TROUBLE DIAGNOSIS

CONSULT-II Function (A/T)

NCS000C6

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).
