Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert
