Check before Engine Is StartedUCS005YD
1. CHECK O/D OFF INDICATOR LAMP
1. Park vehicle on flat surface.
2. Move selector lever to “P” position.
3. Turn ignition switch OFF. Wait at least 5 seconds.
4. Turn ignition switch ON. (Do not start engine.)
Does O/D OFF indicator lamp come on for about 2 seconds?
YES >> 1. Turn ignition switch OFF.
2. Perform self-diagnosis and note NG items.
Refer to CVT-60, "
SELF-DIAGNOSTIC RESULT MODE" .
3. Go to CVT-49, "
Check at Idle" .
NO >> Stop “Road Test”. Go to CVT-180, "

1. CHECK STARTING THE ENGINE
1. Park vehicle on flat surface.
2. Move selector lever to “P” or “N” position.
3. Turn ignition switch OFF.
4. Turn ignition switch START.
Is engine started?
YES >> GO TO 2.
NO >> Stop “Road Test”. Mark the box on the CVT-37, "
DIAGNOSTIC WORKSHEET" . Go to CVT-181,
"Engine Cannot Be Started in “P” and “N” Position" .
2. CHECK STARTING THE ENGINE
1. Turn ignition switch ON.
2. Move selector lever to “D”, “L” or “R” position.
3. Turn ignition switch START.
Is engine started?
YES >> Stop “Road Test”. Mark the box on the CVT-37, "DIAGNOSTIC WORKSHEET" . Go to CVT-181,

DTC U1000 CAN COMMUNICATION LINE
Revision: June 20062007 Versa
DTC U1000 CAN COMMUNICATION LINEPFP:23710
DescriptionUCS005YK
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 LogicUCS005YL

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 CauseUCS005YM
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureUCS005YN
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-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go to CVT-70, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
