TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
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.
