CONTROL SYSTEM CONTROLLER AREA NETWORK (CAN) SYSTEM CONSTRUCTION/OPERATION id094000103500 CAN system ! Transmission of information to and from modules is done using time-division multiplexing. ! The signals transmitted from a single module are communicated to all other modules via the twisted pair wiring harnesses.
Page 290 CONTROL SYSTEM Transmission between modules based on time-division multiplexing ! To illuminate 5 individual bulbs, only one communication path from switch to bulb is necessary. ! To illuminate B and C bulbs, the transmitting module combines B and C into a single data, converts data A, D, and E to 0, and then transmits.
