I have a tac 50-04 16 bit that intermittently gets stuck on phase one, have gotten it to clear by injecting fsh4 on group screen and toggling fsh5, however this time it would not come off phase one, the hall clears, but the car remains on phase one doors open, jewel lit. There is no secondary recall, so my question is.. Are fsh3, and fsh4 needed? And if I were to delete the i/o's in question could that solve my issue? Any input would be greatly appreciated.
