aloha.crossfire,

Have you checked the fluid level in the pump? The pump is in the left rear of the trunk.

The RST controller (roadster soft top controller) gets readouts from the micro switches in all the various positions of the top. When you put up the top, the storage cover aka tonneau cover will latch first behind your seats. When that step is completed, the controller gets a signal that the lock is closed and it lets the rear bow (rear window portion) go down. There should be a signal coming from one of the bow tension cylinders that the rear bow is down and thus pressurizing the rear bow lock cylinder to latch as soon as the prong enters the rear bow latch. The rear bow latch is designed such that the cylinder cannot close it without the rear bow prong being in it.

When the rear bow is down, just before you push on it, is the pump still running? After you pushed on it lightly and you hear a beeping because the cycle isn't complete, is the pump still running?

To get rid of the beeping, until you find the cause for the malfunction, you can lock the rear bow latch manually with a 6mm Allen wrench. The lock is accessible from the trunk. Turn counter-clockwise to lock.
