CAN BUS CHECK

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 (unstable communication).
   	Not displayed	Either of the following: If a gateway function equipped ECU cannot communicate, the sub bus and ECUs connected to the sub bus will not be displayed. If no ECUs are connected to the sub bus, "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.

   • *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 diag 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.

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 ignition switch to ON (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

   

   *a	Bus 2	*b	Non-bus 2
   *c	Diag Bus	*d	Terminating Resistor
   *e	Location of malfunction	*f	Not displayed or background color changes to red or yellow
   *g	CAN 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 CAN Bus Check screen.

3. 

   *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 CAN Bus Check screen, 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 wire for ECU B on the bus 2

   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 (unstable communication).
   	Not displayed	Either of the following: If a gateway function equipped ECU cannot communicate, sub bus and ECUs connected to the sub bus will not be displayed. If no ECUs are connected to the sub bus, "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.

   • 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 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 CAN Bus Check screen. This indicates a more significant communication stop. In this case, a communication stop of ECU B is suspected.

4. 

   *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 CAN 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 CAN 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 CAN Bus Check screen in the illustration shows that ECU A has a gateway function and a communication stop in ECU A is suspected.

5. 

   *a	Background color changes to red

   If the CAN 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 wires 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 CAN Bus Check screen.

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

   

   *a	Bus 2	*b	Non-bus 2
   *c	Diag Bus	*d	Terminating Resistor
   *e	Location of malfunction	*f	Not displayed or background color is red
   *f	CAN Bus Check screen	*f	Central Gateway ECU

   Tech Tips

   If a communication error occurs in an ECU, it is not displayed on the CAN 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 CAN Bus Check screen.

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

   

   *a	Bus 2	*b	Non-bus 2
   *c	Diag Bus	*d	Terminating Resistor
   *e	Location of malfunction	*f	Not displayed or background color is red
   *g	CAN Bus Check screen	*h	Central Gateway ECU

8. 

   *a	When any of the following malfunctions occur on the bus 2
   *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 CAN 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 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.

21. MILLIMETER WAVE RADAR SENSOR ASSEMBLY (w/ Pre-crash Safety System)

    Tech Tips

    The millimeter wave radar sensor assembly is connected to the CAN communication system but CAN communication DTCs are not stored.

22. Regarding the past communication error of ECUs and sensors connected to the V bus (in this case, normal was displayed when performing the CAN bus check, but communication DTCs are output), the probable CAN branch that had a malfunction can be determined based on the following DTC combination table.

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

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 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.

   • X: DTC is likely output.

   • ▲: DTC is unlikely output.

   • -: DTC is not output.

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