Solution

1. Preparation

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

2. Scan for Error Codes

Plug the OBD-II scanner into the vehicle’s OBD-II port, typically located under the dashboard.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s instructions to read and record any error codes.

3. Disconnect Battery

Using the socket set, loosen the negative terminal (black) of the battery.
Carefully remove the negative cable and ensure it does not touch any metal parts.
Wait for at least 15 minutes to allow the ECU to reset.

4. Reconnect Battery

Reattach the negative battery cable to the terminal and tighten securely.
Ensure that all other battery connections are clean and tight.

5. Verify Reset

Start the engine and allow it to idle for a few minutes.
Monitor the dashboard for the check engine light; it should be off if the reset was successful.
