1.
OBTAIN INFORMATION ABOUT SYMPTOM
Interview the customer to obtain as much information as possible about the conditions and environment under
which the malfunction occurs.
>> GO TO 2.
2.
CHECK SYMPTOM
• Check the symptom based on the information obtained from the customer.
• Check if any other malfunctions are present.
>> GO TO 3.
3.
CONSULT-III SELF-DIAGNOSIS
Perform “MULTI DISPLAY” “self diagnosis” by connecting CONSULT-III.
NOTE:
If “CAN COM CIRC [U1000]” is displayed, start the diagnosis from the CAN communication system.
.
Is any DTC No. displayed?
YES
>> GO TO 4.
NO

U1000 CAN COMM CIRCUIT
DTC/CIRCUIT DIAGNOSIS
U1000 CAN COMM CIRCUIT
Description
INFOID:0000000006466803
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-board mul-
tiplex communication line with high data communication speed and excellent error detection ability. A modern
vehicle is equipped with many ECUs, and each control unit shares information and links with other control
units during operation (not independent). In CAN communication, 2 control units are connected with 2 commu-
nication lines (CAN-L-line and CAN-H-line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to
LAN-31, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"
for details of the
communication signal.
