Abstract: A method for changing a software in the memory of an electronic control unit. A bypass routine is stored in the working memory of the electronic control unit, and the address of the bypass function is stored in a table. A service function reads the address from the table and calls the bypass routine. The bypass routine is replaceable at the run time of the electronic control unit by erasing the table entry. The call of the service function is integrated into the program code of the electronic control unit by an overlay memory, a memory management unit, or with the aid of watch points.
