I temporally gave up on Ford OBD2
seems to use initialization bits 
defined by the Ford Standard Corporate Protocol
documents ES-F7LC-12K529-BA and ....CA
Have not visited by local Ford dealer lately for jokes
VPW is similiar to rs485  rs422
from what i recall the recv. work great
but transmitters don't
rather sensitve to impeadance matching.

has some references, also rather helpful to
me when I first started in OBD2 if you 
have interest in there development systems
have not talked to them since 96

http://www.okisemi.com/communicator/public/nf/docs/Intro-7017.html
has a interface chip, schematics and general J1850 info.
some of there pdf  can end up as txt on your web page.
i think you also need a one time registration. 

Presently I have a rs232 to PWM PIC byte translator.
Have no Ford,  sometimes borrow a 96 snap-on to play with.
