Rear Wheel Speed Sensor Correlation

Understand C0070, common causes, and the right TOPDON scanner to diagnose it.

ABS module detected mismatched rear wheel speed readings — one rear sensor may read differently from the other.

Typowe objawy

  • ABS light
  • Traction control activation on straight road
  • False stability intervention

Typowe przyczyny

  • One rear sensor failing
  • Different tire sizes on rear axle
  • Tone ring damage one side
  • Rear bearing play

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
