Impact Sensor Circuit Malfunction

Understand B0102, common causes, and the right TOPDON scanner to diagnose it.

Front or side impact sensor circuit fault — second impact sensor ID on some networks.

Typowe objawy

  • Airbag light on
  • Sensor may need replacement after crash

Typowe przyczyny

  • Failed impact sensor
  • Wiring after front-end repair
  • Sensor mounting loose

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
