1. A method of a vehicle electrical system of a vehicle for handling diagnostics communications with an external diagnostic unit via a vehicle interface, the vehicle electrical system including a plurality of arithmetic logic units electrically communicating with one another internally within the vehicle, the method comprising the following steps being performed by an execution of a diagnostic application on one arithmetic logic unit of the plurality of arithmetic logic units:
receiving, by the diagnostic application, a diagnostic inquiry from the external diagnostic unit without an address identifying any of the plurality of arithmetic logic units;
analyzing, by the diagnostic application, content of the diagnostic inquiry;
based on a result of the analysis of the content of the diagnostic inquiry, determining, by the diagnostic application, at least one of the plurality of arithmetic logic units that is relevant to the diagnostic inquiry; and
based on the determination, performing at least one of the following two steps (a)-(b):
(a) transmitting, by the diagnostic application, a message to the at least one of the arithmetic logic units to obtain diagnostics information to provide to the external diagnostic unit, to control the at least one of the arithmetic logic units to enter a defined state, or to reprogram the at least one of the arithmetic logic units; and
(b) sending a diagnostic response to the external diagnostic unit.
