1. What is FMS? 

 

In 2002, six major truck manufacturers (Volvo, Scania, Iveco, MAN, DAF, Mercedes-Benz)  created a standardized vehicle interface which will be supported by these leading truck manufacturers for third parties access to get the vehicle data, called the FMS  (FLEET MANAGEMENT SYSTEM)standard. Since the establishment of the FMS standard, there's only one "language"- FMS protocol to learn the vehicle specific communication systems.

 

 

 

2. The FMS-interface

 

The FMS-interface is an optional interface of different truck manufacturers. Supported information is dependent upon vehicle equipment. For the full information set, additional Electronic Control Units (ECU) may be required.The FMS standard defines its own standard physical interface which is a 12pin coloured green and is located on the passenger side, behind the central electric unit in the instrument panel.  The appearance and interface definitions are as follows:
