1. Preparation

Ensure the vehicle is parked on a flat surface.
Gather necessary tools and equipment.

2. Obtain an OBD-II Scanner

Connect the OBD-II scanner to the vehicle's OBD-II port, typically located under the dashboard near the driver's seat.
Turn the ignition to the "On" position without starting the engine.

3. Retrieving and Clearing Codes

Follow the scanner's instructions to read the stored trouble codes.
Once any issues are resolved, navigate to the "Clear Codes" or "Erase Codes" option on the scanner.
Confirm the action to reset the check engine light. The scanner should indicate that the codes have been cleared.
