The Ford Fiesta is Ford's most successful selling car, with over 10 million units sold since its inception in 1976. The vehicle is a subcompact car that found most of its success in the European market. More recent models feature a digital display on the dashboard that allows drivers easy access to information about their vehicles. Setting your display to "Self Diagnostic Mode" provides you with pertinent information about how your Fiesta is running and helps you diagnose problems.
