I haven't looked at the manual for the pmt driver troubleshooting yet but i do have another crown i can change out parts to eliminate any possibilities. The 1 Rec seems to test good and the snubber filters are all good, unless it could be the block in between the two.
I've been doing this since 2014 and haven't had to change out anything in this SCR part of the truck besides one snubber one time and the guy that helped me said hes never had to change one in his career so they must be rare as well.

Any more advice is greatly appreciated, i'm definitely scratching my head.
