Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and safety gloves.
Ensure the vehicle is in a safe location with the engine off.

2. Use an OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard near the steering column.
Turn the ignition key to the "ON" position (do not start the engine).
Follow the scanner's instructions to read and clear trouble codes.

3. Address Underlying Issues

If any trouble codes are present, research and address the problems indicated before resetting the check engine light to avoid future issues.

4. Disconnect Battery

Using a socket set, locate the negative terminal of the battery (marked with a minus sign).
Carefully disconnect the negative terminal using the socket set and allow the vehicle's electrical system to drain by pressing the horn or turning on the headlights for 10 seconds.
Wait for approximately 5-10 minutes to ensure the ECU resets completely.

5. Reconnect Battery

Reconnect the negative terminal of the battery and tighten it securely with the socket set.
Start the vehicle and check if the check engine light remains off.
