Check all the micro switches for latches and trunk cover exc. If you have a enhanced scan tool it would make it much easier by looking at the pics for each switch.

Check for fluid leaks and correct amount of fluid in the reservoir. If all is good mechanically, then the problem is most likely with a broken wire or a microswitch. Most of the problems we see with roofs are from broken wires - they brake where they flex the most around hinges, Usually broken wires set fault codes but not always. Good luck.

There is a "calibration" procedure that needs done in order for the top to start working on its own. As long as there is truly no codes in the convertible top module present (as you stated). Also you must make sure that the hydraulic pressure is not in its "released" state. There is a cable that is under the rear seat that when pulled releases the pressure and lets the top be manually operated…
