Solution

1. Preparation

Gather necessary tools: OBD-II scanner, owner's manual.
Ensure the vehicle is off and in park mode.
Disconnect the battery for a few minutes to clear the system if preferred, but this may reset other systems as well.

2. Use an OBD-II Scanner

Connect the OBD-II Scanner: Locate the OBD-II port under the dashboard near the driver's seat and plug in the scanner.
Turn on the Ignition: Switch on the vehicle's ignition without starting the engine.
Access the Scanner Menu: Follow the prompts on the scanner to read and clear the error codes.
Clear the Codes: Select the option to clear or reset the codes related to the check engine light.
Remove the Scanner: Once completed, unplug the scanner from the OBD-II port.

3. Reconnect the Battery (if applicable)

Reconnect the Battery: If you disconnected the battery previously, reconnect the positive terminal first and then the negative terminal.
Tighten the Connections: Ensure the battery terminals are secured tightly to prevent any electrical issues.

4. Verify Reset

Start the Engine: Turn on the vehicle and observe if the check engine light remains off.
Monitor the Vehicle: Drive the vehicle for a short distance to confirm that the light does not reappear.
