Description
Crash sensor – In the event of a collision activates safety systems (airbags and seatbelt pretensioners). Acceleration sensor ABL.
This impact sensor is designed for Citroën and Peugeot vehicles and is commonly identified by part numbers such as 9654903480, 96413912ZD and 8216PJ. The unit senses rapid deceleration and sends the signal to the restraint control system to deploy airbags and pretensioners when required. Ideal for professional workshops and experienced DIY mechanics who search by product code for fast identification and replacement.
Key Features
– Direct replacement for original equipment part numbers 9654903480 / 96413912ZD / 8216PJ.
– Function: Detects sudden deceleration (impact) and triggers airbag modules and seatbelt pretensioners.
– Sensor Type: Acceleration/Impact Sensor (ABL).
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C4 Picasso; Peugeot 207
- Product Codes: 9654903480, 96413912ZD, 8216PJ
- Additional Numbers: 96413912ZD, 8216PJ
Fitment And Replacement Procedure
Location and exact mounting vary by model. The crash/acceleration sensor is typically mounted centrally in the vehicle (for example under the center console or behind the dashboard) to reliably detect vehicle deceleration. Follow these general steps when replacing the sensor:
- Disconnect the vehicle battery and wait at least 2 minutes to avoid accidental deployment of restraints.
- Remove interior trim panels to access the sensor location (center console, under seats or behind dash depending on model).
- Unplug the electrical connector and remove the mounting fasteners.
- Install the new sensor in the same orientation and torque bolts to manufacturer specifications.
- Reconnect the connector and reassemble trim panels.
- Reconnect the battery and clear airbag fault codes using a diagnostic tool. Verify that the airbag warning lamp extinguishes and perform a system check.
Installation Recommendation
Work On Airbag Systems Should Be Performed By Trained Personnel Or Experienced Mechanics. Always Observe Safety Precautions: Disconnect The Battery Before Starting Work And Wait To Ensure Capacitors Are Discharged. Use Proper Tools And A Diagnostic Scanner To Clear Fault Codes And Confirm System Status After Installation.
Why The Part Fails
Crash sensors usually remain functional for the life of the vehicle unless affected by one of the following:
– Vehicle Impact: Sensors Are Often Damaged Or Triggered During A Collision.
– Corrosion Or Moisture Ingress: Electrical Connectors Exposed To Water Or Corrosion Can Cause Faults.
– Electrical Issues: Short Circuits, Wiring Damage Or Poor Grounding Can Lead To Malfunction.
– Mechanical Damage: Improper Handling During Repairs Can Affect The Sensor’s Calibration.
Practical Notes For Buyers
Search By Part Number (9654903480, 96413912ZD, 8216PJ) To Quickly Identify Compatibility With Your Vehicle. After Replacement, Use A Compatible Diagnostic Tool To Reset The Airbag System And Confirm Proper Operation. For Complex Cases, Professional Diagnostic Equipment Is Recommended.
