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.

Vanliga symptom

  • Airbag light on
  • Deployed components visible

Typiska orsaker

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

Vilken scanner behöver du?

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

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer
