Key Features & Function
The unit includes a pyrotechnic pretensioner integrated with the retractor. In a crash event the pretensioner fires to remove slack from the belt instantly, improving occupant restraint and reducing forward movement. The retractor mechanism locks the belt during sudden deceleration to secure the occupant. The assembly is a safety-critical component and must be installed correctly to ensure full functionality.
Installation Recommendations
- Before beginning work, disconnect the vehicle battery and follow the vehicle manufacturer’s safety procedures to prevent accidental deployment of pyrotechnic devices and damage to vehicle electrics.
- Remove interior trim panels to access the B‑pillar assembly and lower anchorage points. Keep fasteners and trim organized for reassembly.
- Carefully disconnect any electrical connector for the pretensioner; inspect harness and connector for corrosion or damage.
- Unbolt the old belt (retractor and lower anchor) and replace with the new unit. Ensure correct routing of the webbing and that the retractor is mounted in the original orientation.
- Tighten all mounting bolts to the vehicle manufacturer’s torque specifications. Do not overtighten or reuse damaged fasteners.
- After installation, check belt travel and locking operation by performing slow pulls and quick pulls on the webbing. Verify there are no obstructions and trim fits correctly.
- Any replacement involving pretensioners or airbag system components should be carried out by qualified personnel if you are not experienced with SRS systems.
Most Common Cause Of Failure
- Deployment After Collision: Pyrotechnic pretensioners are single-use. After deployment the entire assembly must be replaced.
- Mechanical Wear And Damage: Frayed or cut webbing, foreign object damage, or bent retractor components reduce effectiveness and may prevent proper locking.
- Corrosion And Contamination: Moisture or corrosion in connectors or mounting points can cause electrical failures or hinder retractor movement.
- Connector Or Wiring Faults: Damaged wiring or poor connections to the pretensioner can render the unit inoperative or generate fault codes in the restraint system.
Search and order using the listed product codes (e.g., 7P2170-P, 16084059XZ) to find the correct left front driver seatbelt for Toyota Aygo and its platform equivalents. Replace any deployed or visibly damaged belt immediately to maintain occupant safety.
