MOl 890 DIAGNOSTIC SECTIONS
MOl 890 allows you
to
select the
same
routines
as
used
in
the other MOls. In other words, routine PT03 in MOl
890
is
the
same
as
PT03 in MOl 800. However, the
routines in MOl 890 do
not
halt or branch when
sensing
a failing condition. The main advantage
of
MOl 890
is
that
it
allows you
to
select individual MOl sections which
is
especially useful when scoping intermittent failures.
