Understand B1450, common causes, and the right TOPDON scanner to diagnose it.

High resistance in driver airbag deployment loop — clock spring common culprit.

Vanliga symptom

  • Airbag warning
  • Horn or cruise inop

  • Connector corrosion under steering wheel
  • Airbag module internal 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
