CONSULT-II FUNCTION (A/T)
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 solenoid).
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 may differ slightly. This occurs because of the following reasons:
^ Actual shift schedule has more or less tolerance or allowance,
^ Shift schedule indicated refers to the point where shifts start, and
^ Gear position displayed on CONSULT-II indicates the point where shifts are completed.

Part 2:

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).

CONSULT-II SETTING PROCEDURE

CAUTION:
^ If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be detected in self-diagnosis depending on control unit which carry out CAN communication.
^ For details, refer to the separate CONSULT-II Operations Manual.
