I was looking at a 1996 C-3500 vortec a few years ago, it used 10.4 
KB VPW J2190.  The truck was labeled OBD-2 but did not support
mandated J1979 so is a problem decoding the packed stream, thou
could be easier if using same byte stream as ALDL and you know those 
codes.  I did establish connection using mode $2A but found other GM 
cars required $2C which defined by manufactuer.
All american cars that do not comply with J1979 or a problem.
