In the control unit network, important information is transferred across the bus for the function of the control unit.
In the event of implausible or missing messages, a fault is entered in the engine management system. Frequently, the fault must be rectified in the component that caused the fault. The component that caused the fault is a participant in the CAN bus network. This participant can be a control unit or also a component connected to the CAN bus (e.g. steering-angle sensor).
When a fault that arose due to problems in network communication is stored, reference is made to the component that caused the fault.
