I don't know about net availability, but I believe that SAE HS-3000 
is the document that contains the collection of specs that make up 
OBDII.  Its about 200 pages and if I recall was fairly cheap from SAE 
(check out their web site).  I would email someone there for 
confirmation that it is what you want before purchasing though.  The 
preface mentions an effort by ISO to create a parallel spec, which 
leads me to think it won't be available at no cost (past experience) 
although you'd think since a gov agency is involved....

Looks like a lot of potential in OBDII for DYI'ers.
