See if this attachment will open for you.
I do not have the emmulator; I do have an actual DRB III.
I must start by selecting "DRB III STAND ALONE" and then go to the 1998 - 2007 diagnostic scan.
From there a screen comes up that will show the Crossfire card which is physically inserted into the base of the DRB III, and that card is used to scan the Crossfire systems.
Check the appendix D & F . They may help you get to the convertible top. My cars are all coupes so I have never had the need to find the info you are search for.

I have no idea how you would get there when using the emulator.
