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”.
If “A/T” is not indicated, go toGI-50, "
CONSULT-II Data Link
Connector (DLC) Circuit".
6. Perform each diagnostic test mode according to each service
procedure.

CONTROL VALVE WITH TCM REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery cable from the negative terminal.
2. Remove under cover.
3. Drain ATF through drain hole.
4. Remove control cable from A/T assembly. Refer toAT- 2 1 0 , "
COMPONENTS".
5. Disconnect A/T assembly harness connector.
6. Remove snap ring from A/T assembly harness connector.
7. Push A/T assembly harness connector.
CAUTION:
Be careful not to damage connector.
8. Remove oil pan and oil pan gasket.
9. Check foreign materials in oil pan to help determine cause of
malfunction. If the ATF is very dark, smell burned or contains
foreign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
lIf friction material is detected, replace radiator after repair
of A/T. Refer toCO-11, "
RADIATOR".
