DANSK DS/ISO 27145-4 PDF

ISO 27145-4:2016 defines the requirements to successfully establish, maintain and terminate communication with a vehicle that implements the requirements of the WWH-OBD GTR (Global technical regulation No. 5; see Reference [16]). This requires plug and play communication capabilities for the vehicle, as well as for any test equipment that intends to establish communication with a vehicle. This part of ISO 27145 details all the OSI layer requirements to achieve this goal. ISO 27145-4:2016 is intended to become the single communication standard for access to information relating to vehicle on-board diagnostics (VOBD). To allow for a smooth migration from the existing communication standards to this future world-wide standardized communication standard, the communication concept as specified in this part of ISO 27145 is based on two different data links: - diagnostic communication over Controller Area Network (DoCAN), ISO 15765‑4; - diagnostic communication over Internet Protocol (DoIP), ISO 13400 (all parts). NOTE - It is intended that this part of ISO 27145 will be extended as necessary upon introduction of additional communication media. IMPORTANT ? Use cases deriving from country-specific implementation of GTR No. 5 into local legislation are not included in this part of ISO 27145.
