Solution

1. Preparation

Gather necessary tools: OBD-II scanner, notebook for recording codes, and any required replacement parts.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Connect OBD-II Scanner

Locate the OBD-II port, typically found under the dashboard near the driver's seat.
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 error codes.

3. Address Underlying Issues (if applicable)

If any error codes indicate a specific problem (e.g., faulty sensor, emissions issue), address those first by replacing or repairing the affected components.
Ensure the gas cap is secured and in good condition, replacing it if necessary.

4. Clear the Check Engine Light

With the OBD-II scanner still connected, navigate to the option for clearing codes.
Select “Erase Codes” or “Clear Codes” and confirm the action. This will turn off the check engine light.

5. Monitor Vehicle Performance

Disconnect the OBD-II scanner and start the vehicle.
Monitor the dashboard for any warning lights, ensuring the check engine light remains off.
