Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, and possibly a multimeter.
Ensure the engine is off and the keys are removed from the ignition.

2. Use an OBD-II Scanner

Locate the OBD-II port, which is generally 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 instructions to read and record any error codes.
Clear the error codes from the OBD-II scanner to reset the check engine light.

3. Disconnect the Battery (Optional)

If preferred or if the scanner method does not work:
- Use a socket set to loosen and remove the negative battery terminal.
- Wait for at least 10 minutes to ensure the vehicle’s electronic systems reset.
Reconnect the negative battery terminal and ensure it is securely fastened.

4. Verify Reset

Start the engine and check if the check engine light is off.
If the light remains on, re-scan with the OBD-II scanner to ensure no persistent error codes are present.
