Solution

1. Preparation

Ensure the vehicle is parked on a flat surface, and the ignition is off.
Gather necessary tools, including an OBD-II scanner or a wrench (for battery disconnection).

2. Using an OBD-II Scanner

Locate the OBD-II port under the dashboard, near the driver's side.
Plug the OBD-II scanner into the port.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's instructions to read the codes.
Once noted, select the option to clear/reset the codes on the scanner.
Confirm the reset process; the check engine light should turn off.

3. Battery Disconnection Method (if no scanner is available)

Turn off the vehicle and remove the key from the ignition.
Open the hood and locate the battery.
Use a wrench to disconnect the negative (-) terminal first, followed by the positive (+) terminal.
Wait for at least 10 minutes to allow the system to reset.
Reconnect the positive (+) terminal first, then the negative (-) terminal.
Close the hood and start the vehicle to check if the check engine light is off.
