  • Check engine light
  • Multiple U-codes

Cause tipiche

  • Failed glow plug module
  • CAN wiring
  • Blown fuse

Di quale scanner hai bisogno?

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

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

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