CONSULT-II Function (A/T)UCS005N1
CONSULT-II can display each diagnostic item using the diagnostic test models shown following.
FUNCTION
CONSULT-II REFERENCE VALUE
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).

Diagnostic Procedure Without CONSULT-IIUCS005N2
TCM SELF-DIAGNOSTIC PROCEDURE
Description
If a malfunction occurs in electrical system, turning ignition switch ON will illuminate OD OFF indicator lamp for
2 seconds. To detect a malfunction, entering a self-diagnosis start signal retrieves information on malfunctions
from memory and indicates malfunction by blinking OD OFF indicator lamp.
Diagnostic Procedure
1. CHECK OD 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 OD OFF indicator lamp come on about 2 seconds?
YES >> GO TO 2.
NO >> Stop procedure. Perform AT-198, "
OD OFF Indicator
Lamp Does Not Come On" before proceeding.
2. JUDGEMENT PROCEDURE STEP 1
1. Turn ignition switch OFF.
2. Keep pressing shift lock release button.
3. Move selector lever from “P” to “D” position.
4. Turn ignition switch ON. (Do not start engine.)
5. Keep pressing overdrive control switch while OD OFF indicator lamp is lighting up for 2 seconds. (OD
OFF indicator lamp is on.)
6. Keep pressing overdrive control switch and shift selector lever to the “2” position. (OD OFF indicator lamp
is on.)
7. Stop pressing overdrive control switch. (OD OFF indicator lamp is on.)
8. Shift selector lever to the “1” position. (OD OFF indicator lamp is on.)
9. Keep pressing overdrive control switch. (OD OFF indicator lamp is off.)
10. Depress accelerator pedal fully while pressing overdrive control switch.
>> GO TO 3.

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" .
