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 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 [07/2015 - ]

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
V Bus	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
Sub bus (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
Sub bus (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 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.

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 sub bus ECUs that are connected to it.
*3: Gateway function equipped ECU that memorizes the sub bus 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 DLC3 branch and the V bus main bus 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 engine 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.

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 B on the V bus

HINT:

When there are communication stops, ECUs are present in the vehicle even though they are not 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.

	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, 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.

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 sub bus ECUs that are connected to it.
*3: Gateway function equipped ECU that memorizes the sub bus 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 D (output from the other branch line is unstable) and the communication of ECU C is also unstable. In addition, in this example, ECU C is equipped with a gateway function. Therefore, communication is also unstable between the sub bus ECUs of ECU C and the V bus.
The example in the illustration shows that ECU D is not displayed on the CAN Bus Check screen. This indicates a more significant communication stop. In this case, a communication stop of ECU D is suspected.

If a communication error is indicated on both the V bus and sub bus on the CAN Bus Check screen, suspect any communication stop displayed for the V bus first.

Example: Open in both CAN branch lines of ECU C on the V bus

TEXT IN ILLUSTRATION

*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 V bus after connecting the Techstream to the DLC3. As for sub buses, it is possible to confirm which sub bus connected ECUs can communicate with a gateway function equipped ECU on the V 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 ECU C has a gateway function and a communication stop in ECU C 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 ECU G on the sub bus

TEXT IN ILLUSTRATION

*a Background color changes to red

HINT:
- A communication error in a sub bus does not affect the V bus or 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 V bus main bus lines are open, ECUs or sensors that are located farther away from the DLC3 than the open part will be displayed as a communication stop on the CAN Bus Check screen.

(In this case, ECU A and B 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 V bus, almost all ECUs and sensors on the V 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 V 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 V bus 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.

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.

HINT:

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.

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 Techstream may differ depending on the ECU that stores the DTC. (Regarding output DTCs, refer to step 6 and the DTC chart for each ECU.)

HINT:

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.

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.

HINT:

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

*c	Gateway Function Equipped ECU	*d	Location of Malfunction
*e	V Bus	*f	Sub Bus

NOTE:

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

HINT:

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.
When there is a communication stop for the gateway function equipped ECU (gateway), communication with ECUs connected to other buses such as the V 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.
- 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

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 [07/2015 - ]
If the system function temporarily returns to normal, DTCs may not be output again even though the following DTC check procedures are used.

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

Regarding a past communication error of an ECU and sensor connected to the V bus (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.

HINT:

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 branch and a communication stop that is currently occurring, the malfunctioning part can be confirmed easily by performing the CAN bus check using the Techstream because the ECU or sensor connected to the CAN branch 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 short to ground 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 Techstream screen. In this case, check the resistance of the CAN bus (steps 7 to 9) first. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [07/2015 - ]
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 COMBINATION TABLE (OPEN OR SHORT IN SUB BUS 1, PAST COMMUNICATION ERROR)

Regarding a past communication error of an ECU and sensor connected to the 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).

HINT:

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 the sub bus 1, the malfunctioning part can be confirmed easily by performing the CAN Bus Check using the Techstream.
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.

CAN BUS WAVEFORMS

Fig 11: Identifying CAN BUS Lines
Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

HINT:
- 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 Techstream, check the resistance of the CAN bus using an ohmmeter first. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [07/2015 - ] 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. Normal waveform
    
    Fig 12: Normal Waveform
    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
  2. Open in both of the lines (CANH and CANL) of a CAN branch
    
    Fig 13: Open In Both Of The Lines (CANH And CANL) Waveform
    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    
    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)
    
    Fig 14: Short Between The CAN Bus Lines (CANH And CANL) Waveform
    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    
    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.
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. Open in a CAN branch line (CANH)
    
    Fig 15: Open In A CAN Branch Line (CANH) Waveform
    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    
    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)
    
    Fig 16: Open In A CAN Branch Line (CANL) Waveform
    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    
    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)
    
    Fig 17: Open In A CAN Main Bus Line (CANH) Waveform
    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    
    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.
  4. Short between a CAN bus line (CANH) and ground
    
    Fig 18: Short Between A CAN Bus Line (CANH) And Ground Waveform
    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    
    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
    
    Fig 19: Short Between A CAN Bus Line (CANL) And Ground Waveform
    Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    
    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.

*1: Whether the ECU that sends data is functioning or not can be judged by using the Techstream to check items such as switches or sensors that send signals to the ECU via direct lines.

*2: Although the received contents cannot be checked in the Data List, whether or not the data is received normally can be checked by observing the combination meter assembly.

*3: The combination meter assembly receives a vehicle speed signal from the brake actuator assembly (skid control ECU) and sends the signal to other ECUs.

*4: The main body ECU (multiplex network body ECU) receives a driver seat buckle switch signal from the airbag sensor assembly and sends the signal to other ECUs.

*5: w/ Automatic Headlight Beam Level Control System

*6: w/ Adaptive Front-lighting System

Details of relevant Data List items (Selected system: Engine)

HINT:

Using the Techstream 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.

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.
The actual values may differ from the values listed in the chart under "Results of real-vehicle check" due to climate, weather conditions, etc.
The values listed under "Results of real-vehicle check" are those of an inspection performed in NORMAL mode. The actual values may differ if inspected in ECO or SPORT mode.

HINT:

Normal Condition: If no conditions are specifically stated for "idling", the shift lever should be in N or P, the A/C switch should be off and all accessory switches should be off.

Warm up the engine.
Turn the A/C switch off.
Turn the engine switch off.
Connect the Techstream to the DLC3.
Turn the engine switch on (IG).
Turn the Techstream on.
Enter the following menus: Powertrain / Engine / Data List.

According to the display on the Techstream, read the "Data List".

ENGINE

Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
Vehicle Speed	Vehicle speed/ Min.: 0 km/h (0 mph), Max.: 255 km/h (158 mph)	Actual vehicle speed	This is the current vehicle speed. The vehicle speed is detected using the wheel speed sensors. Vehicle speed data is delayed when it is displayed. Therefore, even if the vehicle speed listed in the freeze frame data is 0 km/h (0 mph), this does not always mean that the malfunction occurred when the vehicle was stopped. To accurately confirm whether the vehicle was stopped or not, use "SPD (NO)", which is the automatic transaxle output speed.
Engine Speed	Engine speed/ Min.: 0 rpm, Max.: 16383 rpm	600 to 700 rpm: Idling	When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
Coolant Temp	Coolant temperature/ Min.: -40°C (-40°F), Max.: 140°C (284°F)	75 to 100°C (167 to 212°F): After warming up	This is the engine coolant temperature. HINT: After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F). After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature are approximately equal. If the value is -40°C (-40°F), or higher than 135°C (275°F), the sensor circuit is open or shorted. Check if the engine overheats when the value indicates higher than 135°C (275°F).
Battery Voltage	Battery voltage/ Min.: 0 V, Max.: 65.535 V	11 to 14 V: Idling	If 11 V or less, characteristics of some electrical components may change.
Accelerator Position	Accelerator pedal position/ Min.: 0%, Max.: 399.9%	Actual accelerator pedal position	This is the accelerator pedal position defined using the learned fully released position (sensor output) of accelerator pedal position sensor No. 1 as 0% and the fully depressed position as 100%.
Neutral Position SW Signal	Park/neutral position switch status/ ON or OFF	ON: Shift lever in P or N	-
Ambient Temp for A/C	Ambient temperature for A/C/ Min.: -40°C (-40°F), Max.: 215°C (419°F)	-	-
