CONSULT-IINJAT0022After performing ªSELF-DIAGNOSTIC PROCEDURE (WITH CON-
SULT-II)º (AT-37), place check marks for results on the ªDIAGNOS-
TIC WORKSHEETº, AT-69. Reference pages are provided follow-
ing the items.
NOTICE:
1) The CONSULT-II electrically displays shift timing and lock-up
timing (that is, operation timing of each solenoid).
Check for time difference between actual shift timing and the
CONSULT-II display. If the difference is noticeable, mechani-
cal parts (except solenoids, sensors, etc.) may be malfunction-
ing. Check mechanical parts using applicable diagnostic pro-
cedures.
2) Shift schedule (which implies gear position) displayed on
CONSULT-II and that indicated in Service Manual 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 ªAº or ªBº is displayed on CONSULT-II at
the start of shifting. Gear position is displayed upon completion
of shifting (which is computed by TCM).
4) Additional CONSULT-II information can be found in the Opera-
tion Manual supplied with the CONSULT-II unit.

SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)NJAT0022S021. Turn on CONSULT-II and touch ªA/Tº for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground
circuit. Refer to AT-116. If result is NG, refer to EL-10, ªPOWER
SUPPLY ROUTINGº.

Malfunction Indicator (MI)=NJAT02551. The malfunction indicator will light up when the ignition switch
is turned ON without the engine running. This is for checking
the lamp.
+If the malfunction indicator does not light up, refer to EL-107,
ªWarning Lampsº.
(Or see MI & CONSULT-II in EC section. Refer to EC-72,
ªDescriptionº, ªMalfunction Indicator (MI)º and EC-81, ªCON-
SULT-IIº.)
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has
detected an emission-related (EURO-OBD) malfunction. For
detail, refer to EC-57, ªON BOARD DIAGNOSTIC SYSTEM
DESCRIPTIONº.
