For now, let's think about what has to happen next for the top hydraulic motor to start running.

We have cleared the frame switch, the divider switch and top open switch. (Very good work, by the way, seldom does anyone actually get in there and measure!)

When you press the button, IF you are not going over 9mph, the TCM checks to see if it has an indication that the trunk lid is fully closed. If so, you should hear a faint sound as the TCM energizes an electric lock in the trunk, disabling it so no one can open the trunk while you are moving the top.

When the TCM gets the indication that the electric lock has locked, the motor should start.

I'm trying to think of ANYTHING that would stop it from activating the lock OTHER than speed over 9mph OR the lid not indicating fully closed.

Let me look to see how you can verify the lid indicating that it is closed....
