CAN BUS CHECK

HINT:

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

(a) Using the Techstream, select the CAN Bus Check screen.

CAN Bus Check

NOTICE:

  • 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.

Sub bus with a gateway function equipped ECU that memorizes connected ECUs and sensors*3

White

Communication has been normal.

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):

  • Not communicating since the start of the CAN bus check
  • Communication occurred at least once since the start of the CAN bus check, but is currently not occurring.

Not displayed

Either of the following:

  • The gateway function equipped ECU cannot communicate with the central gateway ECU (network gateway ECU).*6
  • No ECUs or sensors are connected to the sub bus.*7
  • 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 (network gateway ECU) has an internal malfunction or cannot communicate with the Techstream, 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 (network 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 Techstream and the vehicle, or no ECUs or sensors are displayed as connected, check the central gateway ECU (network gateway ECU) and V bus (the bus that connects the DLC3 to the central gateway ECU (network gateway ECU)) for malfunctions.

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

HINT:

  • 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

(a) 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.

NOTICE:

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.

HINT:

  • 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.

(b) 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 HV on the bus 4

*a

Bus 2

*b

HINT:

When there are communication stops, ECUs that are present in the vehicle may not be displayed on the CAN Bus Check screen.

(c) If communication errors for multiple ECUs or sensors are indicated on the CAN Bus Check screen, then a communication stop of the ECU or sensor that shows a more serious communication stop (an ECU or sensor whose background color is red) is suspected.

Example: Open in a CAN branch line for HV on the bus 4

*a

Background color is red

*b

Background color intermittently becomes yellow or red

*c

  • *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.
  • 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.

(d) 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

HINT:

  • In the CAN bus check, it is possible to confirm the communication status of ECUs connected to the bus after connecting the Techstream 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.

(e) 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

*a

Background color is red

HINT:

  • 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.

(i) 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 (network gateway ECU)) is suspected.

CAN BUS WAVEFORMS

HINT:

  • The following waveforms are measured between terminals CANH and GND, and terminals CANL and GND of the central gateway ECU (network gateway ECU). (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 Techstream, 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 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.

(a) CAN bus waveforms (Group 1)

(1) Normal waveform

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

HINT:

  • 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) Short between the CAN bus lines (CANH and CANL)

HINT:

  • 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.

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

NOTICE:

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) Open in a CAN branch line (CANH)

HINT:

  • 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) Open in a CAN branch line (CANL)

HINT:

  • 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) Open in a CAN main bus line (CANH)

HINT:

  • Waveforms of ECUs or sensors that are closer to the central gateway ECU (network gateway ECU) than the open part are almost normal.
  • Waveforms of ECUs or sensors that are on the opposite side of the central gateway ECU (network gateway ECU) 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) Short between a CAN bus line (CANH) and ground

HINT:

  • 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) Short between a CAN bus line (CANL) and ground

HINT:

  • 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.
