Solution

1. Preparation

Gather necessary tools including an OBD-II scanner.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery if you prefer a manual reset method, allowing a few minutes before reconnecting.

2. Using an OBD-II Scanner

Locate the OBD-II port, typically found under the dashboard near the driver’s seat.
Plug the OBD-II scanner into the port.
Turn the ignition key to the "ON" position without starting the engine (or press the start button without pressing the brake pedal).
Follow the scanner's instructions to navigate to the "Read Codes" section and record any trouble codes.
Clear the codes by selecting the "Erase Codes" option on the scanner. Confirm the action when prompted.
Disconnect the OBD-II scanner from the port.

3. Manual Reset (Optional)

Disconnect the negative terminal of the battery using a socket wrench.
Wait for approximately 10-15 minutes to allow all systems to reset.
Reconnect the negative terminal and tighten securely.
Start the engine and check if the check engine light has turned off.
