Function diagram (Message sequence chart)
The message sequence charts available for a
user function are displayed here. The message sequence charts provide a visual representation of the function. They provide an overview of the control units and other components which are involved in a user function in the specific vehicle. They also show the order in which sig- nals travel between the components concerned.
A blue, broken arrow (1) shows the influence from the circumstances, e.g. the driver turns the starter key.
A blue, continuous arrow (2) shows conven- tional electrics. There must be circuits in the electrical system view to obtain these arrows, e.g. S4 closes + 24 V to E30.
A black arrow (3) displays CAN messages between different control units.
By right-clicking a component (4), you can go to checking the circuit in the electrical system view.
