Solution

1. Preparation

Gather necessary tools: OBD-II scanner, gloves.
Ensure the vehicle is parked on a level surface with the engine off.

2. Check for Codes

Connect the OBD-II scanner to the vehicle's OBD-II port, usually located under the dashboard near the driver's seat.
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s instructions to retrieve any stored codes and record them.

3. Clear the Codes

With the OBD-II scanner still connected, navigate to the option to clear or erase codes.
Confirm the action on the scanner when prompted.

4. Battery Disconnect Method

Turn off the vehicle and ensure all accessories are off.
Using a socket wrench, disconnect the negative terminal of the battery (typically marked with a “-”).
Wait for at least 10 minutes to ensure the ECU fully resets.
Reconnect the negative terminal and tighten securely.

5. Test the Vehicle

Start the engine and allow it to idle for a few minutes.
Monitor the dashboard for the check engine light; it should remain off if the issue has been resolved.
