Update on the inoperative convertible top on my 05 Roadster. With the help provided here I've been picking though what seems like 2 separate issues. Found the trunk lock circuit not operating properly so I acquired a trunk lock and replaced the bad one. The top now has no flashing lights with the car running. When I close or open the roof manually I am able to get a completed "beep" when I hold the switch down for a moment but it still will not operate either up or down. I'll keep working on each item in the sequence of events until I locate the culprit.
Question is will any other scanner read DTC's in the PTCM besides the DRB3?
Thanks again!!
