U0105
System
Network (CAN Bus)
Wymagany skaner
Full-system scanner (engine, ABS, SRS, transmission, service resets)

Lost Communication with Fuel Injector Control Module

Understand U0105, common causes, and the right TOPDON scanner to diagnose it.

Fuel injector control module offline on some diesel or multi-ECU gasoline platforms.

Typowe objawy

  • No-start or limp mode
  • Multiple U-codes

Typowe przyczyny

  • Failed injector driver module
  • CAN wiring in engine bay
  • Low voltage
  • Blown fuse

Jakiego skanera potrzebujesz?

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

Użyj danych na żywo i freeze frame przed wymianą części. Kody ABS, SRS i U zwykle wymagają skanera full-system.

Wskazówki diagnostyczne

  • Zapisz freeze frame, gdy pojawi się kod
  • Kasuj kod dopiero po usunięciu przyczyny
  • Sprawdź powiązane kody pending
  • Sprawdź, czy napięcie akumulatora jest powyżej 12,4 V przed podejrzeniem czujników
