Solution

1. Preparation

Gather tools: OBD-II scanner, vehicle key, and possibly a battery terminal tool.
Ensure the vehicle is parked on a flat surface with the engine off.

2. Connect OBD-II Scanner

Plug the OBD-II scanner into the vehicle's OBD-II port, usually located under the dashboard near the steering column.
Turn the vehicle’s ignition to the "ON" position without starting the engine.

3. Access Error Codes

Follow the on-screen instructions on the OBD-II scanner to read and clear error codes.
If no codes are found, proceed to reset the light.

4. Reset Check Engine Light

Use the scanner's "Erase Codes" or "Clear Codes" function.
Confirm the action when prompted by the scanner.

5. Disconnect the Battery (optional)

If the scanner does not reset the light, disconnect the negative battery terminal for about 10-15 minutes to reset the ECU.
Reconnect the battery terminal securely.
