Definition

The OBD2 code B1711 indicates a malfunction in the driver front seat up switch circuit, specifically that there is a short circuit to the battery, causing the circuit to receive constant power

Common causes

  • Shorted wiring or connectors
  • Faulty seat switch
  • Damaged seat control module
  • Corroded or loose electrical connections
  • Malfunctioning power supply to the seat switch
  • Grounding issues in the circuit

Common misdiagnoses

  • Faulty seat switch
  • Wiring harness issues
  • Short circuit in the seat control module
  • Malfunctioning power seat motor
  • Issues with the body control module (BCM)
  • Battery or charging system problems
  • Grounding issues in the seat circuit

Troubleshooting steps

  1. 1.Verify the Code

    Use an OBD-II scanner to confirm the presence of the B1711 code. Clear the code and see if it returns after a short drive

  2. 2.Inspect the Wiring and Connectors

  3. 3.Check the wiring harness and connectors associated with the driver’s seat switch. Look for any signs of damage, fraying, or corrosion

  4. 4.Ensure that all connectors are securely attached and free of dirt or moisture

  5. 5.Check the Seat Switch

  6. 6.Test the driver’s seat switch for proper operation. You can do this by using a multimeter to check for continuity and resistance in the switch

  7. 7.If the switch is faulty, it may need to be replaced

  8. 8.Inspect the Seat Motor

  9. 9.Check the seat adjustment motor for any signs of malfunction. If the motor is shorted or drawing excessive current, it could cause the code to trigger

  10. 10.Test the motor by applying direct power to see if it operates correctly

  11. 11.Examine the Ground Connections

  12. 12.Ensure that the ground connections for the seat switch and motor are clean and secure. A poor ground can lead to erratic behavior and trigger fault codes

  13. 13.Check for Short Circuits

  14. 14.Use a multimeter to check for shorts in the wiring between the switch and the motor. Look for continuity where there shouldn’t be any

  15. 15.Inspect the wiring for any signs of wear or damage that could cause a short to battery

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

  17. 17.If all other components check out, the issue may lie within the BCM. Check for any software updates or known issues with the BCM related to seat controls

  18. 18.If necessary, perform a reset or reprogramming of the BCM

  19. 19.Consult Wiring Diagrams

  20. 20.Refer to the vehicle’s wiring diagrams to understand the circuit layout and identify any other components that may be involved in the circuit

  21. 21.Perform a Visual Inspection

  22. 22.Look for any aftermarket modifications or repairs that may have been done to the seat or electrical system that could affect the circuit

  23. 23.Test Drive

  24. 24.After making any repairs or adjustments, clear the code and take the vehicle for a test drive to see if the code returns. If you are unable to resolve the issue after these steps, it may be advisable to consult a professional mechanic or technician who has experience with automotive electrical systems
