When opening and closing the convertible top I get the below "Check Control" message. It only happens about 60% of the time. The top operates fine even when the msg. is displayed. Has anyone else seen this? I had it in the shop and service did a number of voltage checks and said everything was fine. They couldn't duplicate the error and suggested I use a battery tender when car sits for a coupe of days. I had the tender on last night and this morning I got the same error. Any suggestions would be appreciated.
