DTC U1000 CAN COMMUNICATION LINE
DTC U1000 CAN COMMUNICATION LINE
DescriptionINFOID:0000000001327165
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 malfunction detection ability.
Many electronic control units are equipped onto a vehi cle, and each control unit shares information and links
with other control units during operation (not independent ). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/recei ves data but selectively reads required data only.
On Board Diagnosis LogicINFOID:0000000001327166
Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-III or 17th judgement flicker without
CONSULT-III is detected when TCM cannot communicate to other control units.
Possible CauseINFOID:0000000001327167
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000001327168
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following proc edure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “ECU INPUT SIGNALS” or “MAIN SIGNAL S” in “DATA MONITOR” mode for “TRANSMISSION”
with CONSULT-III.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go to AT-96, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
