Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the driver’s side dashboard).
Turn on the ignition without starting the engine (position II).
Select the option to read error codes on the scanner.
Note any codes displayed for future reference.

3. Clear Error Codes

Navigate to the "Erase Codes" function on the OBD-II scanner.
Confirm the action to clear the codes.
Wait for the scanner to indicate that the codes have been successfully erased.

4. Disconnect Battery (Optional)

Turn off the ignition and disconnect the negative terminal of the battery using a socket wrench.
Wait 5-10 minutes to ensure that all systems reset.
Reconnect the negative terminal and ensure it is tight.

Start the engine and monitor the dashboard for the check engine light.
Ensure that the vehicle operates normally and listen for any irregular sounds.
