Malfunction Indicator Lamp (MIL)NCS0001Y
DESCRIPTION
The MIL is located on the instrument panel.
1. The MIL will light up when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
If the MIL does not light up, refer to DI-56, "WARNING LAMPS" ,
or see EC-716, "
MIL AND DATA LINK CONNECTOR" .
2. When the engine is started, the MIL should go off.
If the MIL remains on, the on board diagnostic system has
detected an engine system malfunction.

Decelerate by pressing lightly on the brake pedal.
With CONSULT-III
Read the gear position and engine speed. AT- 8 8 , "
DATA MONITOR MODE" .
When the A/T shift
-down D5 → D4 , does the engine speed drop smoothly back to idle?

CONSULT-III Function (TRANSMISSION)NCS0002E
CONSULT-III can display each diagnostic item using the diagnostic test mode shown following.
FUNCTION
CONSULT-III REFERENCE VALUE
NOTICE:
1. The CONSULT-III 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-III 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-III 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-III indicates the point where shifts are completed.
3. Display of solenoid valves on CONSULT-III changes at the start of shifting, while gear position is dis-
played upon completion of shifting (which is computed by TCM).
Diagnostic test mode Function
Work supportThis mode enables a technician to adjust some devices faster and more accurately by following the
indications on CONSULT-III.
Self-diagnostic results Self-diagnostic results can be read and erased quickly.
Data monitor Input/Output data in the ECU can be read.
CAN diagnostic support monitor The results of transmit/receive diagnosis of CAN communication can be read.
Function testPerformed by CONSULT-III instead of a technician to determine whether each system is “OK” or
“NG”.
DTC work support Select the operating condition to confirm Diagnosis Trouble Codes.
ECU part number TCM part number can be read.

TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
Diagnostic Procedure Without CONSULT-IIINCS0002F
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-125, "Generic Scan Tool (GST) Function" .
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-62, "Malfunction Indicator Lamp (MIL)" .
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
When the ignition switch is turned ON, the indicator lamp lights up 2 seconds. 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 A/T CHECK indicator lamp flashes to display the corresponding DTC.
Diagnostic 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- 1 7 2 , "
A/T Check Indicator Lamp Does Not Come On" .
2. JUDGMENT 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. (Do not start engine.)
7. Wait 3 seconds.
8. Move the selector lever to the manual shift gate side. (Manual mode switch ON.)
9. Release brake pedal. (Stop lamp switch signal OFF.)
10. Move the selector lever to “D” position. (Manual mode switch 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- 9 3 , "
Judgment Self-diagnosis Code" .
If the system does not go into self-diagnostics. Refer to AT- 1 0 2 , "
DTC P0705 PARK/NEUTRAL POSITION
SWITCH" , AT- 1 5 7 , "DTC P1815 MANUAL MODE SWITCH" , AT- 1 6 6 , "CLOSED THROTTLE POSITION AND
WIDE OPEN THROTTLE POSITION CIRCUIT" , AT- 1 6 7 , "BRAKE SIGNAL CIRCUIT" .
