the
following

There
are
two
main
groupings
of
faults
that
can
occur
in
the
control
processor.
The
first
grouping
of
faults
can
occur
during
the
GSA
unit
pre
‐
flight
test
(PFT).
If
there
is
a
fault
during
PFT,
the
unit
will
not
be
able
to
transition
to
normal
mode
and
the
only
way
to
clear
this
state
is
to
cycle
unit
power.
The
second
grouping
of
faults
can
occur
during
normal
mode.
These
faults
generally
cause
a
disconnect
of
power
to
the
GSA
and
report
that
a
fault
has
occurred
to
the
GIA.
The
notes
column
indicates
any
actions
that
can
be
taken
to
troubleshoot
the
problem
in
the
aircraft
by
the
technician.
Any
faults
that
are
not
listed
here
indicate
an
internal
problem
requiring
replacement
of
the
servo.
If
the
items
in
the
notes
column
check
out
ok,
replace
the
servo.
