A controller area network diagnosis instrument for diagnosis and evaluation of electronic components on a vehicle control system 10. The controlled area network diagnostic instrument (CANDI) includes a computer processor 119 with a graphics display 121. The processor 119 has a cable 132 to plug into the diagnostic connector 36 engaged to a common data bus 18 of the vehicle 101. The processor 119 is programmed to graphically show a mock gauge cluster or vehicle instrument panel 120 on the display 121 in that has the same appearance as a real vehicle gauge cluster or vehicle instrument panel 102. When connected to the diagnostic connector, the processor 119 mines data off of the data bus 18 and converts it into human readable form on the display 121. This may take the form of mock conventional gauges 124, mock warning lights 105, mock switch status 123, or mock LCD displays 126 shown via computer graphics on the processor's display 121.
