U1000 CAN COMM CIRCUIT

Description

INFOID:0000000009718322

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009718328

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.

1.

CHECK CAN DIAGNOSIS SUPPORT MONITOR

1.

Select “ABS” and “CAN Diagnosis Support Monitor” in order with CONSULT.

2.

Check the malfunction history between each control unit connected to ABS actuator and electric unit (con-
trol unit).

Check the result of “PAST”

All items are “OK”>>Refer to 

GI-44, "Intermittent Incident"

.

“TRANSMIT DIAG” is other than “OK”>>GO TO 2.
A control unit other than ABS actuator and electric unit (control unit) is anything other than “OK”>>GO TO 3.

2.

CHECK TRANSMITTING SIDE UNIT

Check the ABS actuator and electric unit (control unit) harness connector terminals No. 21 and 23 for damage
or loose connection.

Is the inspection result normal?

YES

>> Erase self-diagnosis results. Then perform self-diagnosis for “ABS” with CONSULT.
