Lost Communication with Steering Angle Sensor Module

Understand U0126, common causes, and the right TOPDON scanner to diagnose it.

Steering angle sensor module offline — ESC and EPS may be disabled until calibrated.

Typowe objawy

  • ESC light on
  • Heavy steering feel (EPS)
  • Stability control disabled

Typowe przyczyny

  • Clock spring failure
  • SAS module fault
  • Battery disconnect without recalibration

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
