This is a new one for me. After getting everything put back together after a HG job and then a misfire adventure everything is running smooth. I put my iCarSoft scanner on to verify everything was ok and found a DTC listed. It's also not showing any warning lights on the dash.
The code reads 'Permanent voltage supply fault'. I haven't had any electrical problems (so far). When its running my Ultraguage is showing voltage which looks acceptable (13.8-14.2).
The only thing I've been able to find with Google has been a confirmation that the ECM requires a permanent battery level voltage supply and a switched battery level voltage supply. It lists those as P0560, P0562 and P0563. However these don't seem to differentiate between permanent and switched.
