Network Management protocols are implemented in ECUs to provide a start-up of the network, node monitoring and to ensure that they go to a proper sleep mode when they don’t need the network, coordination among ECUs, support of diagnosis, reading and setting of network specific parameters and proper wake up of the network. OSEK/VDX based network management protocol is the most widely used among OEMs and its validation has proved to be of utmost importance these days. This paper is proposing a scalable validation framework using the model based architecture and relevant hardware to test the conformance of ECUs to the specifications of OSEK/VDX NM. OSEK/VDX works mainly via the exchange of network management CAN messages between the ECUs.

Unified Diagnostic Service and On Board Diagnostics require a client side device with necessary software to implement certain specific algorithms. This paper proposes a highly optimized and generic model based architecture to implement client side algorithms used in Unified Diagnostic Service systems and with On Board Diagnostics which can be reused for any hardware target. The proposed method can implement particular algorithms which include flow control, timing control, database parsing, logging of messages, diagnostic database parsing, security unlock, intuitive HMI layer, DTC display with textual information, frame control, multi network - multi ECU support, software flashing, physical-functional message handling, and interfacing for multiple hardware host devices. Re-usability of this model based product ensures that it can be ported to the diagnostic tool used by a work shop engineer or by a diagnostics validation engineer working at OEM or Tier 1suppliers.
