 Umm ISO standard 9141 is most certainly available from the American National Standards Institute.. ANSI..

 If you are trying to do OBD-II stuff over ISO-9141, the product already exists and is cheap..

 ISO-9141 and 9141/2 (aka 9141/CARB) are merely the base protocols for communication.. from there one of any one of 
 a number of "Keyword Protocols" developed by the OEM's are used.. and they are proprietary..

 Only the basic OBD-II stuff is "standard" and "available"
