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.

Veelvoorkomende symptomen

  • Airbag warning
  • Deployment strategy compromised

Typische oorzaken

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

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
