Airbag Warning Lamp Circuit Failure

Understand B1616, common causes, and the right TOPDON scanner to diagnose it.

SRS module cannot verify airbag warning lamp operation — bulb or circuit fault.

Typowe objawy

  • No airbag light at key-on (illegal in many regions)
  • Stored B-code

Typowe przyczyny

  • Burned out airbag warning bulb
  • Cluster fault
  • Wiring to warning lamp

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
