General Description
A communication line exists between the Engine Control Module(ECM) 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. The more information to be communicated, the more wirings is required. In case of CAN communication type, all the information need to be communicated among control modules such as ECM and TCM use CAN lines.
DTC Description
The ECM determines CAN commuication error and sets DTC P0600 if communication with other engine control devices (e.g. TCM, TCS, ABS) via CAN is impossible.
