Lost Communication with Restraints System Module

Understand U0170, common causes, and the right TOPDON scanner to diagnose it.

Airbag/SRS module not communicating — overlaps with U0151 on some vehicles.

Typowe objawy

  • Airbag light on
  • B-codes may accompany

Typowe przyczyny

  • Failed SDM/airbag module
  • CAN wiring
  • Low voltage
  • Prior deployment event

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
