Based on information received from the system sensors and the control algorithm stored in the memory, the unit generates control actions (in the form of pulses, constant voltages) and information messages (signals to the instrument cluster, to the diagnostic connector, etc.). These signals are sent to actuators and information interface elements both via simple electrical wiring and via a multiplex network (CAN-C).
