Dashboard airbag, passenger airbag for Peugeot 407
This passenger airbag module is designed for the dashboard of Peugeot 407 models. It protects the front-seat passenger by deploying in a collision to reduce the risk of head and chest injuries. The unit is commonly referenced by its part numbers and is a standard replacement part for Peugeot 407 vehicles with factory-installed passenger airbag systems.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 407
- Product Codes: 9644588880, 8216CK
- Other Numbers: NFP
Suitable Models
Fits Peugeot 407 series, including Saloon (Sedan), Estate (SW) and Coupé body styles where the factory passenger airbag configuration is original.
Function And Purpose
The passenger airbag is an integral part of the Supplemental Restraint System (SRS). In the event of a qualifying frontal impact, the airbag control unit triggers the inflator, deploying the airbag to cushion and distribute crash forces away from the passenger. It works together with seat belts and, where fitted, occupancy detection to provide optimal protection.
Replacement Procedure (Overview)
- Safety First: Disconnect the negative battery terminal and wait at least 10 minutes to ensure the SRS capacitors discharge.
- Access: Remove the glovebox or dashboard trim panels as required to reach the passenger airbag module fastenings.
- Unbolt: Unscrew the retaining bolts securing the module. Keep fasteners organized for reassembly.
- Disconnect: Carefully disconnect the airbag electrical connector(s). Avoid pulling on wiring; use the connector locking tab.
- Handle With Care: Place the removed module face up on a stable surface away from heat sources and static-sensitive areas.
- Installation: Refit the replacement unit in reverse order, ensuring connectors lock and mounting bolts are tightened to manufacturer torque specifications. Reconnect the battery and verify SRS indicator behavior with a diagnostic tool.
Installation Recommendations
Always follow vehicle manufacturer service procedures. Use appropriate personal protective equipment and a diagnostic scanner to confirm SRS system status before and after replacement. Do not use excessive force or metal tools near the inflator; avoid dropping or striking the module. Replace any single-use mounting hardware if specified by the manufacturer. After installation, clear faults and confirm the SRS warning lamp goes out during the ignition self-check.
Common Failure Causes
Passenger airbags can fail or require replacement for several reasons:
- Previous Deployment: Airbags that have deployed in a collision must be replaced.
- Electrical Faults: Corroded connectors, damaged wiring harnesses or poor grounding can produce SRS fault codes and disable the airbag.
- Water Ingress: Moisture or flooding can corrode connectors and electronics, causing malfunction.
- Control Unit Errors: Faults in the airbag control module or sensors can prevent proper deployment.
- Age And Environmental Factors: Long-term exposure to humidity, temperature cycles and contamination can degrade connectors and components.
