PRECAUTIONS

Precaution for Trouble Diagnosis

INFOID:0000000005530656

CAUTION:

• Never apply 7.0 V or more to the measurement terminal.

• Use a tester with open terminal voltage of 7.0 V or less.

• Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when

checking the harness. 

Precaution for Harness Repair

INFOID:0000000005530657

• Solder the repaired area and wrap tape around the soldered area.

NOTE:

A fray of twisted lines must be within 110 mm (4.33 in).

• Bypass connection is never allowed at the repaired area.

NOTE:

Bypass connection may cause CAN communication error. The

spliced wire becomes separated and the characteristics of twisted

line are lost. 

• Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communica-

tion line.

CAN COMMUNICATION SYSTEM

FUNCTION DIAGNOSIS

CAN COMMUNICATION SYSTEM

System Description

INFOID:0000000005530658

• CAN communication is a multiplex communication system. This enables the system to transmit and receive

large quantities of data at high speed by connecting control units with two communication lines (CAN-H and

CAN-L).

• Control units on the CAN network transmit signals using the CAN communication control circuit. They

receive only necessary signals from other control units to operate various functions.

• CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.

System Diagram

INFOID:0000000005530659

Each control unit passes an electric current to the termination circuits when transmitting CAN communication

signal. The termination circuits produce an electrical potential difference between CAN-H and CAN-L. CAN

communication system transmits and receives CAN communication signals by the potential difference.

DIAG ON CAN

Description

INFOID:0000000005530661

“Diag on CAN” is a diagnosis using CAN communication instead of previous DDL1 and DDL2 communication

lines, between control units and diagnosis unit.

TROUBLE DIAGNOSIS

Condition of Error Detection

INFOID:0000000005530663

DTC of CAN communication is indicated on SELF-DIAG RESULTS on CONSULT-III if a CAN communication

signal is not transmitted or received between units for 2 seconds or more.

NOTE:

DTCs of CAN communication are as follows:

• U0101

• U0140

• U0164

• U1000

• U1001

CAN COMMUNICATION SYSTEM ERROR

• CAN communication line open (CAN-H, CAN-L, or both)

• CAN communication line short (ground, between CAN communication lines, other harnesses)

• Error of CAN communication control circuit of the unit connected to CAN communication line

WHEN DTC OF CAN COMMUNICATION IS INDICATED EVEN THOUGH CAN COMMUNICATION
SYSTEM IS NORMAL

• Removal/installation of parts: Error may be detected when removing and installing CAN communication unit

and related parts while turning the ignition switch ON. (A DTC except for CAN communication may be

detected.)

• Fuse blown out (removed): CAN communication of the unit may cease.

• Voltage drop: Error may be detected if voltage drops due to discharged battery when turning the ignition

switch ON (Depending on the control unit which carries out CAN communication).

• Error may be detected if the power supply circuit of the control unit, which carries out CAN communication,

malfunctions (Depending on the control unit which carries out CAN communication).

• Error may be detected if reprogramming is not completed normally.

CAUTION:

CAN communication system is normal if DTC of CAN communication is indicated on SELF-DIAG

RESULTS of CONSULT-III under the above conditions. Erase the memory of the self-diagnosis of each

unit.

Symptom When Error Occurs in CAN Communication System

INFOID:0000000005530664

In CAN communication system, multiple units mutually transmit and receive signals. Each unit cannot transmit

and receive signals if any error occurs on CAN communication line. Under this condition, multiple control units

related to the root cause malfunction or go into fail-safe mode.

ERROR EXAMPLE

NOTE:

• Each vehicle differs in symptom of each unit under fail-safe mode and CAN communication line wiring.

• Refer to 

LAN-36, "Abbreviation List"

 for the unit abbreviation.
