Function And Common Failure Modes
The passenger airbag is a primary restraint component that inflates in the event of a qualifying impact to reduce injury to the front-seat occupant. Airbags do not wear out on a fixed schedule but may require replacement after deployment, electrical faults, water ingress, or when SRS warning indicators show a persistent error. Physical damage from collisions or improper handling can render the module non-functional.
When To Replace
Replace the module after any deployment, when the SRS warning light remains on after diagnostic attempts, or if the airbag housing or connector is visibly damaged. Do not attempt to reuse a deployed module.
Installation Notes
Installation should follow vehicle manufacturer procedures and correct safety practices. General steps include:
- Disconnect the vehicle battery and wait at least 10 minutes to discharge the SRS capacitors.
- Remove the passenger-side trim or dashboard cover to access the airbag module.
- Unscrew the mounting fasteners, carefully disconnect the SRS connector, and remove the old module.
- Fit the replacement module, reconnect the electrical connector, secure mounting fasteners to the vehicle manufacturer's specification, and reassemble trim.
- Perform a full SRS system diagnostic and reset using a suitable scan tool to confirm correct operation.
Because the airbag system is a critical safety device, professional installation and post-installation diagnostic verification are recommended for less experienced installers.
