Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to reset the ECU if necessary (optional).

2. Use an 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.
Follow the scanner's prompts to read and clear error codes.

3. Clear the Codes

Select the option on the scanner to "Erase Codes" or "Clear Codes."
Confirm the action when prompted by the scanner.
Wait for the scanner to confirm that the codes have been successfully erased.

4. Reconnect the Battery (if applicable)

If you disconnected the battery, reconnect the negative terminal first, then the positive terminal.
Ensure the connections are tight and secure.

5. Final Check

Start the engine and allow it to idle for a few minutes.
Observe the dashboard for the check engine light. It should remain off if the issue was resolved.
