How to Erase Self-diagnostic Results
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait for at least
5 seconds and then turn it ON again.
2. Perform AT-90, "
Diagnostic Procedure Without CONSULT-II" .
3. Turn ignition switch OFF. (The self-diagnostic results will be erased.)

DTC U1000 CAN COMMUNICATION LINE
Revision: June 20062007 Versa
DTC U1000 CAN COMMUNICATION LINEPFP:31940
DescriptionUCS005N8
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 LogicUCS005N9

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-II or 12th judgement flicker with-
out CONSULT-II is detected when TCM cannot communicate to other control units.
Possible CauseUCS005NA
Harness or connector
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureUCS005NB
