I am looking at obd-2 data, some of the J2190 packet data could be 
similiar. I have made vehicle units to hook into scan tool to 
decode.  Have been looking at a 96 C-3500 which also sends out 8192.
I am still sorting thru the 1792 possible obd-2  J1979 open std 
messages.  I will work on ALDL and KWP2000 next and glad to help.
