Driver Seat Track Position Sensor Circuit

Understand B1340, common causes, and the right TOPDON scanner to diagnose it.

Driver seat position sensor tells SRS how far seat is adjusted.

Vanliga symptom

  • Airbag warning
  • Deployment strategy compromised

Typiska orsaker

  • Failed track sensor
  • Wiring in seat rail
  • Seat disassembly damage

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
