DTC U1000 CAN COMMUNICATION LINE
Revision: November 20092006 QX56
DTC U1000 CAN COMMUNICATION LINEPFP:23710
DescriptionECS00CEQ
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 LogicECS00CER
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “U1000 CAN COMM CIRCUIT ” with CONSULT-II is detected when TCM cannot
communicate to other control units.
Possible CauseECS00CES
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureECS00CET
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, perform the following procedure to confirm the malfunction is eliminated.
