How to Use "Communication Bus Check (Detail)" Screen in Inspection

(a) If the CAN communication system is currently normal but has communication stop history, determine the malfunctioning part using Communication Bus Check (Detail) as follows:

NOTICE:

The following CAN bus wiring diagram or communication bus check screen is provided only as an example. This wiring diagram or screen differs from the actual one for this vehicle.
The Lost Communication Time column displays the longest period of time in seconds that the central gateway ECU (network gateway ECU) detected a communication stop in the respective ECU or sensor.
The Lost Communication Trip column displays the trip in which the central gateway ECU (network gateway ECU) detected the longest communication stop in the respective ECU or sensor.
When using the combo box, it may be possible to select a sub bus from the drop down list that does not have any connected ECUs or sensors. This is not a malfunction and occurs when there is no optional device connected to a sub bus which is monitored by a sub bus monitoring ECU (gateway function equipped ECU).
In the drop down list, all sub buses applicable to the model are displayed (e.g. LIN communication sub buses are also displayed). For information on sub buses necessary to diagnose CAN communication system, refer to the System Diagram.

HINT:

If the CAN communication system is currently malfunctioning, it is recommended to use Communication Bus Check rather than Communication Bus Check (Detail) for determining the suspected area.
The communication error history of ECUs or sensors which have communication error history can be displayed on the "Communication Bus Check (Detail)" screen.
Lost Communication Time and Lost Communication Trip are only displayed for the central bus.
Lost Communication Time and Lost Communication Trip are not displayed for sub buses.

(b) If there is an ECU or sensor displayed with a red background on the "Communication Bus Check (Detail)" screen to indicate that it was not communicating, it is suspected that the ECU or sensor was not communicating.

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.

(ah) Central Gateway ECU (Network Gateway ECU) / Techstream Display "Central Gateway"

HINT:

The central gateway ECU (network gateway ECU) is connected to the CAN communication system, but the central gateway ECU (network gateway ECU) does not store or output CAN communication DTCs.

(ai) Steering Sensor / Techstream Display "Steering Angle Sensor"

HINT:

The steering sensor is connected to the CAN communication system, but the steering sensor does not store or output CAN communication DTCs.

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.
