Passenger Seat Belt For Citroën C4 First Series Three-Door Model
Pyrotechnic Seat Belt Pretensioner
Front Passenger Side
Product Overview
This pyrotechnic front passenger seat belt pretensioner is a direct-fit used replacement for Citroën C4 first‑generation three‑door models. Supplied under reference numbers 96479909XX, 8974KT (NFP), the unit is intended for professional garages and experienced DIY mechanics who require a reliable safety component after a collision or as part of belt system repair.
Function And Benefits
The pretensioner is a pyrotechnic device integrated with the seat belt retractor. In the event of a moderate to severe impact it activates to remove slack from the belt instantly, improving occupant restraint and reducing forward movement. Replacing a deployed or faulty pretensioner restores the seat belt’s full protective function and clears related SRS fault codes when properly diagnosed and reset.
How It Is Replaced
- Disconnect Battery: Always disconnect the vehicle battery and wait a sufficient time (manufacturer recommends waiting to allow the SRS capacitors to discharge) before starting work.
- Access: Remove interior trim panels around the B‑pillar and seat base to access the retractor and lower anchor bolts.
- Electrical Connector: Unplug the pretensioner electrical connector carefully and inspect for corrosion or damage.
- Mechanical Removal: Unbolt the retractor and anchor points, remove the old pretensioner module and fit the replacement.
- Reinstallation: Use correct fasteners and torque values as specified in the vehicle repair manual; replace mounting bolts if required by the manufacturer.
- Diagnostics: After installation, use an SRS diagnostic tool to check system integrity and to clear any related fault codes.
