Solution

1. Preparation

Gather required tools: OBD-II scanner and possibly a socket set for battery disconnection.
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Address Underlying Issues

Use the OBD-II scanner to read and document any error codes.
Diagnose and rectify any problems indicated by the codes (e.g., replace faulty sensors, fix leaks).

3. Reset the Check Engine Light

Method 1: Using OBD-II Scanner

Insert the OBD-II scanner into the vehicle's OBD-II port (usually located under the dashboard).
Turn the ignition switch to the ON position without starting the engine.
Follow the on-screen instructions of the scanner to navigate to the "Erase Codes" or "Clear DTCs" function.
Confirm the action to clear the codes and reset the check engine light.

Method 2: Disconnecting the Battery

Open the hood and locate the battery.
Using the socket set, disconnect the negative (-) battery terminal first, followed by the positive (+) terminal.
Leave the battery disconnected for at least 15 minutes to allow the ECU to reset.
Reconnect the positive (+) terminal first, then the negative (-) terminal.
Close the hood and start the vehicle to check if the check engine light is off.
