System
Supplemental Restraint (Airbag)
Wymagany skaner
Full-system scanner (engine, ABS, SRS, transmission, service resets)

Deployment Commanded — Deployment Loop Activation

Understand B0051, common causes, and the right TOPDON scanner to diagnose it.

SRS module recorded a deployment event or loop activation — often after accident or module fault.

Typowe objawy

  • Airbag light on
  • Vehicle may have deployed bags visually

Typowe przyczyny

  • Prior accident deployment
  • Module needs replacement after event
  • Incorrect repair procedure

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
