Precautions for Trouble Diagnosis
INFOID:0000000003387561
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:0000000003387562
• 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.

FUNCTION DIAGNOSIS
CAN COMMUNICATION SYSTEM
System Description
INFOID:0000000003387563
• 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.

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.
