Function And Application
The roof-mounted side (curtain) airbag deploys from the headliner area above the doors to provide a cushioning barrier for the head and upper torso during lateral impacts or vehicle rollovers. It is fitted along the A- and B-pillar roof rail on the Driver Side of Peugeot 407 models. This part is a critical element of the Supplemental Restraint System (SRS) and must be handled and installed following safety procedures.
How Replacement Is Performed
Replacement requires careful work on interior trim and the vehicle’s SRS electrical system. Typical steps followed by professional mechanics or competent DIYers are:
- Disconnect the negative battery terminal and wait the manufacturer-recommended time to allow the SRS capacitors to discharge.
- Remove headliner trim, pillar covers, and any clips securing the curtain airbag module.
- Unbolt the airbag module and carefully disconnect the SRS connector(s).
- Install the replacement module, ensuring the harness and connectors are free of damage and fully engaged.
- Reinstall trim panels, reconnect the battery, and clear or verify SRS fault codes with an appropriate diagnostic tool.
Installation Recommendations
- Follow Peugeot repair manual procedures and torque specifications where applicable.
- Always disconnect the battery before starting work and observe anti-static precautions to avoid accidental deployment.
- Inspect wiring harnesses, connectors, and mounting points for corrosion or damage and repair before fitting the new unit.
- Verify correct orientation (Driver Side) and secure all fasteners. Use a diagnostic scanner to confirm SRS system status after installation.
- If Not Confident In SRS Work, Have A Qualified Technician Perform The Replacement.
