To clarify, the cpu that controls the top is a 991 unit not a 993. The 993 unit has special connection for the just for the parking brake.
to clarify the open and close position question. if the top is partially open it will move forward and backwards. With the top switches taped closed , as ECU recommends,the motors should function by opening and closing. The motors will only rotate one way, and that is closed.
The motors will work in both directions by bypassing the cpu and applying 12v as directed in the test plan. the motors open and close fine
with the tape removed and the top in the fully locked position the motors will not unlock.
a dilemma isn't it? something is telling the motors via the cpu not to unlock
