Definition

The OBD2 code B1379 indicates a malfunction in the oil change reset button circuit, specifically a short to ground, which means there is an unintended connection to the vehicle's ground that is affecting the circuit's operation

Common causes

  • Damaged wiring or connectors
  • Shorted circuit
  • Faulty oil change reset button
  • Corroded terminals
  • Malfunctioning body control module (BCM)
  • Improper installation or modifications

Common misdiagnoses

  • Faulty oil change reset button
  • Wiring issues in the circuit
  • Malfunctioning engine control module (ECM)
  • Incorrect oil change interval settings
  • Faulty oil pressure sensor
  • Issues with the vehicle's body control module (BCM)
  • Problems with the instrument cluster
  • Software glitches in the vehicle's system

Troubleshooting steps

  1. 1. Check the Vehicle's Manual

    Refer to the vehicle's service manual for specific information about the oil change reset button circuit and its components

  2. 2. Visual Inspection

  3. 3. Inspect the wiring and connectors associated with the oil change reset button. Look for any signs of damage, fraying, or corrosion

  4. 4. Check for any loose or disconnected wires that may be causing a short to ground

  5. 5. Test the Reset Button

  6. 6. If accessible, test the oil change reset button itself for proper operation. You can use a multimeter to check for continuity when the button is pressed

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

  8. 8. Check for Shorts

  9. 9. Use a multimeter to check for continuity between the reset button circuit and ground. If you find continuity where there shouldn't be any, there may be a short in the wiring

  10. 10. Inspect the wiring harness for any pinched or damaged wires that could be causing a short to ground

  11. 11. Inspect Related Components

  12. 12. Check any related components, such as fuses or relays, that may be part of the oil change reset circuit. Replace any blown fuses or faulty relays

  13. 13. Scan for Additional Codes

  14. 14. Use an OBD-II scanner to check for any additional trouble codes that may provide more context for the issue. Address any other codes that may be present

  15. 15. Clear the Code

  16. 16. After performing the above checks and repairs, clear the trouble code using an OBD-II scanner and see if it returns after a test drive

  17. 17. Consult a Professional

  18. 18. If you are unable to identify or resolve the issue, it may be best to consult a professional mechanic or technician who has experience with your specific vehicle make and model. By following these steps, you should be able to diagnose and potentially resolve the issue related to the B1379 code. Always ensure safety precautions are taken when working on a vehicle's electrical system
