B1713 Seat Driver Front Down Switch Circuit Failure

The OBD2 code B1713 indicates a malfunction in the driver front seat down switch circuit, which may involve a failure in the switch itself, wiring, or the seat control module

Definition

The OBD2 code B1713 indicates a malfunction in the driver front seat down switch circuit, which may involve a failure in the switch itself, wiring, or the seat control module

Common causes

  • Faulty driver front seat down switch
  • Damaged wiring or connectors in the seat switch circuit
  • Short circuit in the seat down switch circuit
  • Open circuit in the seat down switch circuit
  • Malfunctioning seat control module
  • Corrosion or poor connections in the wiring harness
  • Faulty power supply to the seat switch
  • Issues with the vehicle's body control module (BCM)

Common misdiagnoses

  • Faulty seat motor
  • Wiring issues or shorts
  • Malfunctioning seat control module
  • Faulty body control module
  • Incorrectly installed or damaged seat assembly
  • Issues with the power supply to the seat
  • Problems with other seat switch circuits

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other related trouble codes. This can provide more context and help identify if there are multiple issues

  2. 2. Inspect the Seat Switch

  3. 3. Remove the seat switch from the driver's seat

  4. 4. Check for any visible damage, corrosion, or loose connections

  5. 5. Test the switch with a multimeter to ensure it is functioning correctly. You should see continuity when the switch is activated

  6. 6. Examine Wiring and Connectors

  7. 7. Inspect the wiring harness and connectors leading to the seat switch and the seat motor for any signs of damage, fraying, or corrosion

  8. 8. Look for any pinched or broken wires that could interrupt the circuit

  9. 9. Test the Seat Motor

  10. 10. If the switch appears to be functioning correctly, test the seat motor itself

  11. 11. Apply direct power to the motor to see if it operates. If it does not, the motor may be faulty and need replacement

  12. 12. Check for Ground Issues

  13. 13. Ensure that the ground connections for the seat motor and switch are secure and free of corrosion. A poor ground can cause circuit failures

  14. 14. Inspect the Body Control Module (BCM)

  15. 15. The BCM controls various electrical functions in the vehicle, including the power seat. If all other components check out, the BCM may be malfunctioning

  16. 16. Check for any software updates or recalls related to the BCM

  17. 17. Look for Short Circuits

  18. 18. Use a multimeter to check for short circuits in the wiring. A short can cause the circuit to fail and trigger the B1713 code

  19. 19. Clear the Code and Test Drive

  20. 20. After performing the above checks and repairs, clear the trouble code using the OBD-II scanner

  21. 21. Take the vehicle for a test drive to see if the code reappears

  22. 22. Consult a Professional

  23. 23. If the issue persists after performing these steps, it may be best to consult a professional mechanic or an automotive electrician for further diagnosis. By following these steps, you should be able to identify and resolve the issue related to the B1713 code
