High-quality replacement right front pyrotechnic seat belt (seat belt pretensioner) designed for Toyota Aygo passenger side (5-door) vehicles manufactured up to 2013. This unit restores the critical restraint function after removal of a deployed or damaged belt assembly and is an OEM-compatible solution commonly sought under part numbers and codes listed below. Ideal for professional workshops and experienced DIY mechanics who require a direct-fit, safety-critical component.

Key Features And Function

The pyrotechnic seat belt pretensioner is an integral part of the Supplemental Restraint System (SRS). In the event of a collision, a small pyrotechnic charge activates the pretensioner, pulling the belt webbing tight in milliseconds to reduce occupant forward movement and improve airbag effectiveness. Outside of deployment, the retractor and locking mechanisms ensure smooth belt extraction and secure locking under sudden deceleration.

Compatibility And Application

Fits: Toyota Aygo (Passenger Seat, 5-door) – up to 2013. Also commonly compatible with equivalent models from the sister platforms: Citroën C1 and Peugeot 107 (corresponding years/variants). Check the part numbers below to confirm application for a specific vehicle variant.

Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Toyota Aygo (Passenger Seat), 5-Door, Up To 2013
• Product Codes: 7P1170-P
• Additional Numbers: 16084057XZ, B0009075XZ

Installation Recommendations

Always follow manufacturer procedures when replacing SRS components. General recommended steps for experienced technicians:

• Disconnect the vehicle battery and wait several minutes to allow the SRS capacitors to discharge before beginning work.
• Remove interior trim panels carefully to access the belt retractor and anchor points. Use appropriate trim tools to avoid damage.
• Unbolt the retractor and lower anchor using the correct sized sockets; keep fasteners and torque specifications according to the vehicle manual.
• Disconnect the electrical connector for the pretensioner. Inspect mating connectors and wiring for corrosion or damage and replace if necessary.
• Install the replacement unit, ensuring correct routing of the belt and secure engagement of the electrical connector. Tighten bolts to the manufacturer’s torque specification.
• After installation, verify proper belt operation (free travel, locking under sudden pull). Reset or diagnose SRS fault codes with appropriate diagnostic equipment if required.

Why The Part Fails Most Often

• Deployment During A Collision: The pyrotechnic pretensioner is single-use and must be replaced after activation in an accident.
• Corrosion Or Electrical Faults: Moisture, corrosion, or damaged wiring/connectors can render the pretensioner inoperative or create SRS faults.
• Mechanical Wear Or Webbing Damage: Cuts, fraying, or contamination of the belt webbing and retractor wear can degrade performance and necessitate replacement.
• Previous Improper Repairs: Incorrect installation or reuse of a deployed unit can cause malfunction.

Notes For Professionals

This is a safety-critical component. Replace only with the correct part number and follow the vehicle manufacturer’s service manual. After replacement, diagnosis with compatible SRS-capable diagnostic tools is recommended to clear any fault codes and confirm system readiness.

Installation Recommendations

Safety first: this unit contains a pyrotechnic pretensioner connected to the vehicle SRS. Before starting work always disconnect the battery and wait at least 10 minutes to allow SRS capacitors to discharge. Remove interior trim panels carefully to access the B‑pillar and lower anchorage points. Unbolt the retractor and electrical connector, replace with the new unit ensuring the belt webbing is routed correctly and not twisted, then secure all fasteners to the manufacturer’s torque specifications. After installation, check the belt for smooth payout/retraction and perform an SRS systems check—clearing or diagnosing fault codes may require a compatible diagnostic tool. Follow manufacturer procedures for safe handling and disposal of any deployed components.

How It Is Replaced (Overview)

• Disconnect negative battery terminal and wait at least 10 minutes.
• Remove trim panels to expose seat belt retractor and pretensioner mounting points.
• Disconnect electrical connector and unbolt the retractor and anchor bolts.
• Fit the replacement unit, route webbing correctly, and tighten bolts to factory torque.
• Reconnect the electrical connector, reassemble trim, and verify belt operation.
• Scan SRS system with a suitable diagnostic tool and clear any related fault codes if applicable.

Why This Part Commonly Fails

• Deployment In A Collision: Pyrotechnic pretensioners are single-use devices and must be replaced after deployment.
• Electrical Or Connector Faults: Corrosion, damaged wiring, or poor connections can render the pretensioner inoperative and trigger SRS faults.
• Age And Environmental Exposure: Long-term exposure to moisture or contaminants can compromise connectors and mounting hardware.
• Previous Repairs Or Incorrect Installation: Improper removal or incorrect routing/torquing can damage the mechanism or webbing.
