Precautions When Using CONSULT-IINKS004H7
Use CONSULT-II CONVERTER when connecting CONSULT-II to data link connector.
CAUTION:
CAN communication does not function properly if CONSULT-II is used without connecting CONSULT-II
CONVERTER.
Precautions for Trouble DiagnosisNKS004H8
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 RepairNKS004H9
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 communi-
cation line.

SYSTEM DESCRIPTION
Revision: 2007 April2007 M35/M45
SYSTEM DESCRIPTIONPFP:00000
CAN Communication SystemNKS004HA
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
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.

CAN COMMUNICATION CONTROL CIRCUIT
*: These are the only control units wired with both ends of CAN communication system.
SKIB8713E
Component System description
CAN controller It controls CAN communication signal transmission and reception, error detection, etc.
Transceiver ICIt converts digital signal into CAN communication signal, and CAN communication signal into digi-
tal signal.
Noise filter It eliminates noise of CAN communication signal.
Termination circuit
*
(Resistance of approx. 120 Ω)It produces potential difference.
