1. A method of identifying incompatibilities in a bus system of a motor vehicle which has several control devices, the method comprising the acts of:

  • storing control device identification information or an identifier identifying the type of the corresponding control device in a first and in a second control device, the control device identification information or an identifier permits a conclusion on the operating sequences implemented by the corresponding control device and/or on the hardware version of the corresponding control device;

    storing version information identifying the sequence control of the corresponding control device in the first and in the second control device, the version information permits a conclusion on the operating sequences carried out by the corresponding control device and/or on the current status of the sequence control and/or on hardware version of the corresponding control device;

    transmitting, by the first control device, its first control device identification information and/or its first version information to the second control device; and

    accessing, by the second control device, a compatibility reference table which is stored in the second control device, the compatibility reference table indicates which combinations of control device identification information and version information and thus which control devices and their corresponding sequence controls will communicate with the second control device in a compatible manner.
