U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000005928107
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 communica tion speed and excellent malfunction detection ability.
Many electronic 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 con-
nected with 2 communication lines (CAN H line, CAN L li ne) 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:0000000005928108
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1000 CAN COMM CIRCUIT” wit h CONSULT-III or 12th judgement flicker without
CONSULT-III is detected when TCM cannot communicate to other control units.
Possible CauseINFOID:0000000005928109
Harness or connector
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005928110
CAUTION:
If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Touch “START”.
4. Wait at least 6 seconds or start engine and wait for at least 6 seconds.
5. If DTC is detected, go to AT-89, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1. Turn ignition switch ON.
2. Wait at least 6 seconds or start engine and wait at least 6 seconds.
3. Perform self-diagnosis. Refer to AT-82, "
Diagnosis Procedure without CONSULT-III".
4. If DTC is detected, go to AT-89, "
Diagnosis Procedure".

6. The self-diagnostic results are displayed. • When “NO DTC IS DETECTED” is displayed, check the ABS warning lamp, SLIP indicator lamp and
VDC OFF indicator lamp.
7. Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Start engine and drive at approximately 30 km /h (19 MPH) for approximately 1 minute.
CAUTION:
• When a wheel sensor “short-circuit” is detected, if the vehicle is not driven at 30 km/h (19 MPH)
for at least 1 minute, the ABS warn ing lamp will not turn off even if the malfunction is repaired.
9. Turn ignition switch OFF to prepare for erasing the memory.
10. Start the engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE” in order on the CONSULT-III screen to erase the error memory.
If “ABS” is not indicated, go to GI-36, "
CONSULT-III Data Link Connector (DLC) Circuit".
CAUTION:
If the error memory is not erased, re -conduct the operation from step 5.
11. For the final inspection, drive at approximately 30 km/h (19 MPH) for approximately 1 minute and confirm
that the ABS warning lamp, SLIP indicator lamp, and VDC OFF indicator lamp are off.
