Product Description And Function
The passenger seat airbag is an integral part of the Supplemental Restraint System (SRS). It is mounted inside the passenger seat and is deployed in the event of a qualifying collision to reduce the risk of injury to the front-seat passenger. The unit includes the airbag cushion and inflator/squib assembly appropriate for the listed models and connects to the vehicle’s SRS wiring harness and control module.
Compatibility And Fitment
This airbag is intended for Citroën C4 II (B7) and DS4 seats that accept the listed part numbers. Fitment is typically direct where the OEM connector and mounting points match the original. Because this part is often searched by its part number, verify the numbers stamped or printed on the old unit before ordering to ensure correct match.
Installation Recommendations
- Always disconnect the vehicle battery before beginning work on the SRS system and follow the manufacturer’s specified wait time to allow capacitors to discharge (commonly several minutes).
- Remove the seat from the vehicle if necessary to access the airbag module safely; work on a dry, static-free surface.
- Handle the airbag module with care—keep the trim side facing away from you and avoid impact or exposure to heat.
- Ensure all connectors are fully engaged and free of corrosion. Replace any damaged wiring or connectors before fitting the new module.
- After installation, use an appropriate diagnostic tool to clear SRS fault codes and confirm the system is functioning correctly; inspect that the SRS warning lamp extinguishes after the test sequence.
- If unsure, have the replacement carried out or checked by a qualified technician experienced with Citroën/Peugeot SRS procedures.
Why This Part Commonly Fails
- Deployment During A Collision: The most frequent reason for replacement is airbag deployment in an accident—deployed modules must be replaced.
- Wiring Or Connector Damage: Wear, corrosion, or mechanical damage to the seat wiring harness can interrupt the squib circuit and trigger SRS faults.
- Seat Occupancy Sensor Issues: Faults in the occupancy/weight sensor system within the seat can lead to incorrect SRS behavior, prompting replacement or further diagnosis.
- Water Ingress Or Corrosion: Moisture from spills or prolonged damp conditions can corrode connectors or internal components, causing failure.
- Improper Previous Repair: Incorrect handling, damaged connectors, or improper reinstallation after prior service can introduce faults.
Additional Notes For Mechanics And DIYers
This part is often listed and searched by its OEM number—keeping that number handy speeds up identification. Always follow Citroën/DS service procedures for SRS work. Replace any single-use items and ensure the integrity of the seat belt pretensioner system as part of SRS repairs.
