Solution

1. Preparation

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

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 key to the "ON" position without starting the engine.
• Follow the scanner's instructions to retrieve any error codes.

3. Address Underlying Issues

• Review the error codes and check the vehicle's service manual or online resources for troubleshooting steps.
• Complete any necessary repairs based on the error codes (e.g., replace faulty sensors, fix leaks).

4. Clear Error Codes

• With the OBD-II scanner still connected, select the option to clear or reset the error codes.
• Confirm the action when prompted by the scanner.
• Disconnect the scanner from the OBD-II port.
