ISO 27145-1:2012 PDF

Scope: This part of ISO 27145 provides an overview of the structure and the partitioning of the different parts of allow for a smooth migration from the existing communication standards to this future world-wide communication standard, the initial communication concept is based on the ISO 15765 series, i.e. Diagnostic communication over Control Area Network (DoCAN). The intention is for the future communication concept to be based on the ISO 13400 series, i.e. Diagnostic communication over Internet Protocol (DoIP) utilizing Ethernet. In view of the usage of standard network layer protocols, future extensions to optional physical layers (e.g. wireless) are possible. standard. Based on the results of the initialization, the external test equipment determines which protocol and diagnostic services are supported by the vehicle’s emissions-related system, i.e. — legislated OBD: ISO 15031 series (based on DoCAN), and — legislated WWH-OBD: ISO 27145 series (based on DoCAN and DoIP).
