Abstract

Method and apparatus for programming at least one control device in a vehicle having a plurality of control devices to be programmed, and a central control device with a non-volatile vehicle configuration memory. A bus system connects all the control devices in the vehicle to one another and to the central control device. When one of said control devices is retrofitted or replaced, it initiates a comparison of data located in its memory with the vehicle configuration data resident in the configuration memory of the central control device and, in the case of differences between these data, the data in the retrofitted or replaced control device are overwritten with current vehicle configuration data called up from the vehicle configuration memory.
