The soft top and roll bar button lamps remaining on does not prevent you from retrieving codes. Try it. You should find you have at least one code stored in the controller.

As for the roll bar, you should retrieve the codes for that system. The associated socket on the diagnostic connector is #7.

If you do a search on Crew and roll bar, I think you will come across a thread where he describes problems he had which resulted from a faulty roll bar controller.
