Solution

1. Preparation

Tools Required: OBD-II scanner, socket set.
Ensure the vehicle is parked on a level surface and the ignition is turned 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 driver's seat).
Turn the ignition to the "ON" position without starting the engine.
Follow the scanner’s instructions to retrieve and document any error codes.

- Or use the OBD-II scanner to clear the error codes directly.
Follow the scanner’s prompts to clear the codes and reset the check engine light.

5. Reconnect Battery (if applicable)

Reconnect the negative battery terminal, ensuring it is tightened securely.
Check for any loose connections or signs of corrosion.
