Process for the production of control devices, communicating via a bus of the pharmaceutical, of a.

摘要

The method involves generating a valid diagnostic message using one of several motor-vehicle controllers, in particular using a gateway-controller, where the message is for the other controllers. The message is transmitted to each data bus of the other controllers, where the other controllers exclusively carry out error storage if an error storage function is activated via the diagnostic message. The motor vehicle-controllers communicate via data buses and control functioning of devices such as engine, gear or air conditioning system, of the vehicle.
