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.

Veelvoorkomende symptomen

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

Typische oorzaken

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

Welke scanner heb je nodig?

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

Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert
