Function And Compatibility
The steering wheel airbag is part of the vehicle’s Supplemental Restraint System (SRS). It inflates in moderate to severe frontal impacts to reduce risk of head and chest injury. The module connects through the clock spring (spiral cable) to the airbag control unit and vehicle wiring harness. Compatible primarily with Peugeot 307 first-generation models; always check product codes against your vehicle’s original part number when searching.
Typical Faults And Why They Occur
Airbag modules usually fail or require replacement for the following reasons:
- Previous Deployment: Airbags that have deployed must be replaced.
- Electrical Faults: Damaged wiring, corroded connectors, or a faulty clock spring can cause circuit interruptions and airbag warning lights.
- Connector Damage During Repair: Improper removal or forcing connectors can damage contacts.
- Water Ingress Or Corrosion: Exposure to moisture can degrade electrical contacts and connectors.
Replacement Interval
There is no routine replacement interval for airbags. Replace the steering wheel airbag after deployment or when the vehicle diagnostic system indicates an airbag circuit fault that cannot be resolved by repairing wiring or connectors.
Installation Recommendations
Follow these safety-focused steps when replacing the steering wheel airbag. If you are not experienced with SRS systems, have the work performed by a qualified technician.
- Disconnect the Negative Battery Terminal And Wait: Always disconnect the negative battery cable and wait at least 10 minutes to ensure the SRS capacitors discharge before beginning work.
- Steering Wheel Position: Center the steering wheel (wheels straight ahead) and mark the wheel-to-column alignment to preserve airbag and steering alignment.
- Remove Airbag Module Carefully: Release retaining fasteners or clips on the rear of the steering wheel, then gently pull the airbag module forward. Do not pry on the pad or use excessive force.
- Disconnect Connectors Safely: Depress any locking tabs and separate airbag and horn connectors. Avoid pulling on wires; handle connectors only by the housing.
- Inspect Clock Spring And Connectors: Check the spiral cable for wear or damage and confirm correct alignment before reassembly. Replace the clock spring if damaged or if it causes a persistent fault code.
- Refit And Torque: Reinstall the new airbag module in the original orientation, secure fasteners to the manufacturer’s specified torque, and reconnect the battery last.
- Post-Installation Check: Clear SRS fault codes with appropriate diagnostic equipment and verify that the airbag warning lamp extinguishes and does not return.
- Safety Precautions: Avoid exposing the airbag to impact or heat. Do not use electrical test equipment across airbag squibs. Store and handle the module with the trim surface facing upward.
Why Professionals Prefer OE Codes
Airbag modules are frequently searched by OE part numbers. The provided product codes (96556746ZR, 4112HW) help workshops and technicians confirm compatibility quickly and reduce the risk of ordering an incorrect module.
Notes For Buyers
This listing is intended for professional mechanics and experienced DIYers who understand SRS safety procedures. Replacement of SRS components affects vehicle safety—if in doubt, have installation performed by a qualified service center.
