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).

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 , "
BRAKE SIGNAL CIRCUIT".
