Functions of each hydraulic cylinder are as shown in the following table.






Electrical Parts In Hydraulic System
Retractable hard top control unit switches hydraulic pump rotation direction, hydraulic circuit by switching valve 1/2 ON or OFF, and extends or retracts each cylinder. Operation according to each parts state is as shown in the following table.

NOTE:
For the details of operation, refer to SEQUENCE OF HYDRAULIC SYSTEM.






SEQUENCE OF HYDRAULIC SYSTEM
There are 22 states in hydraulic system. Hydraulic system is controlled using combination of these 22 states and, at the same time, open and close operations of retractable hard top system are performed interlocking with other retractable hard top system components. (For interlock with other components, System Description)
Parts state (CONSULT-III display) according to sequential hydraulic system operations is as shown in the following table.
