CAN COMMUNICATION SYSTEM DTC COMBINATION TABLE


  1. HOW TO INTERPRET COMMUNICATION DTCS (DTCS THAT START WITH U)


    1. If a CAN communication error cannot be reproduced, determine the suspected malfunctioning part using the DTCs stored in ECUs that are connected to the CAN buses by following the procedure below.

      Tech Tips

      Communication DTCs (DTCs that start with U) indicate a communication error between the ECU that stores the DTC and the ECU that is indicated by the DTC.


      1. If multiple ECUs store a communication DTC for a particular ECU, a communication stop of the ECU is suspected.

        Note


        • This DTC table is from another model, and is only used here to show an example of DTCs that are output when there is an open in a CAN branch line for the main body ECU. This table does not show DTCs applicable to this vehicle.

        • Even though a DTC title may indicate a communication error with a specific ECU, the ECU name used in the DTC name on the GTS may differ depending on the ECU that stores the DTC. (Regarding output DTCs, refer to DTC Table by ECU.)

        Tech Tips

        As multiple ECUs indicate a communication stop with the main body ECU, the possibility of a communication stop of the main body ECU is high.

      2. If almost all of the communication DTCs of an ECU are stored, a communication stop of the ECU is suspected.

        Note


        • This DTC table is from another model, and is only used here to show an example of DTCs that are output when there is an open in a CAN branch line for the main body ECU. This table does not show DTCs applicable to this vehicle.

        • Even though a DTC title may indicate a communication error with a specific ECU, the ECU name used in the DTC name on the GTS may differ depending on the ECU that stores the DTC. (Regarding output DTCs, refer to DTC Table by ECU.)

        Tech Tips


        • If almost all of the DTCs of the main body ECU are stored, the possibility of a communication stop of the main body ECU is high.

        • When a CAN communication error occurs, many DTCs are output. DTCs other than communication error DTCs (such as DTCs that start with C or B) and communication DTCs for the ABS system are important DTCs, however it may be easier to determine the malfunctioning part by examining the overall situation without considering these DTCs.

    2. To help determine the part of the sub bus that has a communication error, prioritize the communication stop DTCs stored in the gateway function equipped ECU.

      *c Gateway Function Equipped ECU *d Location of Malfunction
      *e Bus *f Sub Bus

      Note

      This DTC table is from another model, and is only used here to show the ECUs connected to both a bus and a sub bus. It shows DTCs output when there is an open in the main bus lines for the ECM on the sub bus. This table does not show DTCs applicable to this vehicle.

      Tech Tips


      • As gateway function equipped ECUs (sub bus monitor ECU) monitor signals from all ECUs that are connected to sub bus, gateway function equipped ECUs can detect ECUs with a communication stop more accurately.

      • When there is a communication stop for the gateway function equipped ECU (gateway), communication with ECUs connected to other buses such as the bus 2 stops. Therefore, communication DTCs for ECUs connected to other buses are also stored.

    3. When any of the following malfunctions occurs, many DTCs are likely to be output from many ECUs. Because of this, it may be difficult to determine the probable malfunctioning part.


      • Short between CAN lines (CANH and CANL)

      • Short between a CAN line (CANH or CANL) and ground

      • Short between a CAN line (CANH or CANL) and +B

      • Open in a CAN branch line (CANH or CANL) of an ECU or sensor

      • Open in a CAN main bus line (CANH or CANL) between 2 ECUs that have a terminating resistor

  2. DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 2, PAST COMMUNICATION ERROR) (for LHD)


    1. Regarding a past communication error of an ECU and sensor connected to the bus 2 (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.

      Tech Tips


      • 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 GTS because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor name will not be displayed on the screen).

      • ○: DTC is 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.

      • If an open in a CAN main bus line, a short between the CAN bus lines (CANH and CANL) or a short to ground or +B 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 GTS screen. In this case, check the resistance of the CAN bus (steps 9 to 17) first.

      • 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.

  3. DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 3, PAST COMMUNICATION ERROR) (for LHD)


    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.

      Tech Tips


      • 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 GTS because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor name will not be displayed on the screen).

      • ○: DTC is 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.

      • If an open in a CAN main bus line, a short between the CAN bus lines (CANH and CANL) or a short to ground or +B 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 GTS screen. In this case, check the resistance of the CAN bus (steps 9 to 17) first.

      • 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.

  4. DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 5, PAST COMMUNICATION ERROR) (for LHD)


    1. Regarding a past communication error of an ECU and sensor connected to the bus 5 (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.

      Tech Tips


      • 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 GTS because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor name will not be displayed on the screen).

      • ○: DTC is 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.

      • If an open in a CAN main bus line, a short between the CAN bus lines (CANH and CANL) or a short to ground or +B 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 GTS screen. In this case, check the resistance of the CAN bus (steps 9 to 17) first.

      • 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.

  5. DTC COMBINATION TABLE (OPEN OR SHORT IN SUB BUS 1, PAST COMMUNICATION ERROR) (for LHD)


    1. Regarding a past communication error of an ECU and sensor connected to the sub bus 1 (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.

      Tech Tips


      • 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 GTS because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor name will not be displayed on the screen).

      • ○: DTC is 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.

      • 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.

  6. DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 2, PAST COMMUNICATION ERROR) (for RHD)


    1. Regarding a past communication error of an ECU and sensor connected to the bus 2 (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.

      Tech Tips


      • 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 GTS because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor name will not be displayed on the screen).

      • ○: DTC is 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.

      • If an open in a CAN main bus line, a short between the CAN bus lines (CANH and CANL) or a short to ground or +B 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 GTS screen. In this case, check the resistance of the CAN bus (steps 9 to 17) first.

      • 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.

  7. DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 3, PAST COMMUNICATION ERROR) (for RHD)


    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.

      Tech Tips


      • 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 GTS because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor name will not be displayed on the screen).

      • ○: DTC is 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.

      • If an open in a CAN main bus line, a short between the CAN bus lines (CANH and CANL) or a short to ground or +B 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 GTS screen. In this case, check the resistance of the CAN bus (steps 9 to 17) first.

      • 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.

  8. DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 5, PAST COMMUNICATION ERROR) (for RHD)


    1. Regarding a past communication error of an ECU and sensor connected to the bus 5 (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.

      Tech Tips


      • 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 GTS because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor name will not be displayed on the screen).

      • ○: DTC is 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.

      • If an open in a CAN main bus line, a short between the CAN bus lines (CANH and CANL) or a short to ground or +B 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 GTS screen. In this case, check the resistance of the CAN bus (steps 9 to 17) first.

      • 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.

  9. DTC COMBINATION TABLE (OPEN OR SHORT IN SUB BUS 1, PAST COMMUNICATION ERROR) (for RHD)


    1. Regarding a past communication error of an ECU and sensor connected to the sub bus 1 (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.

      Tech Tips


      • 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 GTS because the ECU or sensor connected to the CAN branch line does not respond (the ECU or sensor name will not be displayed on the screen).

      • ○: DTC is 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.

      • 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.
