Solution

1. Preparation

Gather necessary tools: OBD-II scanner, socket set, and safety gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Use an OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard on the driver's side.
Turn on the ignition to the "On" position without starting the engine.
Follow the scanner's prompts to read and clear any stored error codes.

3. Disconnect the Battery (Optional)

If the check engine light remains after clearing codes, use a socket set to disconnect the negative terminal of the battery.
Leave it disconnected for about 15 minutes to allow the vehicle's computer to reset.

4. Reconnect the Battery

Reconnect the negative battery terminal and ensure it is tightened securely.
Start the engine and check if the check engine light is still illuminated.
