To access the computer and diagnostic codes on a 2003 Cadillac DeVille DHS, you'll need an OBD-II scanner. Connect the scanner to the OBD-II port, typically located under the dashboard near the driver's seat. Turn the ignition to the "ON" position without starting the engine, and follow the scanner's instructions to retrieve the diagnostic trouble codes. These codes can help diagnose any issues with the vehicle's systems.
