TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
CONSULT-II Function (A/T)NCS001KH
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-IINCS001KI
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-146, "Generic Scan Tool (GST) Function" (for VQ35DE engine), EC-859, "Generic Scan Tool
(GST) Function" (for VK45DE engine).
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-69, "Malfunction Indicator Lamp (MIL)" (for VQ35DE engine), EC-780, "Malfunction Indicator
Lamp (MIL)" (for VK45DE engine).
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
As a method for locating the suspect circuit, when the self-diagnostics start signal is input, the memory for the
malfunction location is output and the A/T CHECK indicator lamp flashes to display the corresponding DTC.
Operation Procedure
1. CHECK A/T CHECK 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 A/T CHECK indicator lamp come on for about 2 seconds?
YES >> GO TO 2.
NO >> GO TO AT-190, "
A/T CHECK 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 the selector lever to the manual shift gate side. (Manual mode signal ON.)
9. Release brake pedal. (Stop lamp switch signal OFF.)
10. Move the selector lever to “D” position. (Manual mode signal OFF.)
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 A/T CHECK indicator lamp.
Refer to AT-104, "
Judgement Self-diagnosis Code" .
If the system does not go into self-diagnostics. Refer to AT- 11 3 , "
DTC P0705 PARK/NEUTRAL POSITION
SWITCH" , AT- 1 8 4 , "CLOSED THROTTLE POSITION AND WIDE OPEN THROTTLE POSITION CIRCUIT" ,
