HINT:

The names of ECUs and sensors shown on the Techstream display may differ from those shown in the DTC Table by ECU information.

CAN BUS CHECK

HINT:

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

Using the Techstream, 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.
Refer to SYSTEM DIAGRAM [12/2017 - 08/2019]

HINT:

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.

HINT:

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 Techstream, check the central gateway ECU and the V bus branch lines for a malfunction.

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

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.

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 simulating 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.

HINT:

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

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 which is not displayed) is suspected.

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.

HINT:

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.

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

*a	Not displayed or background color changes to red

HINT:

In the CAN bus check, it is possible to confirm the communication status of ECUs connected to the bus 2 after connecting the Techstream 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.

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 lines of ECU G on the non-bus 2

Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

*a	Background color changes to red

HINT:

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.)

If both of the bus 2 main bus lines are open, ECUs or sensors that are located farther away from the network 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.)

*g	CAN Bus Check Screen	*h	Network Gateway ECU

HINT:

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

If both of the non-bus 2 main bus lines are open, ECUs that are located farther away from the network 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.)

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

HINT:

When a malfunction occurs on the bus 2, almost all ECUs and sensors in 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.

DTC TABLE BY ECU

HINT:

In the CAN communication system, the CAN communication DTCs of each ECU can be displayed using the Techstream.
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.
Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2015 - 08/2019]
If the system function temporarily returns to normal, DTCs may not be output again even if the following DTC check procedures are used.

CAN BUS WAVEFORMS

HINT:

This waveform is measured between terminals CANH and GND, and terminals CANL and GND of the 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.
Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2015 - 08/2019]
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.

CAN bus waveforms (Group 1)

Normal waveform

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.

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.

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 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.

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.

Open in a CAN main bus line (CANH)

HINT:

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.

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.

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.
