CONSULT-II Function (A/T)ECS00FXA
CONSULT-II can display each diagnostic item using the diagnostic test modes 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. Display of solenoid valves on CONSULT-II changes at the start of shifting, while gear position is displayed
upon completion of shifting (which is computed by TCM).

CONSULT-II SETTING PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
lFor details, refer to the separate “CONSULT-II Operations Man-
ual”.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector, which is located in instrument lower panel on
driver side.
3. Turn ignition switch ON. (Do not start engine.)
4. Touch “START (NISSAN BASED VHCL)”.
5. Touch “A/T”.

Diagnostic Procedure Without CONSULT-IIECS00FXB
TCM SELF-DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-II)
Description
In the unlikely event of a malfunction in the electrical system, when the ignition switch is switched ON, the OD
OFF indicator lamp lights up for 2 seconds. If there is no malfunction, when the ignition switch is turned ON,
the indicator lamp lights up for 2 seconds. As a method for locating the suspect circuit, when the self-diagnos-
tics start signal is input, the memory for the malfunction location is output and OD OFF indicator lamp flashes
to display the corresponding DTC.
Diagnostic Procedure
1.CHECK OD OFF INDICATOR LAMP
1. Start the engine with selector lever in “P” position. Warm engine to normal operating temperature.
2. Turn ignition switch ON and OFF at least twice, then leave it in the OFF position.
3. Wait 10 seconds.
4. Turn ignition switch ON. (Do not start engine.)
Does OD OFF indicator lamp come on for about 2 seconds?
YES >> GO TO 2.
NO >> GO TOAT- 1 7 7 , "
OD OFF Indicator Lamp Does Not Come On".
2.JUDGEMENT PROCEDURE
1. Turn ignition switch OFF.
2. Keep pressing shift lock release button.
3. Move selector lever from “P” to “D” position.
4. Release accelerator pedal. (Set the closed throttle position signal ON.)
5. Depress brake pedal. (Stop lamp switch signal ON.)
6. Turn ignition switch ON.
7. Wait 3 seconds.
8. Move selector lever from “D” to “3” position.
9. Release brake pedal. (Stop lamp switch signal OFF.)
10. Move selector lever from “3” to “2” position.
11. Depress brake pedal. (Stop lamp switch signal ON.)
12. Release brake pedal. (Stop lamp switch signal OFF.)
13. Depress accelerator pedal fully and release it.
>> GO TO 3.
3.CHECK SELF-DIAGNOSIS CODE
Check OD OFF indicator lamp. Refer toAT-90, "
Judgement Self-diagnosis Code".
If the system does not go into self-diagnosis. Refer toAT-99, "
DTC P0705 PARK/NEUTRAL POSITION
SWITCH",AT- 1 6 8 , "CLOSED THROTTLE POSITION AND WIDE OPEN THROTTLE POSITION CIRCUIT",
AT- 1 6 9 , "

Judgement Self-diagnosis Code
If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.
Erase Self-diagnosis
lIn order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.
lHowever, this information is erased by turning ignition switch OFF after executing self-diagnosis or by
erasing the memory using the CONSULT-II.

DTC U1000 CAN COMMUNICATION LINEPFP:23710
DescriptionECS00FXC
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 LogicECS00FXD
Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-II or 17th judgement flicker without
CONSULT-II is detected when TCM cannot communicate to other control units.
Possible CauseECS00FXE
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureECS00FXF
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.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go toAT-93, "
Diagnostic Procedure".
WITHOUT CONSULT-II
1. Start engine and wait for at least 6 seconds.
2. Perform self-diagnosis. Refer toAT-89, "
Diagnostic Procedure Without CONSULT-II".
3. If DTC is detected, go toAT-93, "
