Reliable replacement passenger airbag switch for Citroën and Peugeot vehicles. This unit is commonly referenced under part numbers 96373645ZL and 8216F2 and is used to enable or disable the passenger airbag when fitting child seats or performing vehicle conversions. Designed for mechanics and experienced DIYers, the switch offers a straightforward swap to restore correct airbag status indication and safe operation of the restraint system.

The passenger airbag switch controls the On/Off state of the passenger-side airbag and communicates that status to the vehicle’s safety electronics. Symptoms of a faulty switch include a persistent airbag warning light, inability to change the airbag status, a loose or damaged key/rotor, or intermittent electrical contact. The part is often searched by its product code, so listing the OE numbers in the product title improves findability.

How It Is Replaced

• Locate The Switch: Typically installed on the passenger side of the dashboard or inside the glovebox area depending on model. Access usually requires removal of the lower dash trim or glovebox trim panel.
• Disconnect Power: Always disconnect the vehicle battery and wait to allow the airbag system to discharge before working on the system (see installation recommendations below).
• Remove Trim And Connector: Unscrew or unclip the trim, unplug the electrical connector, and remove the faulty switch from its mounting.
• Install New Switch: Fit the replacement switch, reconnect the connector, reassemble trim panels and reconnect the battery.
• Verify Operation: After installation, confirm that the airbag indicator and passenger airbag status behave correctly on ignition.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën Berlingo; Citroën C5; Citroën Xsara; Citroën Xsara Picasso; Peugeot Partner
• Product Codes: 96373645ZL, 8216F2
• Additional Numbers: 8216F2 | 96373645ZL

Installation Recommendations

• Disconnect The Battery: Always disconnect the negative battery terminal and wait at least 2 minutes before starting work to reduce the risk of accidental airbag deployment.
• Use Proper Tools: Use the correct trim tools and screwdrivers to avoid breaking panels or the switch housing.
• Handle Connectors Carefully: Do not force electrical plugs; inspect for corrosion or damaged pins and replace connectors if necessary.
• Post-Installation Check: Confirm that the airbag warning lamp behaves normally and that passenger airbag On/Off status is reported correctly by the vehicle.

Why The Part Most Often Fails

• Mechanical Wear: Repeated use and key rotation over many years can wear the internal mechanism causing looseness or failure to engage.
• Physical Damage: Impact or improper removal/install of trim panels can break the switch housing or key slot.
• Contamination And Corrosion: Moisture or dirt ingress can corrode contacts and lead to intermittent operation or electrical failure.
• Electrical Issues: Damaged wiring or connector faults in the dash loom can mimic switch failure and should be inspected.

Stellantis Citroën Peugeot part numbers 96373645ZD, 96373645ZL and reference 8216F2. This passenger airbag switch is an OEM-fit component designed for use in multiple Citroën and Peugeot vehicles. It provides a reliable method to enable or disable the front passenger airbag where required (for example when a child seat is installed) and is commonly searched by its product codes. Built for workshop use and DIY repairs, the switch offers a direct-fit replacement that restores correct passenger airbag control when the original switch has failed or been damaged.

Function And Benefits

The passenger airbag switch allows the vehicle to detect whether the passenger airbag should be active or locked out. Typical benefits include clear mechanical or key-operated control, straightforward diagnostics of lock state via the vehicle’s SRS system, and compatibility with original mounting points and electrical connectors on supported Citroën and Peugeot models.

Typical Fitment

• Citroën Berlingo
• Citroën C5
• Peugeot Partner

Replacement Procedure

• Safety First: Disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge before starting work.
• Accessing The Switch: Remove the trim panel or glovebox components necessary to reach the dashboard area where the passenger airbag switch is mounted. Exact trim removal depends on model and year.
• Disconnect: Unplug the electrical connector from the switch. Inspect the connector and wiring for corrosion or damage.
• Remove Switch: Unscrew or unclip the switch from its mounting. Keep any retainers for reuse if in good condition.
• Install New Switch: Fit the replacement switch into the original mounting, secure with screws or clips, reconnect the electrical connector and reassemble trim panels.
• Verification: Reconnect the battery and start the ignition. The SRS warning lamp should behave according to the vehicle’s manual (lamp goes out after self-test). If the SRS warning lamp remains on, perform a diagnostic readout and clear fault codes with suitable diagnostic equipment.

Installation Recommendations

Always observe SRS safety procedures. Disconnect the negative battery terminal and wait at least 10 minutes before beginning. Use trim tools to avoid damaging interior panels. Check connector pins for corrosion and secure wiring harnesses away from moving parts. If the airbag warning lamp does not extinguish after installation, read and clear SRS fault codes with a professional diagnostic tool. For complex SRS faults or after accident damage, have the system inspected by a qualified technician.

Why This Part Commonly Fails

Passenger airbag switches usually fail due to mechanical wear (key mechanism wear or broken internal detent), water ingress or connector corrosion, accidental impact or improper removal, and damage caused by collisions. Poor electrical contact or damaged wiring can also prevent correct communication with the safety restraint system, triggering warning lights and disabling proper operation.

Notes For Mechanics And DIYers

This switch is commonly sought by part number; keep the OE references handy when ordering. While replacement is straightforward for experienced technicians and competent DIYers, respect SRS precautions and verify system status with diagnostics after installation. Correct fitment and secure electrical connections are essential to restore reliable passenger airbag control.
