Suitable for a variety of models from the PSA group, including Citroën C3 Aircross, Citroën C3 III, Citroën C4 Picasso, Citroën C8, Peugeot 207, Peugeot 3008 I, Peugeot 308, Peugeot 5008 I, and Peugeot 807, this switch is a versatile replacement part highly valued by both professional mechanics and do-it-yourself car enthusiasts.

The passenger airbag switch plays a vital role in vehicle safety by allowing the airbag to be deactivated when necessary, for example when a child seat is installed on the passenger seat. Over time, switches may fail due to wear or electrical faults, leading to potential safety issues or warning lights on the dashboard. Replacing the switch restores full functionality of the airbag system, ensuring the safety of all passengers.

Installation requires caution and should be performed by qualified personnel or experienced mechanics to maintain compliance with vehicle safety standards. Correct replacement guarantees that all airbags and related safety systems function properly, offering peace of mind during every drive.

Installation Recommendation

Before starting any work on the SRS system, disconnect the vehicle battery (negative terminal) and wait at least two minutes to allow residual charge to dissipate from the airbag capacitors. Locate the passenger airbag switch—on affected Citroën and Peugeot models it is typically found on the passenger side of the dashboard or inside the glovebox trim. Remove the necessary interior panels, unplug the switch connector and unfasten the retaining screws or clips. Fit the new switch, reconnect the connector, reassemble trim and reconnect the battery. Finally, verify correct function by checking that the passenger airbag indicator behaves normally (no persistent airbag warning light). If an airbag warning lamp remains lit, a diagnostic scan of the SRS system may be required.

Most Common Reasons For Failure

• Mechanical Wear: Frequent use and key operation can wear contacts and the locking mechanism over time.
• Contact Corrosion: Moisture ingress or long-term exposure to humidity can corrode electrical contacts and cause intermittent or permanent failure.
• Accidental Damage: Damage during interior repairs or removal/installation of trim pieces can break switch housings or connectors.
• Electrical Faults: Wiring damage or poor connector contact can lead to false airbag fault codes or loss of switch function.
• Aging Plastics: Sunlight and heat can degrade plastic components, making the switch harder to operate or causing the key slot to fail.

This replacement is intended for mechanics and experienced DIYers who follow safety procedures for SRS systems. Using the correct part code when ordering ensures compatibility and simplifies installation in Citroën and Peugeot vehicles listed above.

This genuine-style crash/impact sensor is designed for Citroën and Peugeot vehicles and is commonly referenced by part numbers 9654903480, 96413912ZD and 8216PJ. It senses sudden deceleration and provides the trigger signal for the airbag control system and seatbelt pretensioners, helping to ensure rapid deployment of safety devices in an impact. Ideal for professional workshops and experienced DIY mechanics who search by product code when sourcing replacement parts.

Application And Compatibility

Fits selected models from Citroën and Peugeot, commonly used on Citroën C4 Picasso and Peugeot 207. Always confirm the part number against your vehicle documentation or existing part marking. This sensor is typically listed under electrical components → sensors for Stellantis vehicles.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot compatible)
• Model: Citroën C4 Picasso; Peugeot 207
• Product Codes: 9654903480; 8216PJ
• Additional Numbers: 96413912ZD

Function And Typical Location

The sensor measures rapid deceleration (impact) and sends a signal to the airbag control unit to deploy airbags and activate pyrotechnic seatbelt pretensioners. Depending on vehicle layout and model variant, the sensor may be mounted on the vehicle structure in the front crash zone or inside the passenger compartment on structural members. Exact mounting location varies by model—refer to the vehicle repair manual for the precise position.

Installation Recommendations

• Disconnect the battery before starting work and follow the vehicle manufacturer’s safety procedures.
• Locate the sensor using the vehicle service manual or the original part location, unplug the electrical connector and carefully unbolt the sensor from its mounting bracket.
• Install the replacement sensor in the same orientation as the original; incorrect orientation can prevent proper operation.
• Tighten fasteners to the manufacturer’s specified torque values and ensure connectors are clean and secure.
• After installation, perform a full diagnostic scan and clear any fault codes. Verify that the airbag warning lamp behaves normally; if the lamp remains on, consult a diagnostic tool for fault details.

Most Common Failure Reasons

• Direct damage in a previous collision—sensors are often replaced after impact because they are designed to detect and react to crashes.
• Moisture ingress or corrosion at the connector, causing intermittent or permanent electrical faults.
• Connector damage or wiring faults caused by improper repairs or vehicle modifications.
• Internal electronic failure due to age, vibration or manufacturing defects.

Replacement of the crash sensor is a safety-critical repair. If in doubt, have the job performed or checked by a qualified technician and use appropriate diagnostic equipment to confirm correct operation of the restraint system after fitting.
