The right-hand pyrotechnic seatbelt pretensioner is an original-style safety component designed for Citroën C2, C3, C3 Pluriel and compatible Peugeot 1007 models. It quickly retracts slack from the seatbelt during a collision by means of a pyrotechnic charge, reducing occupant movement and improving the effectiveness of the restraint system. This unit is commonly sought under part numbers 9640676777, 8973TG and 8973TJ.

Key Benefits

Designed for professional fitment and reliable crash performance, this pretensioner restores factory-level occupant protection after deployment or removal of a faulty module. Clear OEM coding makes it easy to find the correct replacement by product number, saving workshop time and reducing vehicle downtime.

Function

The pretensioner contains a pyrotechnic actuator that, upon receiving a signal from the airbag control unit during a crash event, instantaneously reels-in the seatbelt webbing. This reduces the forward motion of the occupant and works together with the airbag to lower injury risk. It is a single-event safety device — if it has fired in an accident it must be replaced.

Installation Recommendations

• Work should be performed by a trained technician or an experienced DIYer familiar with SRS systems.
• Disconnect the negative battery terminal and wait at least 10 minutes before starting work to ensure SRS capacitors are discharged.
• Follow the vehicle manufacturer’s service manual for removal and refit procedures, connector release, and bolt torque values.
• Inspect surrounding wiring, seatbelt stalk, and connector for corrosion or damage and replace any compromised parts.
• After installation, clear SRS fault codes with an appropriate diagnostic tool and verify that the airbag/SRS warning light extinguishes during self-check.

Most Common Reasons For Failure

Pretensioners rarely fail under normal conditions but are rendered unusable if deployed in a collision. Other common causes of faults include electrical connector corrosion, water ingress, damage from previous repairs or improper handling, and shorts or open circuits in the seatbelt wiring. An illuminated SRS warning lamp or stored diagnostic fault codes related to the belt pretensioner indicate the unit needs attention.

Practical Tips For Mechanics And DIYers

• Always handle pyrotechnic safety devices with care — avoid impact, heat, and static risks.
• Keep the replacement part in its packaging until ready to fit and store in a dry environment.
• If the vehicle has been involved in an accident, inspect all restraint components (airbags, buckle switches, load limiters) and replace any parts showing signs of activation or damage.
• Using the referenced product codes during parts lookup speeds identification and reduces the chance of ordering an incorrect pretensioner.

This pretensioner is suitable for professional workshops and competent DIY installers who follow standard SRS safety precautions and manufacturer repair procedures.

Ideal for both professional mechanics and DIY car owners, this replacement part precisely fits the specified Citroën models to restore the vehicle’s original safety function. The installation process involves removing the seat trim and unfastening the old pyropretensioner unit before securing the new one in place, ensuring a secure and proper fit for optimal performance.

Pyropretensioners can degrade or become faulty over time due to exposure to various driving conditions or previous accident deployment. Regular inspection and timely replacement are essential to maintain the seatbelt system’s reliability. Failure to replace a malfunctioning pyropretensioner can compromise vehicle safety and passenger protection.
