ABSTRACT:
An on-board computer for a motor vehicle is equipped with a microprocessor which acquires input signals from analog or digital generators and derives display values or display data from them. These display values or display data are displayed on a display system assigned to the on-board computer which preferably is arranged within an instrument cluster of the dashboard of the motor vehicle. For the switching-over or for the free selection of a certain, particularly country-specific, set of programs or data or display values or display data, the on-board computer, which is also used as a diagnostic system for several control units installed into the motor vehicle, is switched to a diagnostic mode and the corresponding set of data is selected by means of the function switch of the on-board computer.
