Just verified with KoneSpares that this unit is still available. They provided the following information:
The time limit is set to 25 years
The tool is not job specific
The tool is set to level 3 (supposedly the top level)
The tool will work on Montgomery/Kone Elevators and Escalators including E3000 and E5000. The only exception, is a specific controller type that has a service tool actually on board.

Price is $3865.00
