SP 5-810
From the flow chart on the previous slide, you
can see that a new SP (SP5-810-002) has been
added.
If you do this SP, the machine checks for the
fuse for new unit detection, and blows the fuse if
it is found.
If the fuse is not found and blown, the SP fails.
SP 5-810-002 is normally only done as part of the
countermeasure for SC 554.
Slide 181
SP5-810-1 does not look for or try to blow the fuse.
