Description
Overview
This Passenger Airbag Switch is designed for Citroën and Peugeot vehicles and is commonly identified by part numbers 96386084XT, 96386084ZL, 8216F3 and 8216E6. Targeted at professional auto technicians and experienced DIYers, the switch controls the enable/disable function of the front passenger airbag and is especially suitable for Citroën C3 Picasso and Peugeot 406, while potentially fitting other PSA models with the same part codes.
Function And Importance
The passenger airbag switch allows you to deactivate the passenger airbag when carrying a child seat in the front or when otherwise required for safety. Correct operation is essential: the switch communicates with the airbag control unit to ensure the passenger airbag is enabled or disabled according to the switch position, helping to protect occupants in a crash scenario.
Common Faults And Typical Causes
Failures usually result from mechanical wear, internal contact corrosion, moisture ingress, broken switch tumbler or connector issues. Symptoms include incorrect airbag indicator behavior on the dash, inability to switch airbag state, or stored fault codes in the airbag control module. Lifespan depends on use and environment; inspect the switch during trim or airbag system work.
Installation Guidance
Installation should be performed by a trained technician or an experienced DIYer following safety precautions. Typical replacement steps:
- Disconnect the negative battery terminal and wait at least 2 minutes to prevent accidental airbag deployment.
- Locate the passenger airbag switch (commonly on the passenger-side dashboard, in the glovebox area or related trim depending on the model).
- Remove the trim panel to access the switch, unplug the electrical connector and remove the retaining hardware.
- Fit the new switch, reconnect the plug and refit trim. Reconnect the battery and verify correct indicator behavior.
- Scan the airbag system for fault codes and clear them if necessary; if faults persist, consult an airbag specialist.
Condition And Inspection
This unit is used but has passed strict inspections to ensure it remains in very good condition and is fully functional. As a safety-critical component, visual inspection of the connector, mounting and switch mechanism is recommended before installation.
