Claim 0:
1. A method for controlling a data interchange between a control device of a motor vehicle and an external device, the control device comprising a plurality of vehicle functions each assigned to at least one subservice, the method comprising:
receiving a deactivation signal for a first vehicle function of the plurality of vehicle functions, and deactivating the first vehicle function;
checking whether the at least one subservice assigned to the deactivated first vehicle function is assigned to a second vehicle function of the plurality of vehicle functions, the second vehicle function being currently activated;
deactivating the at least one subservice if the at least one subservice is not assigned to the second vehicle function; and
terminating the data interchange between the control device and the external device carried out by the at least one subservice;
wherein:
the data interchange between the control device and the external device takes place independently and regardless of whether the first vehicle function is currently activated or deactivated,
corresponding data collection and data transmission from the control device to the external device occurs as a result of an activated sub service, even if the first vehicle function is not currently activated,
a link between each of the plurality of vehicle functions and the at least one subservice is stored in the control device, and
the checking whether the at least one subservice assigned to the deactivated first vehicle function is assigned to the second vehicle function is based on the stored link.
