Unfortunately, there is no easy fix for these systems. I attached the basic warning messages and what they mean. Your message is the last in the list and it may be hard to see but it says to see dealer for service.
These tops have a series of micro switches that go in a series or progression and the control module needs to see each one complete its proper movement before it begins the next movement. In other words, the decklid needs to open prior to releasing the latches, and the latches need to release prior to moving the roof and so on. Basically, you don't want to just operate everything at once or just assume everything is working because if one component does not work then you will bind the top or worse yet, open the top onto the decklid and damage something.
The only way this can be figured out is to hook a scan tool to the vehicle and monitor each switch to find out which one is not functioning and then repair or adjust as needed.
These things are well known for being opened and someone still have golf clubs or obstructions in the trunk and the top collapses onto it and it bends the Z hinges and then nothing functions right.
Let me know if you have scan tool that can read the Power Top Control Module and I will send you the progression and we may be able to figure this out.
