Description
Passenger Airbag Switch – Passenger Side For Citroën And Peugeot Vehicles.
This passenger airbag switch is an original equipment style control used to enable or disable the front passenger airbag on selected Citroën and Peugeot models. Frequently searched by part numbers 96413912XT, 96413912ZD and 6556EJ, this switch is intended for professional workshops and DIY mechanics who perform safety-system repairs and replacements. The unit fits the passenger side installation points and restores the manual airbag on/off function when the factory switch is worn or damaged.
Technical Information
- Manufacturer: Stellantis
- Model: Passenger Airbag Switch (Passenger Side)
- Product Codes: 96413912XT, 96413912ZD, 6556EJ

Function And Purpose
The passenger airbag switch provides a manual way to deactivate the front passenger airbag when carrying a rear-facing child seat or when required by safety regulations. Mounted in the passenger side dash or glovebox area depending on the model, the switch completes or breaks the airbag enable circuit and signals the restraint control module of the selected state.
Compatibility And Fitment
Commonly compatible models include Citroën C3 Aircross, Citroën C3 III, Citroën C4 Picasso, Citroën C8, Peugeot 207, Peugeot 3008 I, Peugeot 308, Peugeot 5008 I and Peugeot 807. Always verify the correct part number for the vehicle—this switch is often located and ordered by its product code.
Replacement Procedure
Basic replacement steps for experienced technicians and competent DIYers:
- Disconnect the negative battery terminal and wait at least 10 minutes to reduce the risk of unintentional airbag deployment.
- Remove the relevant trim panel or glovebox door to access the switch mounting point using plastic trim tools to avoid damage.
- Unplug the electrical connector from the old switch, remove the retaining screws or clips, and extract the switch assembly.
- Install the new switch in reverse order: secure mounting, connect the wiring harness, re-fit trim, and reconnect the battery.
- After installation, cycle ignition and confirm the airbag warning lamp behavior: the lamp should perform its normal self-check sequence. If an airbag warning remains, further diagnostic with a suitable scan tool may be required.
Installation Recommendations
- Work In A Static-Free Environment And Use Insulated Tools When Working Near Airbag Components.
- Always Disconnect The Battery Before Starting Work And Observe The Recommended Waiting Time.
- Use Trim Removal Tools To Avoid Damaging Dash Panels And Fasteners.
- Inspect Connectors And Wiring For Corrosion Or Damage; Replace Damaged Plugs Or Clips Rather Than Reusing Them.
- Perform A Post-Install System Check: Verify The Airbag Indicator Behavior And Confirm Correct Switch Operation.
- If Uncertain, Refer Repairs To A Qualified Technician With Airbag System Experience.
Common Faults And Typical Causes
Passenger airbag switches commonly fail due to mechanical wear of the internal contacts, dirt and moisture ingress, connector corrosion, or impact damage from collisions. Symptoms of a failing switch include an illuminated airbag warning light, inability to change the switch position, loose or intermittent switch operation, or a permanently deactivated/activated passenger airbag state. Failures are more likely on older vehicles or where the switch is exposed to harsh conditions or repeated mechanical force.
Why The Part Fails Most Often
The most frequent causes are contact wear and contamination, physical damage to the switch mechanism, and connector corrosion. Repeated use, spills, or panel removal can accelerate wear. In many cases the visible switch assembly is damaged while the underlying wiring remains intact, making replacement of the switch the straightforward remedy.
Who Should Install
Installation Is Suitable For Professional Mechanics And Experienced DIYers Familiar With Vehicle Restraint Systems. Because The Airbag System Is A Safety-Critical Feature, Follow All Safety Precautions During Removal And Installation.
