Precautions for Trouble Diagnosis

INFOID:0000000009163475

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. 

Precautions for Harness Repair

INFOID:0000000009163476

• 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.

SYSTEM DESCRIPTION

CAN COMMUNICATION SYSTEM

System Description

INFOID:0000000009163477

• 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:0000000009163478

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.
