1) Before assembly

• Check that all numbers on the original and replacement part match.
• Compare the shape of the unit, the mounting, the connectors and the overall condition of the contacts.
• Inspect the used part for cracks, signs of overheating, oxidation or mechanical damage.
• Before starting work, disconnect the battery according to the normal principles of safe work on vehicle wiring.

2) Necessary tools and materials

• Basic set of hand tools
• Suitable bits and sockets
• Plastic pry bar to remove covers if needed
• Electrical contact cleaner
• Clean lint-free cloth
• Protective gloves

3) Step-by-step assembly procedure

1. Switch off the ignition and secure the vehicle against unwanted movement.
2. Disconnect the battery and wait until the vehicle’s electrical systems have completely calmed down.
3. Access the original drive by removing covers or associated parts if they prevent access.
4. Check carefully the wiring and the condition of the connectors before disconnecting the original part.
5. Disconnect the electrical connectors without using excessive force to avoid damaging the latches.
6. Unfasten the original unit and carefully remove the part.
7. Compare the old and new part side by side, especially the numbers, mounting and connector part.
8. If necessary, gently clean the connectors and mating surfaces with a suitable agent for electrical contacts.
9. Place the replacement unit in place and fix it in the same way as the original part.
10. Connect the connectors so that they are properly secured and without tension in the wiring.
11. Reinstall all covers and removed parts.
12. Connect the battery and perform a basic system function check.
• 4) Post-assembly checks and test drive/function verification
  • Check for loose connectors or unsecured covers after assembly.
  • Verify that there are no unusual electrical system symptoms when the ignition is turned on.
  • Follow system behavior and function stability after startup.

  • Connector damage when disconnecting – never use brute force, release the connector lock first.
  • Assembly of a part with corroded contacts – before installation, check and clean the contact surfaces if necessary.
  • Insufficient fastening of the unit – after assembly, verify that the part holds firmly and does not transmit vibrations.
  • Working on the wiring with the battery connected – always follow a safe procedure for disconnecting the power supply before disassembly and assembly.

  Reasons why the part is damaged

  • Long-term thermal stress in the engine compartment or near other heated parts.
  • Voltage fluctuations in the vehicle’s electrical system.
  • Moisture, oxidation of contacts and penetration of dirt into connectors.
  • Mechanical damage during disassembly or improper handling.
  • Loose mounting, vibrations and subsequent stress on electronics and connections.
  • Wear caused by long-term operation of the START-STOP system.
