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.
