Solution

1. Preparation

Ensure the vehicle is parked on a level surface with the engine off.

2. Connect OBD-II Scanner

Locate the OBD-II port, usually under the dashboard near the driver's seat.
Plug in the OBD-II scanner and turn the ignition to the "ON" position without starting the engine.

Follow the scanner instructions to read the trouble codes.
Document any codes for future reference.
Select the option on the scanner to clear the codes.
Wait for the scanner to confirm that the codes have been successfully cleared.

4. Battery Disconnect Method (Optional)

If the light remains on, use a socket set to disconnect the negative terminal of the battery.
Leave the terminal disconnected for at least 5 minutes to allow the ECM to reset.
Reconnect the negative terminal securely and ensure a solid connection.

Start the engine and observe the dashboard for the check engine light.
If the light is off, proceed to take a test drive to ensure no issues arise.
