Deployment Commanded — Primary Crash Sensing

Understand B0052, common causes, and the right TOPDON scanner to diagnose it.

SRS module recorded a primary crash deployment event.

Sintomi comuni

  • Airbag light on
  • Deployed components visible

Cause tipiche

  • Prior accident with deployment
  • Module needs replacement
  • False trigger from sensor fault

Di quale scanner hai bisogno?

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

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

  • Registra il freeze frame quando compare il codice
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare i sensori
