Solution

1. Preparation

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

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's OBD-II port, usually located under the dashboard near the steering column.
Turn the ignition to the "On" position (do not start the engine) and select the appropriate options on the scanner.
Record any trouble codes displayed.

3. Address Underlying Issues

If codes are present, troubleshoot and repair the issues as needed (e.g., replace faulty sensors, repair exhaust leaks).
If no issues are found or repairs have been made, proceed to reset the check engine light.

4. Reset the Check Engine Light

Disconnect the negative battery terminal using a socket set (typically a 10mm socket).
Wait for at least 15 minutes to ensure the ECU resets.
Reconnect the negative battery terminal and tighten securely.

5. Verify Reset

Start the engine and observe the dashboard for the check engine light.
If the light does not illuminate after a few moments, the reset was successful.
