If the header is $(top_srcdir)/subdir/Action.h, you have two possibilities:

a) either use
        #include <subdir/Action.h>
and
        INCLUDES = $(top_srcdir)

b) or use
        #include <Action.h>
and add
        INCLUDES = $(top_srcdir)/subdir

It seems you prefer the latter, so you need:
        INCLUDES = $(top_srcdir)/src


Two more comments:
1)  INCLUDES is considered obsolete, you should use AM_CPPFLAGS.
But you also use test001_CPPFLAGS, so you need to replace these two lines:

> INCLUDES = -I$(top_builddir) -I$(top_srcdir)
> test001_CPPFLAGS = -Da_p=a_confirm

with 

  AM_CPPFLAGS = -I$(top_srcdir)/src
  test001_CPPFLAGS = $(AM_CPPFLAGS) -Da_p=a_confirm

For a detailed explanation, see

2)
It was pure luck that the non-VPATH build worked. (I won't go into details.)
If you want to use headers from other subdirs, you have to add
        $(top_srcdir)/subdir/subsubdir
to AM_CPPFLAGS.

HTH,
