Road vehicles — Modular vehicle communication interface (MVCI) — Part 2: Diagnostic protocol data unit (D-PDU API)

This document specifies the diagnostic protocol data unit application programming interface (D‑PDU API) as a modular vehicle communication interface (MVCI) protocol module software interface and common basis for diagnostic and reprogramming software applications. This document covers the descriptions of the application programming interface (API) functions and the abstraction of diagnostic protocols, as well as the handling and description of MVCI protocol module features. Sample MVCI module description files accompany this document. The purpose of this document is to ensure that diagnostic and reprogramming applications from any vehicle or tool manufacturer can operate on a common software interface and can easily exchange MVCI protocol module implementations.

Road vehicles — Local Interconnect Network (LIN) — Part 3: Protocol specification

This document specifies the LIN protocol including the signal management, frame transfer, schedule table handling, task behaviour, status management, and commander and responder node. It contains also OSI layer 5 properties according to ISO 14229-7 UDSonLIN-based node configuration and identification services (SID: B016 to B816) belonging to the core protocol specification. A node (normally a commander node) that is connected to more than one LIN network is handled by higher layers (i.e. the application) not within the scope of this document.

Road vehicles — Local Interconnect Network (LIN) — Part 2: Transport protocol and network layer services

This document specifies a transport protocol and network layer services tailored to meet the requirements of LIN‑based vehicle network systems on local interconnect networks. The protocol specifies an unconfirmed communication. The LIN protocol supports the standardized service primitive interface as specified in ISO 14229-2. This document provides the transport protocol and network layer services to support different application layer implementations such as: — normal communication messages, and — diagnostic communication messages. The transport layer defines transportation of data that is contained in one or more frames. The transport layer messages are transported by diagnostic frames. A standardized API is specified for the transport layer. Use of the transport layer is targeting systems where diagnostics are performed on the backbone bus (e.g. CAN) and where the system builder wants to use the same diagnostic capabilities on the LIN sub-bus clusters. The messages are in fact identical to ones in ISO 15765-2 and the PDUs carrying the messages are very similar. The goals of the transport layer are: — to have low load on commander node, — to provide full (or a subset thereof) diagnostics directly on the responder nodes, and — to target clusters built with powerful LIN nodes (not the mainstream low cost).

Road vehicles — Local Interconnect Network (LIN) — Part 4: Electrical physical layer (EPL) specification 12 V/24 V

This document specifies the 12 V and 24 V electrical physical layers (EPL) of the LIN communications system. The electrical physical layer for LIN is designed for low-cost networks with bit rates up to 20 kbit/s to connect automotive electronic control units (ECUs). The medium that is used is a single wire for each receiver and transmitter with reference to ground. Annex A provides recommendations on the LIN physical layer peripheral interface design of type UART and frame controller for commander and responder nodes. This document includes the definition of electrical characteristics of the transmission itself and also the documentation of basic functionality for bus driver devices. This document also provides the physical layer definitions for nodes with LIN AA capabilities according to one of the procedures C, D and E. All parameters in this document are defined for the ambient temperature range from −40 °C to 125 °C.

Road vehicles — Local Interconnect Network (LIN) — Part 7: Electrical physical layer (EPL) conformance test specification

This document specifies the conformance test for the electrical physical layer (EPL) of the LIN communications system. The purpose of this document is to provide a standardised way to verify whether a LIN bus driver conforms to ISO 17987-4. The primary motivation is to ensure a level of interoperability of LIN bus drivers from different sources in a system environment. This document provides all the necessary technical information to ensure that test results are consistent even on different test systems, provided that the particular test suite and the test system are conformant to the content of this document.

Road vehicles — Open Test sequence eXchange format (OTX) — Part 4: Expanded extensions interface definition

This document defines the Open Test sequence eXchange (OTX) additional extension requirements and data model specifications. The requirements are derived from the use cases described in ISO 13209-1. They are listed in Clause 4. The data model specification aims at an exhaustive definition of all features of the OTX extensions which have been implemented to satisfy the requirements. This document establishes rules for the syntactical entities of each extension. Each of these syntactical entities is accompanied by semantic rules which determine how OTX documents containing extension features are interpreted. The syntax rules are provided by UML[2] class diagrams and XML schemas, whereas the semantics are given by UML activity diagrams and prose definitions.

Road vehicles — Controller area network (CAN) — Part 1: Data link layer and physical coding sublayer

This document specifies the controller area network (CAN) data link layer (DLL) and the physical coding sub-layer (PCS). The CAN DLL features data fields of up to 2048 byte when the CAN extended data field length (XL) frame format is used. This document divides the CAN DLL into the logical link control (LLC) and the medium access control (MAC) sub-layers. The DLL’s service data unit (SDU), which interfaces the LLC and the MAC, is implemented by means of the LLC frame. The LLC frame also features the service data unit type (SDT) and the virtual CAN channel identifier (VCID), which provide higher-layer protocol configuration and identification information. How the higher-layer functions are handled is not specified in this document. There are five implementation options: 1) support of the CAN classic frame format only, not tolerating the CAN flexible data rate (FD) frame format; 2) support of the CAN classic frame format and tolerating the CAN FD frame format; 3) support of the CAN classic frame format and the CAN FD frame format; 4) support of the CAN classic frame format, the CAN FD frame format and the CAN XL frame format; 5) support of the CAN FD frame format for CAN FD light responders (Annex A). NOTE Nodes of the first option can communicate with nodes of the third and fourth option when only the CAN classic frame format is used. Nodes of the first option cannot communicate with nodes of the fifth option: any attempt at communication generates error frames. Therefore, new designs implementing the fourth option can communicate with all other nodes.

Road vehicles — Diagnostic communication over Controller Area Network (DoCAN) — Part 2: Transport protocol and network layer services

This document specifies a transport and network layer protocol with transport and network layer services tailored to meet the requirements of CAN-based vehicle network systems on controller area networks as specified in ISO 11898-1. The diagnostic communication over controller area network (DoCAN) protocol supports the standardized abstract service primitive interface as specified in ISO 14229-2 (UDS). This document supports different application layer protocols such as: — enhanced vehicle diagnostics (emissions-related system diagnostics beyond legislated functionality, non-emissions-related system diagnostics); — emissions-related on-board diagnostics (OBD) as specified in the ISO 15031 series and SAE J1979 series; — world-wide harmonized on-board diagnostics (WWH-OBD) as specified in the ISO 27145 series; and — end of life activation of on-board pyrotechnic devices (the ISO 26021 series). The transport protocol specifies an unconfirmed communication. NOTE This document does not determine whether CAN CC, CAN FD or both are recommended or required to be implemented by other standards referencing this document.
