Lost Communication with Power Steering Control Module

Understand U0220, common causes, and the right TOPDON scanner to diagnose it.

Power steering control module communication loss — distinct ID from U0131 on some networks.

Typowe objawy

  • Heavy steering
  • PS warning lamp

Typowe przyczyny

  • EPS module fault
  • CAN wiring to rack
  • Steering 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
