s, the FMS standard is seen as a worldwide standard. A direct connection to the internal vehicle bus system is not permitted by the truck manufacturers and could lead to the loss of warranty. Meanwhile, some manufacturers are quite restrictive in their workshops and cut all unknown connections to the internal bus system. According to ACEA ca. 160,000 vehicles were fitted with an FMS standard interface in 2007. By 2019, more than 400,000 trucks use FMS in North America. The FMS-Standard was also the base for the Bus-FMS-Standard for buses and coaches which was published in the year 2004.
