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" .

Judgment Self-diagnosis Code
If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.
Erase Self-diagnosis

In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.

However, this information is erased by turning ignition switch OFF after performing self-diagnostics or by
erasing the memory using the CONSULT-III.

DTC U1000 CAN COMMUNICATION LINE
Revision: 2006 November2007 350Z
DTC U1000 CAN COMMUNICATION LINEPFP:23710
DescriptionNCS0002G
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicNCS0002H

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-III or 17th judgment flicker without
CONSULT-III is detected when TCM cannot communicate to other control units.
Possible CauseNCS0002I
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureNCS0002J
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “ECU INPUT SIGNALS” or “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION”
with CONSULT-III.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go to AT- 9 6 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.

TCM terminals and data are reference value. Measured between each terminal and ground.
Diagnostic ProcedureNCS0002L
1. CHECK CAN COMMUNICATION CIRCUIT
With CONSULT-III
1. Turn ignition switch ON and start engine.
2. Select “SELF-DIAG RESULTS” mode for “TRANSMISSION” with CONSULT-III.
Is any malfunction of the
“CAN COMM CIRCUIT” indicated?
YES >> Print out CONSULT-III screen, GO TO LAN section. Refer to LAN-48, "CAN System Specification
Chart" .
