SYSTEM DESCRIPTION

SYSTEM DESCRIPTIONPFP:00000
CAN Communication SystemBKS0040R

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.

Component Description
Main line CAN communication line between splices
Branch line CAN communication line between splice and a control unit
Splice A point connecting a branch line with a main line
Termination circuit Refer to LAN-5, "

Information Needed for Trouble DiagnosisBKS0040X
CAN communication system performs trouble diagnosis with the following tools.
How to Use CAN Communication Signal ChartBKS0040Y
The CAN communication signal chart lists the signals needed for trouble diagnosis. It is useful for detecting
the root cause by finding a signal related to the symptom, and by checking transmission and reception unit.
Tool Usage
Interview sheet For filling in vehicle information and interview with customer.
Data sheet For attaching CONSULT-II data or on-board diagnosis data.
Diagnosis sheetFor detecting the root cause. (Diagnosis sheet includes system diagram for every CAN system
type)
