    • description: The Sensor 2185 (KITAS 4.0) is second generation Tachograph Motion Sensor in the sense of Commission Implementing Regulation (EU) 2016/799, intended to be used in the digital tachograph system. The Digital Tachograph system additionally contains a vehicle unit, tachograph cards, an external GNSS (Global Navigation Satellite System) module (if applicable) and remote early detection communication readers. A motion sensor is installed within a road transport vehicle as part of a digital tachograph system. Its purpose is to provide a vehicle unit with motion data that accurately reflects the vehicle’s speed and distance traveled. The focus of this re-evaluation was on the one hand on the software changes and their impact on the security functionality of the TOE and on the other hand on the change of the housing seal.
