Tac 32 goes down with an 1854. LU/LD stuck error. IMS shows a 1100 after, but that is just a shutdown fault -- the culprit is the 1854. Already changed the selector board. Was good for almost a year and right back to it. (had door issues in between but not related). It usually happens when oil is warm but does not go out on Oil Visc fault. Any suggestions. I assume it is a magnet problem / sensor / but we have tried to mitigate that already.
