So... I ran the tank dry and the battery too. Put in gas but car wouldn't start. Trying to jumpstart the 12v I pulled the orange fuse on the drive battery and didn't reinsert properly. Then I did the jumpstart but that error wouldn't let me start. I fixed the fuse but the error didn't go away for immediately so I towed it. Drove the car into the driveway and no error anymore. Turned car on and off several times and still no error.
