Solution

1. Preparation

Gather necessary tools: OBD-II scanner, vehicle owner's manual.
Ensure the vehicle is parked on a flat surface with the ignition off.

2. Connect the OBD-II Scanner

Locate the OBD-II port, usually found under the dashboard near the driver's seat.
Plug the OBD-II scanner into the port and turn on the ignition without starting the engine.

3. Reset the Check Engine Light

Follow the prompts on the OBD-II scanner to navigate to the "Read Codes" or "DTC" section.
If there are any stored codes, choose the option to "Clear Codes" or "Erase Codes."
Confirm the action when prompted on the scanner.

4. Disconnect the Battery (Alternative Method)

If you do not have an OBD-II scanner, disconnect the negative terminal of the battery.
- Use a socket set to loosen the bolt on the negative terminal.
- Remove the terminal and wait for about 15 minutes.
- Reconnect the negative terminal and ensure it is tight.

5. Test the Vehicle

Turn the ignition on to check if the check engine light remains off.
Start the engine and verify that the light does not illuminate again.
