Solution

1. Preparation

Gather the necessary tools: OBD-II scanner, socket set, and a wrench for battery terminals.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard near the steering column.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner's instructions to read and clear the trouble codes.
Select the option to "Clear Codes" or "Erase Codes."

3. Disconnect Battery (if needed)

Using a socket set, carefully disconnect the negative terminal of the battery.
Wait for at least 5 minutes to allow the ECM to reset.
Reconnect the negative battery terminal and ensure it is secured tightly.

4. Test the System

Start the engine and allow it to idle.
Verify that the check engine light has turned off.
Perform a short test drive to ensure that the light does not reappear.
