You can buy a UIT which mounts ontop of the CPUA. You will be able to reset faults ( like the tfr ) and view faults etc. You can actually fully adjust a tac50 tru this interface. Other then the UIT, IMS is required. POR ( Power off reset's) don't clear these sort of errors and so they shouldn't in my opinion.
Oh and btw the IMS tool is not limited at all you must have "Owners" version.
