The multiplex integrated control system sends digital signals between control units through shared wires to reduce the number of wires in order to make harnesses lighter.
The input signals from each switch are converted to digital signals within the receiving control unit. The digital signals are sent from one control unit to another as serial data over dedicated communication lines. When the appropriate control unit receives the digital signal, it converts the signal back to an operational command, such as operating a relay. The multiplex integrated control system schematic shows its power, grounds, and communication lines.
There are two different networks within the multiplex integrated control system
- Body Controller Area Network (B-CAN)
- Fast Controller Area Network (F-CAN)
The body controller area network (B-CAN) and fast controller area network (F-CAN) share information between multiple electronic control units and work together to form the multiplex integrated control system.
The gauge control module translates information from B-CAN to F-CAN and from F-CAN to B-CAN to allow the networks to share information.
