General Information

U0164 CAN Communication BUS with FATC (Time-out)

General Information

Component Location





General Description

A communication line exists between the Engine Control Module (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 PCM. 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 PCM and FATC control module use CAN lines.

DTC Description

ECU shows U0164 when it doesn't get CAN signal from FATC module.
