Lost Communication with Restraints Control Module (Airbag)

Understand U0151, common causes, and the right TOPDON scanner to diagnose it.

Airbag module offline — SRS light on, airbags may not deploy in a crash until repaired.

Typowe objawy

  • Airbag light on
  • Horn or cruise inop (clock spring)

Typowe przyczyny

  • SRS module fault
  • Clock spring
  • Impact sensor wiring
  • Aftermarket seat swap without resistor

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
