Technical Information
- Manufacturer: Stellantis (CITROËN / PEUGEOT)
- Model: Citroën C4 (5-Door, C4 I), Peugeot 307 (5-Door)
- Product Codes: 96527696XX, 8974T5
- Other Numbers: 8974.T5
Function And Characteristics
This assembly combines the seat belt webbing, retractor and a pyrotechnic pretensioner. In the event of a qualifying impact the pretensioner fires to remove slack from the belt instantly, securing the occupant more effectively and improving the performance of the airbag. Pretensioners are single-use safety devices: once activated they must be replaced.
Typical Causes Of Failure
Seat belts and pretensioners most commonly fail or require replacement for the following reasons:
- Deployment During A Crash: Activation of the pyrotechnic charge makes the unit unusable and requires replacement.
- Mechanical Wear And Tear: Frayed webbing, damaged buckles or worn retractors from long-term use or improper handling.
- Corrosion Or Connector Damage: Moisture and corrosion at the electrical connector can create SRS faults or prevent pretensioner activation.
- Electrical Faults: Open circuits, damaged wiring or poor contacts in the SRS loop can cause warning lights and disable the system.
Replacement Guide And Installation Recommendations
These instructions are intended as a general guide for trained technicians and competent DIYers. Always follow the vehicle manufacturer’s service manual for exact procedures and torque values.
- Disconnect The Negative Battery Terminal And Wait At Least 10 Minutes To Allow The SRS Capacitors To Discharge.
- Remove Interior Trim Panels And Seats As Required To Access The Retractor And Lower Anchor Points.
- Carefully Disconnect The Electrical Connector For The Pretensioner (Observe Connector Locking Mechanisms).
- Unbolt The Retractor And Any Mounting Brackets, Remove The Old Assembly.
- Install The New Seat Belt Assembly, Secure Bolts To The Manufacturer’s Specified Torque.
- Reconnect The Pretensioner Connector And Reinstall Trim Panels. Reconnect The Battery.
- Clear Any SRS Fault Codes Using A Diagnostic Tool And Verify The Airbag Light Is Off Before Returning The Vehicle To Service.
Important: Because the seat belt pretensioner is part of the Supplemental Restraint System, correct installation and diagnosis with an appropriate SRS-capable diagnostic tool is strongly recommended. If the airbag warning lamp remains on after replacement, further diagnosis of the SRS circuit is required.
Why Replace This Part
Beyond crash deployment, replacement is recommended when the belt webbing is torn or excessively worn, the retractor fails to retract smoothly, or the SRS system reports a pretensioner fault. Driving with a compromised seat belt assembly reduces occupant protection and may prevent the airbag system from operating as designed.
