Description
Safety pyrotechnic seat belt for Citroën C4 Picasso or C4 Grand Picasso. Left front seat – Driver.
Description
High-quality pyrotechnic seat belt pretensioner designed for the left front (driver) seat of Citroën C4 Picasso and C4 Grand Picasso models. The pretensioner is a safety-critical component that instantly tightens the lap and shoulder belt during a collision to reduce occupant movement and improve airbag effectiveness. Commonly searched by OE numbers, this part is compatible with vehicles that use the original Stellantis/Citroën assemblies (see Technical Information below).
Technical Information
- Manufacturer: Stellantis / Citroën
- Model: Citroën C4 Picasso, Citroën C4 Grand Picasso
- Product Codes: 9657326377, 8974XZ
- Other Numbers: None known
Compatibility And Use
Intended for left front (driver) installation. Check vehicle build and parts list against the OE numbers above when selecting the replacement. The pretensioner is a single-use pyrotechnic device: once deployed in a crash it must be replaced rather than repaired.
Installation Recommendations
Installation of a pyrotechnic seat belt pretensioner is a safety-critical task. Recommended procedure:
- Disconnect the vehicle battery and follow the manufacturer’s prescribed safety procedure to prevent accidental deployment.
- Remove interior trim as required to access the belt retractor and mounting points.
- Unplug electrical connectors carefully; inspect for corrosion or damage and replace connectors if necessary.
- Remove mounting bolts, replace the pretensioner with the correct orientation, and tighten bolts to the manufacturer’s torque specifications.
- Clear any SRS faults and verify system status with an appropriate diagnostic tool after reconnection.
Why The Part Most Commonly Fails
Pyrotechnic pretensioners most often become defective because they deploy during a collision (deployment is irreversible). Other causes include electrical faults, connector corrosion, water ingress, previous improper repairs, or mechanical damage to the retractor assembly. Age and long-term exposure to moisture or contaminants can also degrade connectors or mechanism reliability.
Practical Notes For Mechanics And DIYers
This part is intended for professional fitment but can be replaced by experienced DIYers who follow safety procedures and have access to proper tools. Never attempt to disassemble or modify the pyrotechnic element. After replacement, verify the airbag/SRS indicator and run a diagnostic check; unresolved faults can indicate wiring or sensor issues that must be addressed before the vehicle is returned to service.
Safety Reminder
Seat belt pretensioners are integral to occupant protection. Incorrect installation or reuse of a deployed pretensioner can result in loss of protection or unintended deployment. Always follow Citroën repair procedures and safety guidelines when handling or replacing this component.
