In 1999, the truck manufacturer Scania introduced a FMS interface on their models as an accessory. This FMS interface was the first step in opening up engine management data from heavy vehicles. 2 years later on the Transport Logistics fair in Munich, the European truck brands agreed on supporting such a concept to open up vehicle data for the transport companies.

The truck brands Scania, Volvo, MAN, Mercedes Benz, DAF, Iveco and Renault favored this idea and some months later the first FMS implementations were released in their new truck models.
Nowadays FMS CANbus is available in the truck world, but still a few can benefit from it.
