Abstract
The aim of the invention is to improve the diagnosis of motor vehicle systems comprising a plurality of functional components in a network. To this end, the individual status data of the control units (11, 12, 13, 14) is monitored in a central diagnostic control unit (15), optionally using a mathematical model. This is advantageous in that each control unit (11, 12, 13, 14) does not have to be provided with a memory and calculation capacity for the diagnosis.
