Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, wrench
  • Make sure the vehicle is parked on a flat surface, and the engine is off.
2. Scan for Error Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port located under the dashboard.
  • Turn the ignition to the "ON" position without starting the engine.
  • Follow the scanner's instructions to read and record any error codes.
3. Clear Error Codes
  • Use the OBD-II scanner's function to clear the stored error codes.
  • Confirm that the scanner indicates the codes have been successfully cleared.
4. Disconnect Battery
  • Using the socket set, loosen the negative battery terminal bolt and carefully remove the cable from the terminal.
  • Wait for at least 10 minutes to ensure any residual power is discharged.
5. Reconnect Battery
  • Reattach the negative battery cable and tighten the bolt securely.
  • Ensure there is no corrosion on the terminal. If corrosion is present, clean it before reconnecting.
