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.)
11th judgement flicker is longer than others.
Line pressure solenoid valve circuit is short-circuited or discon-
nected.
Go to AT- 1 4 5 , "DTC P0745 LINE PRESSURE SOLENOID
VA LV E" .12th judgement flicker is longer than others.
CAN communication line is damaged.
Go to AT - 9 4 , "DTC U1000 CAN COMMUNICATION LINE" .
Lamp turns off.
Park/neutral position (PNP) switch, overdrive control switch,
closed throttle position signal or wide open throttle position signal
circuit is disconnected or TCM is damaged.
(Because overdrive control switch signal, closed throttle position
signal and wide open throttle position signal are input via CAN
communication line malfunction may continue after self-diagno-
sis.)
Go to AT- 2 2 7 , "TCM Self-diagnosis Does Not Activate" . OD OFF indicator lamp

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
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-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
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-96, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
WITHOUT CONSULT-II
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-90, "
Diagnostic Procedure Without CONSULT-II" .
4. If DTC is detected, go to AT-96, "
Diagnostic Procedure" .

Diagnostic ProcedureUCS005ND
1. CHECK CAN COMMUNICATION CIRCUIT
With CONSULT-II
1. Turn ignition switch ON and start engine.
2. Select “SELF-DIAG RESULTS” mode for “A/T” with CONSULT-
II.
Is any malfunction of the
“U1000 CAN COMM CIRCUIT” indicated?
YES >> Print out CONSULT-II screen, Go to LAN section. Refer

DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCHPFP:32006
DescriptionUCS005NE
The PNP switch assembly includes a transaxle range switch.
The transaxle range switch detects the selector lever position and sends a signal to the TCM.
CONSULT-II Reference ValueUCS005NF
On Board Diagnosis LogicUCS005NG
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P0705 PNP SW/CIRC” with CONSULT-II is detected when TCM does not
receive the correct voltage signal from the switch based on the gear position.
Possible CauseUCS005N H
Harness or connectors
[The PNP switch circuit is open or shorted.]
PNP switch
DTC Confirmation ProcedureUCS005NI
CAUTION:
Always drive vehicle at a safe speed.
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-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5
consecutive seconds.
VEHICLE SPEED: 10 km/h (6 MPH) or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
5. If the check result is NG, go to AT- 9 9 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
