A communication line exists between the Engine Control Module(ECM/PCM) and the Transaxle Control Module(TCM). The communication is through a Control Area Network(CAN). Without CAN communication, an independent pin and wiring is needed to receive a sensor information from a ECM/PCM. The more information to be communicated, the more wiring is required. In case of CAN communication type, all the information need to be communicated among control modules such as ECM/PCM and ABS control module use CAN lines.
