23 - 456 CONVERTIBLE TOP
ZH
The Convertible Top operates by integrating both electrical/electronics and hydraulics to form the Power Top Control
System. The Power Top Control System is designed to function as a stand alone system.
Electrically, the Power Top Control Module (PTCM) is responsible for monitoring and controlling the functionality of
the hydraulic control system. The PTCM monitors various Travel Sensors, and Limit Switches throughout the Power
Top Control System to determine hydraulic fluid flow.
Hydraulically, the Power Top Hydraulic Assembly is a self contained unit. The Power Top Hydraulic Assembly
includes the motor, pump, and fluid reservoir. The Power Top Hydraulic Assembly operates the various hydraulic
cylinders and hydraulic latches that work to raise and lower the convertible top. The Power Top Hydraulic Assembly
operates directly from the outputs from the PTCM. The PTCM will activate the Rotational Relays, thereby energizing
the Pump Assembly.
