Wymagany skaner
Full-system scanner (engine, ABS, SRS, transmission, service resets)

Occupant Classification System Not Calibrated

Understand B1650, common causes, and the right TOPDON scanner to diagnose it.

OCS requires zero-point calibration after seat service or module replacement.

Typowe objawy

  • Passenger airbag always off
  • Airbag light on

Typowe przyczyny

  • Seat swap without calibration
  • New occupancy sensor not programmed
  • Battery disconnect sequence skipped

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
