools and avoid power tools directly on airbag fasteners to prevent damage to the module or connectors.
- Carefully remove seat trim and access panels to reach the airbag module; unplug the SRS connector by releasing the locking tab—do not pull on wiring.
- Handle the airbag module with care: keep the deployment surface pointed away from you and place the module with the cushion facing upwards when set down.
- After fitting the new module, reconnect the battery and clear SRS codes with a diagnostic tool; verify the system’s status and confirm the airbag indicator extinguishes.
- Follow vehicle manufacturer procedures and torque settings for seat and airbag fasteners where specified.
Most Common Reasons For Failure
- Deployment In A Collision — The airbag is designed for one-time use and must be replaced after activation.
- Connector Or Wiring Damage — Corrosion, broken pins, or damaged seat harnesses can cause open/short faults and SRS warnings.
- Physical Damage During Repairs — Incorrect removal or impact to the seat structure can damage the inflator or cushion.
- Contamination Or Moisture — Water ingress into connectors or the seat base may lead to electrical faults.
