PRECAUTION
PRECAUTIONS
Precaution for Trouble DiagnosisINFOID:0000000001374959
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 th
e battery cable from the negative terminal when
checking the harness.
Precaution for Harness RepairINFOID:0000000001374960
• 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 t he 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 DescriptionINFOID:0000000001374961
• CAN communication is a multiplex communication system. This enables the system to transmit and receive
large quantities of data at high speed by connecting c ontrol units with two communication lines (CAN-H and
CAN-L).
• Control units on the CAN network transmit signals us ing the CAN communication control circuit. They
receive only necessary signals from other c ontrol units to operate various functions.
• CAN communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.
System DiagramINFOID:0000000001374962
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.

System description
CAN controller It controls CAN communication signal transmission and reception, error detection, etc.
Transceiver IC It converts digital signal into CAN communication signal, and CAN communication signal into digital
signal.
Noise filter It eliminates noise of CAN communication signal.
Termination circuit
*
(Resistance of approx. 120 Ω) It produces potential difference.
