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.

Veelvoorkomende symptomen

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

Typische oorzaken

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

Welke scanner heb je nodig?

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

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
