Road vehicles — Implementation of World-Wide Harmonized On-Board Diagnostics (WWH-OBD) communication requirements — Part 3: Common message dictionary

ISO 27145-3:2012 defines the implementation of a subset of unified diagnostic services (UDS) specified in ISO 14229-1. The diagnostic services are used to communicate the diagnostic data defined in ISO 27145-2. The subset of unified diagnostic services derives from the requirements stated in the World-Wide Harmonized On-Board Diagnostic Global Technical Regulations (WWH-OBD GTR). The common message set defined in ISO 27145-3:2012 is independent of the underlying transport, network, data link and physical layer. ISO 27145-3:2012 does not specify any requirements for the in-vehicle network architecture. ISO 27145-3:2012 is compatible with ISO 14229-1 and includes provisions to support the data set of SAE J1979-DA and SAE J2012-DA WWH-OBD. ISO 27145-3:2012 is intended for use with ISO 27145-4, which is the entry point for the protocol initialization and is based on two different data links: · Diagnostic communication over Controller Area Network (DoCAN), ISO 15765‑1, ISO 15765‑2, ISO 15765‑4; · Diagnostic communication over Internet Protocol (DoIP), ISO 13400 (all parts). ISO 27145-3:2012 includes capabilities required to satisfy OBD regulations for multiple regions, vehicle types, model years, and engine types. Those regulations are not yet final for some regions and are expected to change in the future. ISO 27145-3:2012 does not attempt to interpret the regulations and does not include applicability of the included diagnostic services and data parameters for various vehicle applications. It is intended that users of ISO 27145-3:2012 verify the applicability of each of its clauses for a specific vehicle, engine, model year and region.

Road vehicles — Implementation of World-Wide Harmonized On-Board Diagnostics (WWH-OBD) communication requirements — Part 4: Connection between vehicle and test equipment

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.

Road vehicles — Diagnostic communication over Internet Protocol (DoIP) — Part 4: Ethernet-based high-speed data link connector

ISO 13400-4:2016 specifies a minimum set of diagnostic Ethernet connector requirements which are based on ISO 15031‑3. The ISO 15031‑3 diagnostic connector is referenced by legislation in many countries. The diagnostic connection specified in this part of ISO 13400 consists of two mating connectors: the vehicle connector and the external test equipment connector as specified in ISO 15031‑3. ISO 13400-4:2016 specifies: - the functional requirements for the vehicle connector. These functional requirements are separated into two principal areas: connector contact allocation and electrical requirements for connector and related electrical circuits; - the functional requirements for the external test equipment connector. These functional requirements are separated into two principal areas: connector contact allocation and electrical requirements for connector and related electrical circuits. Two (2) different connector layouts and pin-outs are specified in this part of ISO 13400: a) Ethernet pin assignment option 1 (see Annex A); b) Ethernet pin assignment option 2 (see Annex B). Historically, option 1 is specified to meet Ethernet pin assignment of road vehicles already launched onto the market and may be used to resolve conflicts with vehicle manufacturer-specific usage of discretionary pins, e.g. pins 1 and 9. Option 2 is specified to meet the Ethernet pin assignment of road vehicles to resolve conflicts with vehicle manufacturer-specific usage of discretionary pins, e.g. pins 3 and 11. A discovery/identification and activation method of the vehicle's Ethernet via the "Ethernet Activation Line" is specified in ISO 13400‑3.

Road vehicles — Implementation of World-Wide Harmonized On-Board Diagnostics (WWH-OBD) communication requirements — Part 2: Common data dictionary

ISO 27145-2:2012 defines all regulatory data elements of the ISO 27145 series. The data elements are used to provide the external test equipment with the diagnostic status of the vehicle on-board diagnostics (VOBD) system in the vehicle. All data elements are communicated with the unified diagnostic services as defined in ISO 27145-3. The data elements are diagnostic trouble codes (DTCs), data identifiers (DIDs) and routine identifiers (RIDs). The mapping from parameter identifiers (PIDs), monitor identifiers (MIDs) and info type identifiers (ITIDs) is described in ISO 27145-2:2012. If new legislated WWH-OBD GTR modules are established, it is intended that ISO 27145 be applicable with possible extensions, which can be included in ISO 27145-2:2012, can be specified as enhancements of the SAE Digital Annexes or can even be part of other referenced documents which are intended to include the applicable data definitions. ISO 27145 is intended to become the single communication standard for access to OBD-related information (VOBD). To allow for a smooth migration from the existing communication standards to this future world-wide communication standard, the communication concept as specified in ISO 27145-4 is based on two different data links: ISO 15765-4 and ISO 13400 (all parts).

Road vehicles — Implementation of World-Wide Harmonized On-Board Diagnostics (WWH-OBD) communication requirements — Part 1: General information and use case definition

This part of ISO 27145 provides an overview of the structure and the partitioning of the different parts of ISO 27145 and shows the relationship between the parts. In addition, it outlines the use case scenarios where the ISO 27145 series is used. All terminology that is common throughout the ISO 27145 series is also outlined. ISO 27145 is intended to become the single communication standard for access to OBD-related information. To 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. ISO 27145 has been extended to define the world-wide harmonized On-Board Diagnostics (OBD) communication 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).
