Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C5 II
- Product Codes: 96498320YW, 6554JH
- Additional Numbers: NFP
Function And Application
The AFIL switch controls the Lane Departure Warning (LDW) system, allowing the driver to activate or deactivate the function from the cabin. When the switch is operated, it sends the appropriate signal to the vehicle body control module or the assistance ECU, and the system status is indicated on the instrument cluster. Proper operation of this switch is essential for enabling lane monitoring and related alerts.
Compatibility And Identification
This switch is intended for Citroën C5 II vehicles and is commonly identified by the manufacturers’ product codes listed above. Many technicians and owners search by these part numbers when sourcing a replacement, so include them in parts lists and order confirmations for fast matching.
Installation Recommendations
- Disconnect Negative Battery Terminal Before Work: Always isolate the vehicle electrical system to prevent short circuits and unintended ECU events.
- Panel Removal: Carefully pry out the trim bezel around the switch using plastic trim tools to avoid damaging surrounding panels.
- Release And Unplug: Depress the retaining clips, pull the switch from the mounting socket and unplug the electrical connector.
- Fitment: Insert the replacement switch until clips engage, reconnect the wiring connector and reassemble the trim bezel.
- System Check: After installation, reconnect the battery and verify switch operation by enabling/disabling the AFIL function; confirm the instrument-cluster indication and, where available, check for fault codes with a diagnostic tool.
Why This Part Most Commonly Fails
- Electrical Contact Wear: Frequent use can wear internal contacts or cause intermittent connection.
- Corrosion And Moisture Ingress: Exposure to humidity or liquid spills can corrode terminals and cause failure.
- Mechanical Damage: Broken mounting tabs or damaged actuator from improper removal or impact.
- Connector Problems: Bent pins, loose wiring, or poor connector seating can mimic switch failure.
Symptoms And Diagnostic Tips
Common symptoms of a defective AFIL switch include the inability to toggle lane departure monitoring, no indicator change on the instrument cluster when operating the switch, or intermittent system faults appearing as warning messages. For diagnosis, inspect the connector for corrosion or loose pins, confirm power and ground at the switch harness, and scan the vehicle for related fault codes to distinguish between a switch fault and a control module or sensor issue.
This description is tailored for mechanics and experienced DIYers who value clear part identification and practical replacement guidance. Use the product codes 96498320YW and 6554JH when searching or ordering to ensure correct fitment for Citroën C5 II applications.
