DTC Combination Table (Open Or Short In Bus 3, Past Communication Error)

  1. Regarding a past communication error of an ECU and sensor connected to the bus 3 (in this case, normal is displayed when performing the CAN bus check, but communication DTCs are output), the probable CAN bus line(s) that had a malfunction can be determined based on the following DTC combination table.

    HINT: 

    • Based on the table below and DTCs output from ECUs connected via CAN communication, the probable part for which communication stop occurred can be determined.
    • Regarding an open in a CAN branch line and a communication stop that is currently occurring, the malfunctioning part can be confirmed easily by performing the CAN bus check using the Techstream because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor has a background color of red).
    • ◦: DTC is output.
    • -: DTC is not output.
    • *1: DTC U0073 may be stored when communication is lost.
    • *2: Gateway function equipped ECUs relay signals between the ECUs connected to the different buses.
    • If an open occurs in just one of the wires of a CAN branch line, 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.
    • If an open occurs in just one of the wires of a CAN branch line, even if the values in the following tables are "-", DTCs which are not related to malfunctioning parts may be output, or a message indicating a communication error may be displayed.
