Solution

1. Preparation

Gather necessary tools: OBD-II scanner, vehicle owner's manual.
Ensure the vehicle is parked on a level surface and in the 'OFF' position.

2. Scan for Codes

Connect the OBD-II scanner to the vehicle's OBD-II port, typically located under the dashboard.
Turn the ignition key to the 'ON' position (do not start the engine).
Follow the scanner's instructions to retrieve and record any diagnostic trouble codes.

3. Address Underlying Issues

If any DTCs are present, diagnose and repair the root cause of the check engine light.
Common issues may include replacing faulty sensors, fixing leaks, or addressing fuel system problems.

4. Clear the Codes

With the OBD-II scanner still connected, navigate to the option to clear or erase the codes.
Confirm the action as per the scanner's instructions.
Disconnect the OBD-II scanner from the port.

5. Verify Reset

Start the vehicle and monitor whether the check engine light remains off after a few moments.
Take the vehicle for a short drive to ensure that the light does not re-illuminate.
