The personal watercraft vehicle (PWC) component multiplex communication system, as described herein, is configured to accommodate the exchange of information between PWC components. The system employs an engine electronic control unit (ECU), a multipurpose ECU, and a cluster ECU. Management and monitoring data collected from the various PWC components are transmitted to the corresponding ECUs, which process and multiplex the data along with control messages into an aggregate serial data stream and supplies the aggregate data stream to a system bus. System bus interconnects each of the ECUs and accommodates the bi-directional transfer of the aggregate multiplexed data stream to the ECUs and may be configured as a 2-wire interconnection. Accordingly, the ECUs receive and de-multiplex the aggregate data stream containing the data and control messages generated by other ECUs. The control message generation, multiplexing, de-multiplexing, and aggregate data stream transmission and reception operations may be performed in accordance with the Controller Area Network (CAN) protocol. As such, PWC component multiplex communication system facilitates the exchange of data between PWC components without relying on cumbersome conventional wiring harnesses and networks.
