AFIL sensor 3 Citroën Peugeot 9653381180 6590W1

Description

Lane driving sensor AFIL number 3 for CITROEN PEUGEOT
cars
The screw that holds the unit to the undercarriage may be broken – must be unscrewed

Part description

This AFIL Sensor (Lane Keeping Sensor) No. 3 is an electrical component used in Citroën/Peugeot cars for the Lane Keeping Assist function. If you are dealing with malfunctioning lane monitoring or system outages, sensor replacement is one of the typical diagnostic and repair steps.

The part is intended as a used car part – an ideal choice for a quick and reasonably priced repair. During assembly, take into account that there may be a notched mounting screw (according to the note on the part), which may require drilling.

Installation recommendations

Note: The documents do not contain a detailed assembly procedure for a specific model. So below is the general/typical procedure for replacing an electrical sensor of this type; the exact steps may vary depending on the car design and approach to the part.

1) Before assembly (checks of used part)

• Compare the part numbers on the label/case: 9653381180 and 6590W1, or another designation 603.013.
• Check the condition of the connector (bent pins, oxidation), cable entry and sensor body (cracks, deformation).
• Check that the mounting points are correct and that there are no fasteners missing.
• Be aware that the clamping screw may be notched – be prepared to drill it out.

2) Necessary tools and materials (in general)

• Basic set of ratchets/bits and screwdrivers
• Tool for disassembling plastic covers/clips
• Cleaning agent for electrical contacts + cloth
• In case of a problem with the screw: a tool for loosening stiff joints, or equipment for drilling (drills, hole punch)
• Protective gloves and goggles

3) Step-by-step assembly procedure (typically)

1. Park the car on level ground, secure it against movement and turn off the ignition.
2. Disconnect the battery (recommended safety procedure for electrical parts).
3. Ensure access to the sensor by removing the necessary covers/panelling (according to the specific car design).
4. Locate the sensor and carefully disconnect the electrical connector (unlock the connector first).
5. Check the condition of the connector and, if necessary, gently clean it with a contact cleaner.
6. Release the sensor attachment. If the screw is damaged/cracked, proceed with caution: first try loosening with a suitable tool; if this does not help, boring may be necessary (work precisely to avoid damage to surrounding parts).
7. Disassemble the original sensor and compare it with the replacement piece (shape, connector, mounts).
8. Place the replacement sensor in the correct position and fix it.
9. Connect the electrical connector and check that it is fully seated and secured with a fuse.
10. Reinstall all the removed covers/trims and check that nothing is rubbing and that the wiring is securely attached.
11. Connect the battery.
12. Check the function of the system (depending on the car’s equipment) and monitor whether error messages appear.

• 4) Post-assembly checks and test drive/function verification

  • Check that the connector holds, the cable is not stretched and is not routed in a place where it could rub.
  • Check that after installation there is nothing in the way/in the way and that the covers are properly seated.
  • If it is possible for your car, verify the AFIL function during normal operation under conditions where the system is activated by default (depending on the equipment and settings of the car).

  5) The most common assembly mistakes + how to avoid them

  • Damage to the connector or fuse when disconnecting – release the fuse in the correct direction and without prying with force.
  • Incorrect positioning of the sensor – before tightening, align the position according to the handles so that the sensor does not “sit crooked”.
  • Underestimation of a notched screw – if drilling is necessary, work accurately and protect surrounding parts; it pays to use a hole punch and proceed step by step.
  • Not disconnecting the battery – can lead to an unwanted short circuit or electrical errors; for electric sensors, disconnecting the battery is a safe standard.

  Reasons why the part is damaged

  • Vibration and mechanical stress at the attachment point (loose attachment, long-term operation).
  • Moisture, oxidation and contamination in the connector or on the contacts.
  • Damage to the wiring (abrasion, pinching, bad routing of the bundle).
  • Unprofessional disassembly/assembly – torn or chipped screws, cracked handles, damaged connector pins.
