Description
Passenger airbag deactivation switch for CITROËN and PEUGEOT vehicles. Tested and functional. Removed from a PEUGEOT 307.
This passenger airbag deactivation switch is an OEM-style replacement part intended for Citroën and Peugeot models. It allows the passenger airbag to be manually turned off when a rear-facing child seat is fitted or when specific safety conditions require airbag deactivation. The switch is a direct-fit unit removed from a Peugeot 307 and carries the common product references used when searching spare parts: 96392531XT and 8216K4. Ideal for professional mechanics and competent DIY technicians, this switch restores correct operation of the passenger airbag disable function and clears related cockpit control tasks when installed correctly.
Technical Information
- Manufacturer: Citroën / Peugeot (Stellantis)
- Model: Removed From Peugeot 307
- Product Codes: 96392531XT, 8216K4
- Additional Numbers: NFP
Function And Application
The switch provides a manual signal to the airbag control unit to disable the front passenger airbag. It is used whenever transporting small children in a rear‑facing child seat on the front passenger position (if allowed) or for service scenarios requiring the passenger airbag to be switched off. When the switch is set to OFF, the airbag control system must receive and register the deactivation signal and typically shows a dashboard indicator confirming the airbag is disabled.
Installation Recommendations
- Safety First: Disconnect the negative battery terminal and wait at least two minutes before working on the supplemental restraint system to reduce the risk of accidental deployment.
- Access: Remove the relevant trim or glovebox panel to reach the switch mounting location on the passenger side of the dash. Keep fasteners and clips organized.
- Electrical: Unplug the switch connector, compare pin layout, and install the replacement. Inspect wiring and connector for corrosion or damage and repair if necessary.
- Verification: Reconnect the battery, cycle the switch, and verify the passenger airbag indicator behavior. Use a diagnostic tool to read or clear any stored fault codes related to the airbag system if required.
- Final Check: Reassemble trim, ensure the switch sits flush and the bezel clips correctly, and confirm that the airbag warning light behaves normally during an ignition cycle.
Why This Part Typically Fails
Passenger airbag switches are generally long‑lived, but common failure causes include mechanical wear of the switching mechanism, damage to the key barrel or rocker, contact corrosion or contamination, moisture ingress behind the dash, and connector wiring faults caused by improper removal or repeated servicing. Physical impacts to the glovebox or dash area and electrical shorts may also render the switch inoperative. A faulty switch can result in the inability to disable the passenger airbag or can trigger airbag warning lights on the instrument cluster.
