CONSULT-II Function (A/T)
ECS00EFG
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).
