Solution

1. Preparation

Tools Required: OBD-II scanner, socket set (if disconnecting the battery), safety gloves.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s data link connector, usually located under the dashboard near the steering column.
Turn the ignition to the "ON" position without starting the engine (or start the engine, depending on the scanner’s requirements).
Navigate the scanner menu to read and clear any stored trouble codes.
Select the option to clear the codes; confirm the action when prompted.

3. Disconnect Battery (if needed)

If the check engine light remains illuminated after using the OBD-II scanner, use a socket set to loosen and remove the negative battery terminal (black cable).
Leave the battery disconnected for 10-15 minutes to reset the vehicle’s computer.

4. Reconnect Battery

After the waiting period, reconnect the negative battery terminal and ensure it is tightened securely.
Start the engine and check that the check engine light is off.

5. Test Drive

Drive the vehicle for a short distance to allow the vehicle's onboard diagnostics to recheck systems.
Monitor the dashboard for the check engine light; if it does not illuminate, the reset was successful.
