I have a top that won't work, but I waited until I got my DRBIII emulator working on my Dell 8" tablet and did an analysis. I thought it would be more efficient to debug the behavior with the tool.
So, I figured how to rum the DRB III emulator and went through the convertible top section (sensors, modules etc). After manually cycling through roof opening and closing cycles and checking the position of the sensors, the only thing out of whack is the trunk closing lid is not showing closed. The DRB software lets you activate equipment and gives you the sensor status. It seems quite useful (if it helps fix a problem).

I took the trunk apart (several times) and checked all the wires and there does not seen to be anything obvious. From what I have seen in the forum posts is that there is a switch that is not well documented and it is in the same module as the electric door look. I verified that the previous owner had done the electric lock mod. There are two plugs going into that module. I am assuming one is the fire off the solenoid and maybe one is the sensor to say the trunk lid is closed. I am not sure what the sensor is measuring (the lock movement or what).

I am starting to look for a replacement, but I want to be sure this failure is probable. Back to the service manual and previous forum posts.

The only item i saw mentioned was putting pressure on the trunk and then trying to operate the roof and twisting the standoffs down that hold the lid off the the trunk.

Has there been any other trunk closed sensor failures?
