Definition

The OBD2 code B1380 indicates a malfunction in the oil change reset button circuit, which may prevent the oil change reminder system from functioning properly

Common causes

  • Faulty oil change reset button
  • Damaged wiring or connectors
  • Short circuit in the circuit
  • Open circuit in the circuit
  • Malfunctioning engine control module (ECM)
  • Corroded terminals
  • Poor ground connection

Common misdiagnoses

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

Troubleshooting steps

  1. 1. Check the Owner's Manual

    Refer to the vehicle's owner manual for specific information regarding the oil change reset button and its location

  2. 2. Inspect the Button

    Physically inspect the oil change reset button for any visible damage or wear. Ensure that it is not stuck or jammed

  3. 3. Check Wiring and Connectors

    Examine the wiring and connectors associated with the oil change reset button. Look for frayed wires, corrosion, or loose connections that could cause a circuit failure

  4. 4. Test the Button

    Use a multimeter to test the continuity of the oil change reset button. If the button does not show continuity when pressed, it may need to be replaced

  5. 5. Scan for Additional Codes

    Use an OBD-II scanner to check for any additional trouble codes that may provide more context or indicate related issues

  6. 6. Inspect the Instrument Cluster

    In some vehicles, the oil change reset button may be integrated into the instrument cluster. Check for any issues with the cluster itself

  7. 7. Check for Software Updates

    Sometimes, a software glitch can cause issues. Check if there are any available updates for the vehicle's onboard computer system

  8. 8. Clear the Code

    After performing any repairs or adjustments, clear the trouble code using an OBD-II scanner and see if it returns after a test drive

  9. 9. Consult a Professional

    If the issue persists after performing the above steps, it may be best to consult a professional mechanic or technician who can perform more advanced diagnostics

  10. 10. Replace Components if Necessary

    If you identify a faulty button, wiring issue, or other component, replace it as needed. By following these steps, you should be able to diagnose and potentially resolve the B1380 code related to the oil change reset button circuit failure
