Abstract
An engine control unit for a vehicle control unit arrangement is preconfigured to perform a plurality of functions and configures its own range of functions by activating selected preconfigured functions as well as a method for the manipulation-proof configuration of the engine control unit. To activate a preconfigured function, the engine control unit issues a signal for detecting the presence of component control units connected to it. It then requests an item of information for activating a function preconfigured in the control unit from a component control unit that was detected. After receiving an item of activation information, it activates the corresponding preconfigured function.
