A computer-based system for providing visual images to assist in the inspection of a vehicle emission-control system and components consists of a database of text and graphics data both for emission-control systems and the individual components thereof accessible on a vehicle model and style basis. A first image provides both graphic and text relating to the complete emission-control system recalled, while highlighting one of the elements both in the text and graphics display. Each component may be highlighted in sequence. A second display may be accessed which provides an enlarged graphical display of the highlighted component with additional text, if required, to provide more detailed position data for the component to aid in the location and inspection of the highlighted component. The system may be accessed through a keyboard or keypad, which also allows the entry of inspection data for storage by the system.
