CAN BUS CHECK
Tip:The ECUs and sensors that are properly connected to the CAN communication system can be displayed using the GTS.
Using the GTS, select the CAN Bus Check screen.
Note:It may be possible to select buses that do not have ECUs or sensors from the bus selection pull-down menu. This is not a malfunction. (This occurs when optional devices are not on a sub bus that is monitored by a gateway function equipped ECU.)
In the bus selection pull down menu, all buses applicable to the model are displayed (e.g. LIN communication buses are also displayed). Therefore, refer to the wiring diagrams to check the names of sub buses for CAN communication.
Tip:Different connection statuses are indicated by the background color of ECUs and sensors that are displayed.

Gateway function equipped ECUs relay signals between ECUs and sensors connected to different buses.
*1: An ECU or sensor is installed to the vehicle but is not displayed on the "Communication Bus Check" screen.
*2: The gateway function equipped ECU does not memorize ECUs and sensors connected to its respective sub bus.
*3: The gateway function equipped ECU memorizes ECUs and sensors connected to its respective sub bus.
*4: When the central gateway ECU has an internal malfunction or cannot communicate with the GTS, the name of buses, sub buses, ECUs and sensors will not be displayed.
*5: When no ECUs or sensors are connected to a bus, the message "There is no system found on the communication Bus." will be displayed.
*6: When a gateway function equipped ECU cannot communicate with the central gateway ECU, the name of sub buses and ECUs or sensors connected to the sub bus will not be displayed.
*7: When no ECUs or sensors are connected to the sub bus, the message "There is no system found on the communication Bus." will be displayed.
If there is no communication between the GTS and the vehicle, or no ECUs or sensors are displayed as connected, check the central gateway ECU and V bus (the bus that connects the DLC3 to the central gateway ECU) for malfunctions.
Observe the connection response screen for approximately 2 minutes to check for a change in connection status of the connected ECUs and sensors.
Tip: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.
HOW TO INTERPRET CAN BUS CHECK SCREEN
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.
Tip: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 "CAN Bus Check". Then observe the communication status of each ECU on the screen.
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.

The example of the CAN 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 HV is also unstable. In addition, in this example, MB is equipped with a gateway function. Therefore, communication is also unstable between the Sub bus ECUs of MB and the bus 4.
The example in the illustration shows that HV has a red background color on the CAN Bus Check screen. This indicates a more significant communication stop. In this case, a communication stop of HV is suspected.
If a communication error is indicated on both the bus 4 and Sub bus on the CAN Bus Check screen, suspect any communication stop displayed for the bus 4 first.
Example: Open in both CAN branch lines of MB on the bus 4
*a
Background color is red
*b
Not displayed
Tip:In the CAN bus check, it is possible to confirm the communication status of ECUs connected to the bus after connecting the GTS to the DLC3. As for sub bus, it is possible to confirm which sub bus connected ECUs can communicate with a gateway function equipped ECU on the bus.
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 CAN Bus Check screen in the illustration shows that MB has a gateway function and a communication stop in MB is suspected.
If the CAN Bus Check screen indicates a communication stop only in the sub bus, a communication stop in the sub bus is suspected.
Example: Open in both CAN branch lines of MIR-R on the sub bus

Tip:A communication error in a sub bus does not affect the other buses.
When a gateway function equipped ECU has memorized the ECUs that are connected to the sub bus, 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.)
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 CAN Bus Check screen.

Tip:When a malfunction occurs in the bus, almost all ECUs and sensors on the bus and sub bus indicate a communication error (almost all ECUs are not displayed). As communication with the gateway function equipped ECU that is connected to the bus stops, communication from the ECUs connected to the sub bus that is monitored by the gateway function equipped ECU also stops (these ECUs are not displayed).
When a malfunction occurs in a sub bus, almost all ECUs connected to the sub bus indicate a communication error.
A communication error in a sub bus does not affect the 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.
If a communication error of all ECUs and sensors is indicated on the CAN Bus Check screen, a communication stop of the V bus (DLC3 - central gateway ECU) is suspected.

HOW TO INTERPRET COMMUNICATION DTCS (DTCS THAT START WITH U)
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.
Tip: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.
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 step 6 and the DTC chart for each ECU.)
Tip: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.
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.
Tip: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.
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.

Tip: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 stops. Therefore, communication DTCs for ECUs connected to other buses are also stored.
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.

DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 2, PAST COMMUNICATION ERROR)
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.
Tip: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 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 8 to 16) first.
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.
*: DTC U0073 may be stored when communication is lost.

DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 3, PAST COMMUNICATION ERROR)
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.
Tip: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 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 8 to 16) first.
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.
*: DTC U0073 may be stored when communication is lost.

DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 5, PAST COMMUNICATION ERROR)
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.
Tip: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 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 8 to 16) first.
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.
*: DTC U0073 may be stored when communication is lost.

DTC COMBINATION TABLE (OPEN IN CAN BRANCH OF SUB BUS 1, PAST COMMUNICATION ERROR)
Regarding a past communication error of ECUs and sensors connected to sub bus 1 (in this case, normal is displayed for 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).
Tip:As gateway function equipped ECUs (sub bus monitor ECU) 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 1, the malfunctioning part can be confirmed easily by performing 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.
○: DTC is output.
-: DTC is not output.
*: DTC U0073 may be stored when communication is lost.

CAN BUS WAVEFORMS
Tip:This 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. If no problems are found, check the following waveforms.
Click here
If a waveform is not similar to one of the following 3 patterns (Group 1), then an open in a CAN main wire, an open in a CAN branch wire, or a short between a CAN wire (CANH or CANL) and ground is suspected (Group 2).
Wiggle the connector and wire harness to check if the waveform changes.
CAN bus waveforms (Group 1)
-
Normal waveform
-
Open in both of the lines (CANH and CANL) of a CAN branch
Tip:Waveforms (waveforms shown using dotted lines) are not output 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.
-
Short between the CAN bus lines (CANH and CANL)
Tip: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.
-
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.
-
Open in a CAN branch wire (CANH)
Tip:An abnormal waveform is output from an ECU with an open in one of its CAN branch wires. 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 wire is disconnected.
-
Open in a CAN branch wire (CANL)
Tip:An abnormal waveform is output from an ECU with an open in one of its CAN branch wires. 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 wire is disconnected.
-
Open in a CAN main wire (CANH)
Tip: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 wire can be confirmed by measuring the resistance between the CANH and CANL terminals of any CAN branch.
-
Short between a CAN bus line (CANH) and ground
Tip:Narrow down the shorted part by checking for waveform changes when disconnecting connector(s) from the CAN junction connector(s) 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.
-
Short between a CAN bus line (CANL) and ground
Tip:Narrow down the shorted part by checking for waveform changes when disconnecting connector(s) from the CAN junction connector(s) 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.

Details of relevant Data List items (Selected system: Hybrid 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.
Tip: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.
