With top switch pressed "open":
- The CVM activates the latching drive motor, which releases and open the latches.
- The latch hall sensor confirms the release of the latches by sending a signal to the CVM.
- The CVM signals the GM to lower the windows (if closed) for approximately 1.5 second.
- The CVM activates the pump motor relay and the hydraulic pump pressurizes the hydraulic cylinders to pull the soft top open.
- The soft top will then be folded into the storage compartment.
- When the soft top is in the storage compartment, the top-down hall sensor signals the CVM to deactivate the hydraulic pump.
- The CVM will then activate the latching drive motor to "fold in" the latches.
