Description
Overview
This passenger pyrotechnic seat belt is a direct replacement for Citroën C4 3-door models (first generation). The unit includes a pyrotechnic pretensioner that rapidly tightens the belt during a collision to reduce occupant movement and improve the effectiveness of the airbag system. Supplied with the original part references 96479909XX and 8974KT.
Key Features
- Direct-fit replacement for Citroën C4 3-door (C4 I).
- Pyrotechnic pretensioner for immediate belt tightening in the event of impact.
- OEM-compatible mounting points and electrical connector for the SRS system.
- Designed for the passenger seating position to ensure occupant protection.
When And Why It Fails
Pretensioner units are designed to activate during a collision and must be replaced after deployment. Other causes of failure include electrical faults, corrosion at mounting or anchor points, water ingress, or severe mechanical wear. If the SRS warning light is illuminated after an incident, the seat belt pretensioner should be inspected immediately.
Replacement Guide
Replacement should be carried out by a qualified technician or an experienced DIY mechanic who understands airbag systems. Typical replacement steps:
- Disconnect the negative battery terminal and wait at least 10 minutes to ensure the SRS system is de-energized.
- Remove interior trim panels to access the belt retractor, anchor bolts and the pretensioner connector.
- Unplug the pretensioner electrical connector and unbolt the belt assembly from the vehicle structure.
- Fit the new unit, tighten bolts to the manufacturer’s torque specifications, reconnect the electrical connector and refit trim panels.
- Use appropriate diagnostic equipment to clear any SRS fault codes and confirm the airbag indicator is off before returning the vehicle to service.
Exercise caution when handling pyrotechnic components. If you are unsure about any step, consult a professional to avoid injury or incorrect installation.
