Installation Recommendations

Follow safe workshop procedures when replacing an airbag control unit: always disconnect the vehicle battery and wait at least 10–15 minutes (or follow the manufacturer specified interval) before starting work to avoid accidental deployment. Remove interior trim panels to access the module, unplug electrical connectors carefully, and unbolt the unit from its mounting. After fitting the replacement unit, use a compatible diagnostic tool to read and clear SRS fault codes and to perform any required system checks. For PSA vehicles, professional DiagBox/Lexia equipment is recommended for full diagnostics and verification of system readiness. Handle the unit with care and avoid exposing connectors to moisture or contamination during installation.

Why This Part Fails Most Often

Common causes of airbag control unit failure include a previous collision (the unit records crash events and is often replaced after airbag deployment), water ingress or corrosion of connectors, electrical surges or short circuits, and internal component degradation over time. Faults may present as SRS warning lights on the dashboard, stored fault codes, or disabled airbag/pretensioner functions. Because the unit is central to occupant restraint deployment, any SRS warning should be diagnosed promptly and repaired by a qualified technician.

Practical Notes For Fitment

• Verify the product codes 1495658080 and 654674 against the vehicle’s SRS module label before installation.
• Replacement is generally necessary after airbag deployment or when the module reports unrecoverable SRS faults.
• After installation, perform a full SRS system scan and clear stored crash data if appropriate using a diagnostic interface.

Conclusion

This airbag control unit is a practical replacement option for Citroën C8 and Peugeot 807 owners and workshops seeking to restore SRS functionality. With correct installation and post-fit diagnostics, it returns critical safety systems to operational condition and helps ensure occupant protection.
