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.

Veelvoorkomende symptomen

  • Airbag light on
  • Vehicle may have deployed bags visually

Typische oorzaken

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

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
