Full-system scanner (engine, ABS, SRS, transmission, service resets)

Nutzen Sie Live-Daten und Freeze Frame, bevor Sie Teile tauschen. ABS-, SRS- und U-Codes erfordern meist einen Vollsystem-Scanner.

Diagnose-Tipps

  • Freeze Frame erfassen, wenn der Code erstmals gesetzt wird
  • Code erst nach Behebung der Ursache löschen
  • Auf verwandte pending codes prüfen
  • Batteriespannung über 12,4 V prüfen, bevor Sie Sensoren verdächtigen
