DTC Combination Table (Open In Can Branch Of V3 Bus, Past Communication Error)

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 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 does not respond (the ECU or sensor name will not be displayed on the screen).
• If an open in a CAN main bus line, a short between the CAN bus lines (CANH and CANL) or a +B or ground short in the CAN bus occurs, DTCs of almost all ECUs (or sensors) on the CAN bus may be output, or a message indicating a communication error may be displayed on the Techstream screen. In this case, check the resistance of the CAN bus (steps 7 to 9) first.

  Refer to HOW TO PROCEED WITH TROUBLESHOOTING [04/2013 - 10/2016]

• 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.

HINT: 

• ◦: DTC is output.
• X: DTC is likely to be output.
• ←: DTC is unlikely to be output.
• -: DTC is not output.
• *1: Gateway function equipped ECUs relay signals between the ECUs connected to the different buses.
• *2: DTC U0073 may be stored when communication is lost.
