BCM, SJB(Smart Junction Box) and CLU(Instrument Cluster) are connected by CAN line.
The nearest module with input switch or actuator receives the input data to reduce the wiring and then send input data to the others which need them via CAN lines.In case of sending output, it is used to CAN communication, not wiring.
SJB can also control relays and IPS.So Each module allots the current data and actuation data.
