Solution

1. Preparation

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

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, usually 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 record any error codes.

3. Clear Error Codes

Still connected to the OBD-II scanner, navigate to the function for clearing codes.
Select the option to "Erase Codes" or "Clear Codes" and confirm the action.
Wait for the scanner to indicate that the codes have been cleared.

4. Disconnect Battery (if needed)

If the check engine light remains illuminated, disconnect the negative terminal of the battery using a socket wrench.
Leave it disconnected for at least 15 minutes to ensure the ECM resets.
Reconnect the negative terminal and tighten it securely.
