Solution

1. Preparation

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

2. Address Underlying Issues

If error codes are present, troubleshoot and repair the specific issues (e.g., replace faulty sensors, repair leaks).
Clear any codes using the OBD-II scanner to see if the check engine light reappears after repairs.

3. Reset the Check Engine Light

A. Disconnect Battery

Locate the battery, usually found in the engine bay.
Using a wrench or socket, disconnect the negative terminal first, followed by the positive terminal.
Wait for at least 10 minutes to ensure the ECU resets.

B. Reconnect Battery

Reconnect the positive terminal first, followed by the negative terminal.
Ensure the connections are tight to prevent intermittent issues.

C. Use OBD-II Scanner

Plug the OBD-II scanner into the vehicle’s OBD-II port (usually under the dashboard).
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's instructions to navigate to the "Erase Codes" or "Reset" option.
Confirm the reset and wait for the confirmation message.
