GENERAL INFORMATION
CONTROLLER AREA NETWORK (CAN)54C-2
GENERAL INFORMATION
M2542000100159
CAN, an abbreviation for Controller Area Network, is
an ISO-certified international standard for a serial
multiplex communication protocol
*1. A communica-
tion circuit employing the CAN protocol connects
each ECU, and sensor data can be shared among,
which enables more reduction in wiring.
NOTE: *1: The regulations have been decided in
detail, from software matters such as the necessary
transmission rate for communication, the system,
data format, and communication timing control
method to hardware matters such as the harness
type and length and the resistance values.
CAN offers the following advantages.
•Transmission rates are much faster than those in
conventional communication (up to 1 Mbps),
allowing much more data to be sent.
•It is exceptionally immune to noise, and the data
obtained from each error detection device is more
reliable.
•Each ECU connected via the CAN communicates
independently, therefore if the ECU enters dam
-
aged mode, communications can be continued in
some cases.

SELF-DIAGNOSIS
CONTROLLER AREA NETWORK (CAN)54C-6
ERROR DETECTION AND RECOVERY
CAN protocol secures its reliability of communication
by providing several error detection function such as
CRC shown in data frame, and the recovery function
(recovery is performed by resending, from abnormal
state such as transmission errors). If an error is
detected but it is not resolved even after recovery,
communication is stopped. This state is called "Bus
Off."
SELF-DIAGNOSIS
M2542000400280
•CAN self-diagnosis is performed by each ECU
connected to the CAN bus.
•diagnosis codes related to communication are
named with the capital letter U, and are called
"U-codes."
•A summary of the CAN self-diagnosis system is
presented below.
TIME-OUT
Each ECU transmits data frames periodically. If the
data frame is not received within the specified period,
the intended receiving ECU transmits a diagnosis
code indicating communication time-out for the ECU
that failed to transmit.
BUS OFF
Related to a communication error that persists even
after the transmitting ECU attempts recovery for a
specified number of attempts or that persists for a
specified period after recovery, communication is
stopped and this diagnostic code is issued.
FA I L U R E D ATA
When the transmitting ECU detects failure of a sen-
sor directly connected to it, this is the pertinent data
used to inform the ECU.
DATA LENGTH ERROR
When the number of data bytes received is different
from the prescribed number of bytes, this diagnosis
code is issued.
DYNAMIC RANGE ERROR
When the data received is more or less than the pre-
scribed range, this diagnosis code is issued.
CAN BUS DIAGNOSTICS
M2542000500179
As ECUs are connected via CAN bus (including
M.U.T.-III), always diagnose CAN bus to confirm its
normality when inspecting. Simply by performing
M.U.T.-III screen operations, the following inspec
-
tions can be performed automatically, and the result
can be used to verify the CAN bus status.
•Voltage measurement between the CAN_L and
CAN_H and the body earthing terminal
•Resistance measurement between the CAN_L
and CAN_H
•Confirmation of communication of all ECUs
