Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is turned off.
Gather tools and equipment for the job.

2. Use an OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s OBD-II port, typically located under the dashboard near the driver's seat.
Turn on the ignition without starting the engine to power the scanner.
Follow the scanner's prompts to read and clear the error codes.

3. Clear the Codes

Select the option to clear the codes on the scanner.
Confirm the action when prompted, allowing the scanner to erase the stored DTCs and turn off the check engine light.

4. Disconnect the Battery (if necessary)

If codes do not clear with the scanner, disconnect the negative battery terminal using a socket wrench.
Wait for approximately 10-15 minutes to allow the vehicle's computer to reset.
Reconnect the negative battery terminal securely.

5. Test Drive the Vehicle

Start the engine and take the vehicle for a test drive to ensure the check engine light does not re-illuminate.
