Zusammenfassung:	A control program for an electronic control unit (ECU) is installed at an end of a manufacturing line after the ECU is mounted on an automotive vehicle. The ECU common to all types of vehicles is mounted on each vehicle, and the vehicle type is identified based on data sent from the ECU to a program-installing device. The control program suitable to the identified vehicle type is formulated in the program-installing device by selecting program modules from an object library storing various types of modules and by linking those selected modules into the control program. The control program thus formulated is installed in the ECU at the end of the manufacturing line. In this manner, memory capacities both in the ECU and in the program-installing device are considerably saved.
