Powertrain Control Software: Multiplexing

Multiplexing is the process of communicating several messages over the same signal path. This process allows multiple modules to communicate with each other through the signal path controller area network (CAN and CAN2). Modules communicate with the powertrain control module (PCM) using CAN communications, to determine the priority in which the signals are sent. For additional information, refer to CONTROLLER AREA NETWORK (CAN) .
