Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather tools needed for the process.

2. Use OBD-II Scanner

Locate the OBD-II port under the dashboard on the driver's side.
Plug in the OBD-II scanner and turn the ignition to the "on" position without starting the engine.
Follow the scanner's prompts to read and record any stored error codes.

3. Clear Error Codes

With the engine still off, navigate to the "Erase Codes" or "Clear Codes" option on the scanner.
Confirm the action to clear the error codes from the vehicle’s computer.
Wait for the scanner to indicate that the codes have been successfully erased.

Disconnect the OBD-II scanner.
Start the engine and observe if the check engine light remains off.
Drive the vehicle for a short distance (10-15 minutes) to ensure the light does not return.
