DTC U1000 CAN COMMUNICATION LINE
DTC U1000 CAN COMMUNICATION LINE
DescriptionINFOID:0000000001703465
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 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 line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicINFOID:0000000001703466
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-III is detected when TCM cannot
communicate to other control units.
Possible CauseINFOID:0000000001703467
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000001703468
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “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 CVT-58, "
