Solution
1. Preparation
  • Gather tools and materials: OBD-II scanner, multimeter, socket set, and replacement parts if necessary.
  • Disconnect the vehicle's 12V battery to ensure safety while working on the airbag system.
2. Inspect and Repair Wiring
  • Remove the driver's seat from the vehicle using a socket set (usually 13mm bolts).
  • Disconnect the wiring harness from the seat, locating the seat occupancy sensor connector.
  • Use a multimeter to check for continuity in the sensor's wiring. Repair or replace any damaged wires.
3. Replace the Seat Occupancy Sensor
  • If the sensor is faulty, remove the seat cover to access the sensor.
  • Disconnect the old seat occupancy sensor and replace it with a new one.
  • Reassemble the seat cover and reinstall the seat back into the vehicle.
4. Clear Error Codes
  • Reconnect the battery and use the OBD-II scanner to clear the B0001 code from the system.
  • Start the vehicle and check if the airbag warning light remains off.
