Solution

1. Preparation

Gather tools: OBD-II scanner, battery terminal wrench (if necessary).
Ensure the vehicle is in a safe, well-ventilated area.

2. Connect the OBD-II Scanner

Locate the OBD-II port 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.

3. Reset the Check Engine Light

Follow the instructions on the OBD-II scanner to navigate to the "Erase Codes" or "Clear Codes" option.
Select this option to reset the check engine light.
Wait for the scanner to confirm that the codes have been erased.

4. Disconnect the Battery (Optional)

If the OBD-II scanner method does not work, disconnect the negative battery terminal using a battery terminal wrench.
Leave it disconnected for approximately 15 minutes to allow any residual power to drain from the system.
Reconnect the negative battery terminal securely.
