Deployment Commanded — Secondary Crash Sensing

Understand B0053, common causes, and the right TOPDON scanner to diagnose it.

Secondary crash sensing deployment event stored.

Veelvoorkomende symptomen

  • SRS lamp
  • Multiple B-codes

Typische oorzaken

  • Secondary impact sensor triggered
  • Module fault
  • Unrepaired prior collision

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
