NETWORKING CAN COMMUNICATION SYSTEM(for Gasoline Model (NR Series)) DTC COMBINATION TABLE

HOW TO INTERPRET COMMUNICATION DTCS (DTCS THAT START WITH U)

a.

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.

i.

If multiple ECUs store a communication DTC for a particular ECU, a communication stop of the ECU is suspected.

NOTICE:: ·

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 GTS may differ depending on the ECU that stores the DTC. (Regarding output DTCs, refer to DTC Table by ECU.)

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.

b.

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.

NOTICE:: This DTC table is from another model, and is only used here to show the ECUs connected to both a central 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 central bus stops. Therefore, communication DTCs for ECUs connected to other buses are also stored.

c.

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 COMBINATION TABLE (OPEN OR SHORT IN BUS 1, PAST COMMUNICATION ERROR)

a.

If DTCs indicating a past communication error of an ECU or sensor connected to Bus 1 are output (but the bus is normal when performing the CAN bus check), the probable area 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.

·

If there is an open in a CAN branch line or a communication stop is currently occurring, the malfunctioning area can easily be determined by performing a CAN bus check using the GTS to determine which ECU or sensor that is connected to the branch line is not responding (the ECU or sensor has a background color of red).

·

○: DTC is output.

·

-: DTC is not output.

·

*1: Gateway function equipped ECUs relay signals between the ECUs connected to the different buses.

·

*2: DTC U007488 may be stored when communication is lost.

·

If an open occurs in just one of the wires of a CAN branch line, 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.

·

If an open occurs in just one of the wires of a CAN branch line, even if the values in the following tables are "-", DTCs which are not related to malfunctioning parts may be output, or a message indicating a communication error may be displayed.

DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 3, PAST COMMUNICATION ERROR)

a.

If DTCs indicating a past communication error of an ECU or sensor connected to Bus 3 are output (but the bus is normal when performing the CAN bus check), the probable area 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.

·

If there is an open in a CAN branch line or a communication stop is currently occurring, the malfunctioning area can easily be determined by performing a CAN bus check using the GTS to determine which ECU or sensor that is connected to the branch line is not responding (the ECU or sensor has a background color of red).

·

○: DTC is output.

·

-: DTC is not output.

·

*1: Gateway function equipped ECUs relay signals between the ECUs connected to the different buses.

·

*2: DTC U007488 may be stored when communication is lost.

·

If an open occurs in just one of the wires of a CAN branch line, 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.

·

If an open occurs in just one of the wires of a CAN branch line, even if the values in the following tables are "-", DTCs which are not related to malfunctioning parts may be output, or a message indicating a communication error may be displayed.

DTC COMBINATION TABLE (OPEN OR SHORT IN BUS 5, PAST COMMUNICATION ERROR)

a.

If DTCs indicating a past communication error of an ECU or sensor connected to Bus 5 are output (but the bus is normal when performing the CAN bus check), the probable area 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.

·

If there is an open in a CAN branch line or a communication stop is currently occurring, the malfunctioning area can easily be determined by performing a CAN bus check using the GTS to determine which ECU or sensor that is connected to the branch line is not responding (the ECU or sensor has a background color of red).

·

○: DTC is output.

·

-: DTC is not output.

·

*1: Gateway function equipped ECUs relay signals between the ECUs connected to the different buses.

·

*2: DTC U007488 may be stored when communication is lost.

·

If an open occurs in just one of the wires of a CAN branch line, 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.

·

If an open occurs in just one of the wires of a CAN branch line, even if the values in the following tables are "-", DTCs which are not related to malfunctioning parts may be output, or a message indicating a communication error may be displayed.
