SYSTEM DESCRIPTION
SYSTEM DESCRIPTION
CAN Communication SystemINFOID:0000000001451946
CAN communication is a multiplex communication syste
m. 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 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.
SKIB8887E
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 "CAN COMMUNICATION CONTROL CIRCUIT".

CAN communication system performs trouble diagnosis with the following tools.
How to Use CAN Communication Signal ChartINFOID:0000000001451953
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 sy mptom, and by checking transmission and reception unit.
To o l U s a g e
Interview sheet For filling in vehicle information and interview with customer.
Data sheet For copying on-board diagnosis data.
Diagnosis sheet For detecting the root cause. (Diagnosis sheet includes system diagram for every CAN system type)
ECU list
(On the “CAN DIAG SUPPORT
MNTR”) For checking the condition of control units and the status of CAN communication.
SELF-DIAG RESULTS
(CONSULT-III)
CAN DIAG SUPPORT MNTR

CAN communication signal
chart For converting information received from a customer into CAN communication signal transmission
and reception. This information can be used to judge whether a circuit between control units is nor-
mal or abnormal.
Abbreviation list For checking abbreviations in CAN communication signal chart and diagnosis sheet.
