Convertible Top: Description and Operation

The power top system allows the convertible top to be raised and lowered electrically by actuating a switch on the instrument panel. The power top system receives battery feed through a fuse in the Power Distribution Center (PDC), only when the ignition switch is in the ON position.

In each door there is a window regulator module directly connected to each of the front door window regulator motors. The window regulator module receives battery feed through a circuit breaker in the fuse block, only when the ignition switch is in the ON position. The modules control window motor operation and smart glass functions. The driver window module controls the convertible top operations by supplying a ground signal to the motor/hydraulic pump relay.

Power Top Components:

The main components of the power top system are:
- The power top framework and bows
- The motor/hydraulic pump assembly
- The power top well
- The power top pivot bracket
- The latch system
- The window regulator modules

The power top motor is part of the motor/hydraulic pump assembly and cannot be serviced separately. If the motor is inoperative the complete assembly must be replaced.

The power top switch is hard wired to both window regulator modules by the Power Top Switch Mux circuit. When a top operation input is received by the driver window regulator module, it will ground the respective relay control circuit which in turn will operate the power top motor. If the power top switch is pressed and held to the down position second detent, it will command both modules to drop all windows to the fully down position. The windows cannot be raised when the power top switch is in the top down position.

When the switch is held in the top up position and all four windows are fully up, the modules will lower the respective front window 40mm, lower the respective rear window for 0.52 seconds (approx. 55mm) and the driver window regulator module will ground the top up relay control circuit. Once the top is back up the windows will not raise automatically. When the top switch is pressed in either position, the driver window regulator module will ground the respective relay control circuit for a maximum of 30 seconds. The window regulator module monitors vehicle speed and if the speed is mover 15 mph. the top will not operate. for additional information on the window regulator module.
