DTC U0073: Control Module Communication Bus "A" Off; DTC U0401: Invalid Data Received from ECM/PCM "A"; DTC U0416: Invalid Data Received from Vehicle Dynamics Control Module; DTC U0422: Invalid Data Received from Body Control Module; DTC U0423: Invalid Data Received from Instrument Panel Cluster Control Module [06/2016 - ]: Description

HINT:

Problems on the CAN bus (communication line) can be detected from the DLC3 connector (Except when the DLC3 branch line is open).
By using the Techstream, it is possible to check CAN communication DTC.
The DLC3 is connected to the CAN communication line, but the CAN communication is unable to detect problems on the DLC3 branch line.
