Solution

1. Preparation

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

2. Scan for Trouble Codes

Plug the OBD-II scanner into the vehicle's OBD-II port, usually located beneath the dashboard near the driver's side.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner's instructions to read and record any trouble codes.

3. Address Issues

If any trouble codes are present, diagnose and repair the underlying issues related to these codes.
Confirm that all repairs are completed before proceeding.

4. Clear the Trouble Codes

With the ignition still in the "ON" position, use the OBD-II scanner to navigate to the "Erase Codes" or "Clear Codes" option.
Confirm the action and wait for the scanner to indicate that the codes have been successfully cleared.

5. Verify Reset

Start the engine and observe if the check engine light remains off.
If the light returns, further diagnosis may be needed.
