DTC Combination Table (Open In Can Branch Of Sub Bus 2, Past Communication Error)

  1. Regarding a past communication error of an ECU and sensor connected to sub bus 2 (in this case, normal is displayed when performing the CAN bus check, but communication DTCs are output), determine the part that had a malfunction based on DTCs output from the network gateway ECU.

    HINT: 

    • As gateway function equipped ECUs (sub bus monitor ECUs) monitor signals from all ECUs that are connected to sub buses, gateway function equipped ECUs can detect ECUs with a communication stop more accurately.
    • DTCs output from ECUs other than the network gateway ECU (gateway function equipped ECU) are shown only as a reference.
    • Regarding a communication stop that is currently occurring in sub bus 2, the malfunctioning part can be confirmed easily by performing the CAN bus check using the Techstream.
    • If an open occurs in just one of the lines of a CAN branch, DTCs which are not related to malfunctioning parts may be output (DTCs may be displayed randomly), or a message indicating a communication error may be displayed.
