Functional networking
After being recorded and processed, the data from the steering column switch cluster (SZL) are relayed to the appropriate control units via FlexRay. The steering column switch cluster (SZL) can be assessed with the diagnosis system via the central gateway module (ZGM). Information on the diagnosis can be called up via the FlexRay.
