Quale scanner ti serve?

Enhanced OBD2 scanner (live data graphs, freeze frame, battery voltage test)

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono spesso uno scanner mult sistema.

Consigli diagnostici

  • Registra il freeze frame quando il codice compare la prima volta
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla i codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare un sensore
