Description
Steering Wheel Airbag for Peugeot 307
High-quality replacement steering wheel airbag designed for Peugeot 307 vehicles. This airbag restores frontal supplemental restraint system (SRS) functionality after deployment or when the original unit develops an electrical fault. Ideal for professional workshops and competent DIY mechanics who search by part number (96345026ZR, 4112HW). The compact design and OE-compatible connectors ensure correct fitment in the steering wheel hub and reliable integration with the vehicle SRS circuitry.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 307 (First Generation)
- Product Codes: 96345026ZR, 4112HW
- Other Numbers: NFP
Compatibility
Intended for use in Peugeot 307 first generation models. Always verify the part codes shown in the vehicle or on the original airbag to confirm compatibility.
Function
The steering wheel airbag is a core component of the frontal SRS, designed to inflate rapidly in the event of a qualifying collision to reduce the risk of head and chest injuries. The unit contains the module, inflator, and connector interfaces that communicate with the vehicle crash sensors and SRS control unit.
Replacement Procedure
Typical removal and installation steps for experienced technicians or competent DIYers:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow the SRS capacitors to discharge.
- Remove the steering wheel trim or horn pad fasteners following the vehicle manufacturer procedure.
- Carefully release and disconnect the airbag electrical connectors—avoid pulling on wiring.
- Remove the airbag module from the steering wheel and replace with the new unit, aligning connectors and mounting points precisely.
- Reconnect the airbag connectors, refit the trim, and reconnect the battery.
- Use a diagnostic tool to read and clear SRS fault codes and confirm proper system status. If the SRS warning lamp remains on, further diagnosis is required (clock spring, wiring, or control unit).
Installation Recommendations
- Always disconnect the battery before starting work and observe a minimum waiting period (10 minutes) to reduce the risk of accidental deployment.
- Handle the airbag module with the trim face pointing upward and store it face up during any temporary placement.
- Do not use excessive force on connectors or pins; inspect connectors for corrosion or damage and replace if necessary.
- Follow the vehicle manufacturer’s torque and assembly procedures for steering wheel fasteners.
- Verify SRS operation with a suitable diagnostic tool after installation.
Most Common Failure Causes
Steering wheel airbags typically fail or trigger an SRS fault due to:
- Clock Spring (Spiral Cable) Wear Or Breakage Causing Open Or Short Circuits In The Airbag Circuit.
- Corroded Or Damaged Connectors And Wiring In The Steering Column Area.
- Previous Deployment Which Renders The Module Non‑Functional.
- Impact Or Mechanical Damage To The Module Assembly.
This airbag unit is intended as a direct replacement part. For safe and reliable results, installation should be carried out by a trained technician or an experienced DIYer familiar with SRS systems and the required safety precautions.
