Lost Communication with ECM/PCM

Understand C0290, common causes, and the right TOPDON scanner to diagnose it.

ABS module cannot communicate with engine control module on the vehicle network.

Veelvoorkomende symptomen

  • Multiple warning lights
  • U0100 may accompany

Typische oorzaken

  • CAN bus fault
  • Low battery
  • Failed ECM or EBCM
  • Gateway issue

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
