  4. CAN BUS CHECK

    Tech Tips

    The ECUs and sensors that are properly connected to the CAN communication system can be displayed using the GTS.


    1. Using the GTS, select "CAN Bus Check" from "System Select".

      Tech Tips

      Different connection statuses are indicated by the background color of ECUs and sensors that are displayed.

      Explanation of CAN Bus Check screen
      Bus Type Background Color Connection Status
      Bus 2 White Communication has been normal since the start of the CAN bus check.
      Yellow Communication stop occurred at least once since the start of the CAN bus check, but communication is currently occurring (unstable communication).
      Red Communication was established at least once since the start of the CAN bus check, but communication is currently not occurring (unstable communication).
      Not displayed Communication stop has continued since the start of the CAN bus check.*1

      Non-bus 2

      (gateway function equipped ECU that does not have history of connected ECUs)*2

      White Communication has been normal since the start of the CAN bus check.
      Yellow Communication stop occurred at least once since the start of the CAN bus check, but communication is currently occurring (unstable communication).
      Red Communication was established at least once since the start of the CAN bus check, but communication is currently not occurring (unstable communication).
      Not displayed Communication stop has continued since the start of the CAN bus check.*1

      Non-bus 2

      (gateway function equipped ECU that has history of connected ECUs)*3

      White Communication has been normal since the start of the CAN bus check.
      Yellow Communication stop occurred at least once since the start of the CAN bus check, but communication is currently occurring (unstable communication).
      Red

      Currently not communicating (either of the following):


      • Communication stop has continued since the start of the CAN bus check.

      • Communication was established at least once since the start of the CAN bus check, but communication is currently not occurring.

      Not displayed

      Either of the following:


      • If a gateway function equipped ECU cannot communicate, the non-bus 2 and ECUs connected to the non-bus 2 will not be displayed.

      • If no ECUs are connected to the non-bus 2, "There is no system found on the Communication Bus" will be displayed.

      Tech Tips


      • Gateway function equipped ECUs relay signals between the ECUs connected to the different buses.

      • *1: ECUs that are present in the vehicle but are not displayed on the CAN Bus Check screen.

      • *2: Gateway function equipped ECU that does not memorize the non-bus 2 ECUs that are connected to it.

      • *3: Gateway function equipped ECU that memorizes the non-bus 2 ECUs that are connected to it.

      • If none of the connected ECUs are displayed, or there is no response from the vehicle to the GTS, check the central gateway ECU and the V bus main bus lines for a malfunction.

    2. Observe the connection response screen for approximately 2 minutes to check for a change in connection status of the connected ECUs and sensors.

      Tech Tips


      • If an open occurs in one of the lines of a CAN branch (except DLC3), output from the other branch line (the line that is not open) will be unstable and it may interfere with the response (display) of other ECUs and sensors.

      • If the connection status changes during the inspection, repair the open in the branch line of the ECU or sensor that does not respond (is not detected) and then perform the CAN bus check again.

  5. HOW TO INTERPRET CAN BUS CHECK SCREEN


    1. When a communication stop is currently occurring, the probable malfunctioning part can be determined from the CAN bus check and by using the following methods.

      Note

      The following CAN bus wiring diagram is provided only as an example. This wiring diagram is different from the actual wiring diagram for this vehicle.

      Tech Tips


      • When a communication stop is currently occurring, it is easier to determine the probable malfunctioning part from the CAN bus check rather than from communication DTCs.

      • Wait for approximately 2 minutes after turning the power switch on (IG) (or simulate the driving conditions that enable the malfunction to be reproduced) and select the CAN bus check. Then observe the communication status of each ECU on the screen.

    2. If a communication error of only 1 ECU or sensor is indicated on the CAN Bus Check screen, a communication stop of the ECU or sensor is suspected.

      Example: Open in both CAN branch lines of ECU D on the bus 2

      A000836E08
      Text in Illustration
      *a Bus 2 *b Non-bus 2
      *c V Bus *d Terminating Resistor
      *e Location of malfunction *f Not displayed or background color changes to red or yellow
      *g Communication Bus Check screen *h Central Gateway ECU

      Tech Tips

      When there are communication stops, ECUs are present in the vehicle even though they are not displayed on the Communication Bus Check screen.

      Text in Illustration
      *a Background color periodically changes to yellow or red
      *b Not displayed or background color is yellow or red
      *c Not displayed

      If communication errors for multiple ECUs or sensors are indicated on the Communication Bus Check screen, then a communication stop of the ECU or sensor that shows a more serious communication stop (an ECU or a sensor which is not displayed) is suspected.

      Example: Open in a CAN branch line for ECU B on the bus 2

      Explanation of Bus Check (Communication Bus Check) screen
      Bus Type Background Color Connection Status
      Bus 2 White Communication has been normal since the start of the communication bus check.
      Yellow Communication stop occurred at least once since the start of the communication bus check, but communication is currently occurring (unstable communication).
      Red Communication was established at least once since the start of the communication bus check, but communication is currently not occurring (unstable communication).
      Not displayed Communication stop has continued since the start of the communication bus check.*1

      Non-bus 2

      (gateway function equipped ECU that does not have history of connected ECUs)*2

      White Communication has been normal since the start of the communication bus check.
      Yellow Communication stop occurred at least once since the start of the communication bus check, but communication is currently occurring (unstable communication).
      Red Communication was established at least once since the start of the communication bus check, but communication is currently not occurring (unstable communication).
      Not displayed Communication stop has continued since the start of the communication bus check.*1

      Non-bus 2

      (gateway function equipped ECU that has history of connected ECUs)*3

      White Communication has been normal since the start of the communication bus check.
      Yellow Communication stop occurred at least once since the start of the communication bus check, but communication is currently occurring (unstable communication).
      Red

      Currently not communicating (either of the following):


      • Communication stop has continued since the start of the communication bus check.

      • Communication was established at least once since the start of the communication bus check, but communication is currently not occurring.

      Not displayed

      Either of the following:


      • If a gateway function equipped ECU cannot communicate, the non-bus 2 and ECUs connected to the non-bus 2 will not be displayed.

      • If no ECUs are connected to the non-bus 2, "There is no system found on the Communication Bus" will be displayed.

      Tech Tips


      • Gateway function equipped ECUs relay signals between the ECUs connected to the different buses.

      • *1: ECUs that are present in the vehicle but are not displayed on the Communication Bus Check screen.

      • *2: Gateway function equipped ECU that does not memorize the non-bus 2 ECUs that are connected to it.

      • *3: Gateway function equipped ECU that memorizes the non-bus 2 ECUs that are connected to it.

      • The example of the Communication Bus Check screen in the illustration shows the result of electrical noise on the CAN bus which is caused by an open in a CAN branch line of ECU B (output from the other branch line is unstable) and the communication of ECU A is also unstable. In addition, in this example, ECU A is equipped with a gateway function. Therefore, communication is also unstable between the non-bus 2 ECUs of ECU A and the bus 2.

      • The example in the illustration shows that ECU B is not displayed on the Communication Bus Check screen. This indicates a more significant communication stop. In this case, a communication stop of ECU B is suspected.

    4. A0003QGE12
      Text in Illustration
      *a Not displayed or background color changes to red

      If a communication error is indicated on both the bus 2 and non-bus 2 on the Communication Bus Check screen, suspect any communication stop displayed for the bus 2 first.

      Example: Open in both CAN branch lines of ECU A on the bus 2

      Tech Tips


      • In the communication bus check, it is possible to confirm the communication status of ECUs connected to the bus 2 after connecting the GTS to the DLC3. As for non-bus 2, it is possible to confirm which non-bus 2 connected ECUs can communicate with a gateway function equipped ECU on the bus 2.

      • If a gateway function equipped ECU has a communication error, ECUs connected to the gateway function equipped ECU are also affected, and communication stops will be indicated.

      • The Communication Bus Check screen in the illustration shows that ECU A has a gateway function and a communication stop in ECU C is suspected.

    5. A0003EXE11
      Text in Illustration
      *a Background color changes to red

      If the Communication Bus Check screen indicates a communication stop only in the non-bus 2, a communication stop in the non-bus 2 is suspected.

      Example: Open in both CAN branch lines of ECU G on the non-bus 2

      Tech Tips


      • A communication error in a non-bus 2 does not affect the bus 2 or other buses.

      • When a gateway function equipped ECU has memorized the ECUs that are connected to the non-bus 2, if any of the ECUs connected to the gateway function equipped ECU has a communication error, the background color changes to yellow or red. (The displayed name will not disappear.)

    6. If both of the bus 2 main bus lines are open, ECUs or sensors that are located farther away from the central gateway ECU than the open part will be displayed as a communication stop on the Communication Bus Check screen.

      (In this case, ECU D and E are not displayed or their background color changes to red.)

      *c V Bus *d Terminating Resistor
      *e Location of malfunction *f Not displayed or background color is red
      *g Communication Bus Check screen *h Central Gateway ECU

      Tech Tips

      If a communication error occurs in an ECU, it is not displayed on the Communication Bus Check screen even though the ECU is present.

    7. If both of the non-bus 2 main bus lines are open, ECUs that are located farther away from the central gateway ECU than the open part will be displayed as a communication stop on the Communication Bus Check screen.

      (In this case, ECU I and J are not displayed or their background color changes to red.)

      *b When any of the following malfunctions occur on a non-bus 2
      *c Not displayed

      When any of the following malfunctions occur, CAN communication cannot be established and almost all ECUs and sensors on the bus show a communication error on the Communication Bus Check screen.

      Details of Malfunction
      Short between CAN lines (CANH and CANL)
      Short between a CAN line (CANH or CANL) and +B
      Short between a CAN line (CANH or CANL) and ground
      Open in a CAN main bus line

      Tech Tips


      • When a malfunction occurs on the bus 2, almost all ECUs and sensors on the bus 2 and non-bus 2 indicate a communication error (almost all ECUs are not displayed). As communication with the gateway function equipped ECU that is connected to the bus 2 stops, communication from the ECUs connected to the non-bus 2 that is monitored by the gateway function equipped ECU also stops (these ECUs are not displayed).

      • When a malfunction occurs in a non-bus 2, almost all ECUs connected to the non-bus 2 indicate a communication error.

      • A communication error in a non-bus 2 does not affect the bus 2 or other buses.

      • The malfunctioning part can be determined by checking for a short circuit between CAN bus lines or between a CAN bus line and ground or +B short using an electrical tester.

  6. 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.

        *a Items to be checked - -

        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 step 6 and the DTC chart for each 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.

        A0003OFE05
        Text in Illustration
        *a Items to be checked - -

        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.

        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 non-bus 2 that has a communication error, prioritize the communication stop DTCs stored in the gateway function equipped ECU.

      A0004K6E08
      Text in Illustration
      *a Items to be checked *b ECM
      *c Gateway function equipped ECU *d Location of malfunction
      *e Bus 2 *f Non-bus 2

      Note

      This DTC table is from another model, and is only used here to show the ECUs connected to both a bus 2 and a non-bus 2. It shows DTCs output when there is an open in the main bus lines for the ECM on the non-bus 2. This table does not show DTCs applicable to this vehicle.

      Tech Tips


      • As gateway function equipped ECUs (non-bus 2 monitor ECU) monitor signals from all ECUs that are connected to non-bus 2, 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

  7. DTC TABLE BY ECU

    Note

    If system function temporarily returns to normal, DTCs may not be output again even though the following DTC check procedures are used.

    Tech Tips


    • In the CAN communication system, the CAN communication DTCs of each ECU can be displayed using the GTS.

    • If CAN communication system DTCs are output, the malfunction cannot be determined only by the DTCs. Perform troubleshooting according to How to Proceed with Troubleshooting Click here.

    32. Millimeter Wave Radar Sensor Assembly / GTS Display "-"

      Tech Tips

      The millimeter wave radar sensor assembly is connected to the CAN communication system, but the millimeter wave radar sensor assembly does not store or output CAN communication DTCs.

  8. 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 bus line(s) 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 bus line(s) 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 GTS screen. In this case, check the resistance of the CAN bus (steps 8 to 16) first Click here.

      • If an open occurs in just one of the lines of a CAN bus line(s), 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.

  9. 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 bus line(s) 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 bus line(s) 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 GTS screen. In this case, check the resistance of the CAN bus (steps 8 to 16) first Click here.

      • If an open occurs in just one of the lines of a CAN bus line(s), 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.

      • ○: 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.

  10. 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 bus line(s) 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 bus line(s) 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 GTS screen. In this case, check the resistance of the CAN bus (steps 8to 16) first Click here.

      • If an open occurs in just one of the lines of a CAN bus line(s), 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.

      Tech Tips


      • ○: 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.

  11. DTC COMBINATION TABLE (OPEN IN CAN BRANCH OF SUB BUS 1, PAST COMMUNICATION ERROR) (for LHD)


    1. Regarding a past communication error of an ECU and sensor connected to sub bus 1 (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 main body ECU (multiplex network body ECU).

      Tech Tips


      • 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 main body ECU (multiplex network body ECU) (gateway function equipped ECU) are shown only as a reference.

      • Regarding a communication stop that is currently occurring in sub bus 1, the malfunctioning part can be confirmed easily by performing the CAN bus check using the GTS.

      • 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.

      Tech Tips


      • ○: 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.

  12. 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 bus line(s) 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 bus line(s) 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 GTS screen. In this case, check the resistance of the CAN bus (steps 8 to 16) first Click here.

      • If an open occurs in just one of the lines of a CAN bus line(s), 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.

  13. 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 bus line(s) 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 bus line(s) 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 GTS screen. In this case, check the resistance of the CAN bus (steps 8 to 16) first Click here.

      • If an open occurs in just one of the lines of a CAN bus line(s), 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.

      • ○: 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.

  14. 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 bus line(s) 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 bus line(s) 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 GTS screen. In this case, check the resistance of the CAN bus (steps 8to 16) first Click here.

      • If an open occurs in just one of the lines of a CAN bus line(s), 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.

      • ○: DTC is output.

      • -: DTC is not output.

      • *2: DTC U0073 may be stored when communication is lost.

  15. DTC COMBINATION TABLE (OPEN IN CAN BRANCH OF SUB BUS 1, PAST COMMUNICATION ERROR) (for RHD)


    1. Regarding a past communication error of an ECU and sensor connected to sub bus 1 (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 main body ECU (multiplex network body ECU).

      Tech Tips


      • 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 main body ECU (multiplex network body ECU) (gateway function equipped ECU) are shown only as a reference.

      • Regarding a communication stop that is currently occurring in sub bus 1, the malfunctioning part can be confirmed easily by performing the CAN bus check using the GTS.

      • 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.

    • The following waveform is measured between terminals CANH and GND, and terminals CANL and GND of the DLC3. (Use this as a reference for diagnosis of CAN communication lines.)

    • When malfunctions in multiple ECUs are suspected based on the CAN bus check and DTCs checked using the GTS, check the resistance of the CAN bus using an ohmmeter first Click here. If no problems are found, check the following waveforms.

    • If a waveform is not similar to one of the following 3 patterns (Group 1), then an open in a CAN main bus line, an open in a CAN branch line, or a short between a CAN line (CANH or CANL) and ground is suspected (Group 2).

    • Wiggle the connector and wire harness to check if the waveform changes.


    1. CAN bus waveforms (Group 1)


      1. A000489E08
        *a 1 V/DIV.
        *b 50 μs./DIV.

        Normal waveform

      2. A0008JSE08
        *a 1 V/DIV.
        *b 50 μs./DIV.

        Open in both of the lines (CANH and CANL) of a CAN branch

        Tech Tips


        • Waveforms (waveforms shown using dotted lines) are not present from an ECU or sensor connected to a CAN branch with an open circuit in both lines. (Waveforms from other ECUs or sensors are normal.)

        • Because this waveform is similar to a normal waveform, instead of using the waveform, the malfunctioning part can be narrowed down by performing a CAN bus check.

      3. A0008YZE08
        *a 1 V/DIV.
        *b 50 μs./DIV.

        Short between the CAN bus lines (CANH and CANL)

        Tech Tips


        • Waveforms disappear.

        • If the malfunction is in an ECU, disconnecting the ECU will change the waveform. If the waveform does not change, a malfunction in the wire harness is suspected.

    2. CAN bus waveforms (reference) (Group 2)

      Note

      The following CAN bus waveforms can be used only as reference. The actual measured waveform may differ significantly depending on the location of the open or short circuit.


      1. A00087WE08
        *a 1 V/DIV.
        *b 50 μs./DIV.

        Open in a CAN branch line (CANH)

        Tech Tips


        • An abnormal waveform is output from an ECU with an open in one of its CAN branch lines. Because this abnormal output interferes with the signals from other ECUs, the output of other ECUs will also appear abnormal.

        • Narrow down the malfunctioning part by checking DTCs or performing a CAN bus check, or by checking waveform changes when ECUs or sensors are disconnected. The waveform will change to one for an open in both sides of a CAN branch when the ECU or sensor with an open CAN branch line is disconnected.

      2. A0004YOE08
        *a 1 V/DIV.
        *b 50 μs./DIV.

        Open in a CAN branch line (CANL)

        Tech Tips


        • An abnormal waveform is output from an ECU with an open in one of its CAN branch lines. Because this abnormal output interferes with the signals from other ECUs, the output of other ECUs will also appear abnormal.

        • Narrow down the malfunctioning part by checking DTCs or performing a CAN bus check, or by checking waveform changes when ECUs or sensors are disconnected. The waveform will change to one for an open in both sides of a CAN branch when the ECU or sensor with an open CAN branch line is disconnected.

      3. A0009JRE08
        *a 1 V/DIV.
        *b 50 μs./DIV.

        Open in a CAN main bus line (CANH)

        Tech Tips


        • Waveforms of ECUs or sensors that are closer to the DLC3 than the open part are almost normal.

        • Waveforms of ECUs or sensors that are on the opposite side of the DLC3 from the open part are abnormal.

        • An open in a CAN main bus line can be confirmed by measuring the resistance between the CANH and CANL terminals of any CAN branch.

      4. A0006VCE08
        *a 1 V/DIV.
        *b 50 μs./DIV.

        Short between a CAN bus line (CANH) and ground

        Tech Tips


        • Narrow down the shorted part by checking for waveform changes when disconnecting connectors from the CAN junction connectors or when disconnecting ECUs or sensors.

        • A short to ground in the CANH line can be confirmed by measuring the resistance between CANH and ground using an ohmmeter.

      5. A0006MIE08
        *a 1 V/DIV.
        *b 50 μs./DIV.

        Short between a CAN bus line (CANL) and ground

        Tech Tips


        • Narrow down the shorted part by checking for waveform changes when disconnecting connectors from the CAN junction connectors or when disconnecting ECUs or sensors.

        • A short to ground in the CANL line can be confirmed by measuring the resistance between CANL and ground using an ohmmeter.

    2. Details of relevant Data List items (Selected system: Hybrid Control)

      Note


      • Some Data List values may vary significantly if there are slight differences in the environment in which the vehicle is operating when measurements are obtained. Variations may also occur due to aging of the vehicle. Due to these considerations, it is not always possible to provide definite values to be used for judgment of malfunctions. It is possible that a malfunction may be present even if measured values are within the reference range.

      • In the event of a problem with intricate symptoms, collect sample data from another vehicle of the same model operating under identical conditions in order to reach an overall judgment by comparing all the items in the Data List.

    3. Details of relevant Data List items (Selected system: Power Source Control)

      Note

      In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

      Tech Tips

      Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.


      1. Connect the GTS to the DLC3.

      2. Turn the power switch on (IG).

      3. Turn the GTS on.

      4. Enter the following menus: Body Electrical / Power Source Control / Data List.

      5. According to the display on the GTS, read the Data List.
