Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, and safety gloves.
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s OBD-II port, typically located under the dashboard near the steering column.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s instructions to read the codes and clear them if necessary.

3. Disconnect Battery (if no codes)

Open the hood and locate the battery.
Using a socket set, remove the negative battery terminal (black cable) first, followed by the positive terminal (red cable).
Wait for 10-15 minutes to allow the vehicle’s systems to reset.
Reconnect the positive terminal first, followed by the negative terminal.
Tighten the connections securely.

4. Test the Vehicle

Start the engine and observe if the check engine light remains off.
Drive the vehicle for a short distance to ensure the light does not reappear.
