Installation recommendations

Generally/typically for this type of part, the exact replacement procedure may vary depending on the specific model and make of the car. It is important to proceed carefully with the electronic control unit of the parking assistant in order not to damage the connectors, wiring or the module itself.

1) Before assembly

• Check that all product numbers on the old and new part match.
• Compare the type of connectors, their number and the overall design of the unit.
• Inspect the used part for cracks in the packaging, damaged pins, signs of moisture or corrosion.
• Check the condition of the wiring harness and connectors in the vehicle.
• Before starting work, disconnect the battery according to normal service practice.

2) Necessary tools and materials

• Basic set of hand tools
• Tools for removing covers and linings
• Flashlight
• Cleaning agent for electrical contacts suitable for automotive use
• Protective gloves

3) Step-by-step assembly procedure

1. Turn off the ignition and secure the vehicle against movement.
2. Disconnect the battery.
3. Access the storage location of the original unit by removing any necessary covers or trim.
4. Visually check the surroundings of the unit for signs of moisture, oxidation or mechanical damage.
5. Carefully disconnect the electrical connectors from the old unit. Do not pull on the cables, but only on the body of the connector.
6. Remove the original unit from the bracket or mount.
7. Compare the old and new part by numbers, connectors and body shape of the unit.
8. If the connectors are dirty, gently clean them with a suitable contact cleaner and allow to dry.
9. Mount the replacement unit in its original location and seat it properly.
10. Connect all connectors so that they are fully secured and without strain on the wiring.
11. Reinstall all removed covers and trim.
12. Connect the battery and perform a basic function check of the parking system.
• 4) Post-assembly checks and test drive/function verification
  • Verify that there are no parking assist error states when the system is turned on.
  • Test the system function in a safe area while maneuvering.
  • Check that the system responds smoothly and without dropouts.
  • If the vehicle reports a fault after the replacement, recheck the connectors, wiring condition and match the part number.

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

  • Part exchange by similar number – always compare all numbers on the label.
  • Connector damage during disassembly – use proper release procedure and do not pull on cables.
  • Installation in a dirty or damp area – before installation, check and, if necessary, clean the surroundings.
  • Insufficient connector seating – check that the connector is fully engaged after plugging in.
  • Omission to check the cabling – the fault does not always have to be only in the unit itself, but also in the subsequent electrical installation.

  Reasons why the part is damaged

  • Intrusion of moisture into the space of the unit or connectors
  • Corrosion of contacts and oxidation of electrical connections
  • Surge or voltage fluctuations in the vehicle’s on-board network
  • Mechanical damage during unprofessional disassembly or assembly
  • Damage caused by faulty wiring or poor contact in connectors
  • Long-term traffic load and natural wear and tear of electronics
