Diagnostik-, underhålls- och provningsutrustningar

This document specifies data link independent requirements of diagnostic services, which allow a diagnostic tester (client) to control diagnostic functions in an on-vehicle electronic control unit (ECU, server) such as an electronic fuel injection, automatic gearbox, anti-lock braking system, etc. connected to a serial data link embedded in a road vehicle.

It specifies generic services, which allow the diagnostic tester (client) to stop or to resume non-diagnostic message transmission on the data link.

This document does not apply to non-diagnostic message transmission on the vehicle's communication data link between two electronic control units. However, this document does not restrict an in-vehicle on-board tester (client) implementation in an ECU in order to utilize the diagnostic services on the vehicle's communication data link to perform bidirectional diagnostic data exchange.

This document does not specify any implementation requirements.

ISO/SAE 1979-3 is intended to satisfy the data reporting requirements of regulations in the United States and Europe, and any other market that may adopt similar requirements in the future. This document specifies diagnostic services required to be supported by motor vehicles and external test equipment for diagnostic purposes which pertain to Zero Emission Vehicle (ZEV) propulsion related data. These messages are intended to be used by any external test equipment for retrieval of OBD information from a vehicle. This document specifies: 1. message formats for request and response messages, 2. application and session timing requirements between request messages from external test equipment and response messages from vehicles, and between those messages and subsequent request messages, 3. behavior of both, the vehicle and external test equipment if data is not available, 4. a set of diagnostic services, with corresponding content of request and response messages, and 5. standardized source and target addresses for external test equipment and vehicle. This document includes capabilities required to satisfy OBD requirements for multiple regions, model years, engine types, and vehicle types. At the time of publication many regional regulations are not yet final and are expected to change in the future. This document makes no attempt to interpret the regulations and does not include applicability of the included diagnostic services and data parameters for various vehicle applications. The user of this document is responsible to verify the applicability of each section of this document for a specific vehicle, propulsion system, model year, and region. This document provides an implementation guidance based on the principles of ISO 14229 series, focusing on standardization of data to ensure access to important repair information by independent repair facilities. The purpose of this standard is to focus on providing the necessary content and performance requirements. ISO/SAE 1979-3 specifies diagnostic functionalities, which utilize communication facilities over either Controller Area Network (CAN) or Ethernet data links. These requirements apply to all ECU’s that provide operational data and diagnose those components that are integral to provide propulsion on a Zero Emission Vehicle (ZEV). In general, if an ECU monitors a component, whose failure directly affects the ZEV propulsion system, the information reporting uses the diagnostic communication services as specified in ISO/SAE 1979-3. A government agency may have policy reasons for specifically tracking ZEV componentry (i.e., unique warranty requirements). In order to track the linkage between a diagnostic trouble code and a covered repair under a ZEV component warranty, provisions are made in ISO/SAE 1979-3 to highlight those failures that are ZEV propulsion related. These linkages can be thought of analogously to emissions-related failures requiring emissions-related warranty repair. Note: When referencing other documents to fulfil this set of requirements, the reader should substitute “emissions-related” for “ZEV propulsion". Global regulations may vary in the definition of ZEV propulsion componentry, therefore the applicability of ISO/SAE 1979-3 to various components may vary from region to region.

This document contains technical safety requirements for the design, equipment and testing of brushless vehicle washing systems and vehicle washing systems with brushes for, indoor and outdoor operation, i.e. roll-over vehicle washing systems, vehicle washing tunnels, manually movable vehicle washing facilities. NOTE 1 Annex D covers the determination and control of Legionella and Pseudomonas aeruginosa concentration in stationary vehicle wash systems. Additionally, it can be applied to all vehicle washing systems that can form aerosols due to their cleaning systems. This document does not apply to hand-guided high pressure cleaners which are covered by EN 60335 2-79:2012, to water recycling systems, buildings and doors for entering the traffic zone, for powered ride-on machines and powered walk-behind machines with a traction drive. This document does not apply to bicycle cleaning systems. NOTE 2 Signals (example doors, lighting systems) can be provided by the vehicle washing system. This document contains requirements for the protection of persons and objects from accidents and damages during use and operation of vehicle washing systems. Persons to be protected are: - operators, - maintenance and monitoring personnel, - persons in the vicinity of vehicle washing systems, - persons sitting in the vehicle during cleaning. Objects to be protected are: - vehicles. Significant hazards associated with vehicle washing systems are listed in Clause 4. These hazards have been established by a risk assessment according to EN ISO 12100 and require measures to eliminate the hazard or to reduce the risk. These measures are specified in Clause 5 of this document. The safety requirements assume that vehicle washing systems are regularly maintained by trained and competent persons according to the manufacturer's information and that the operators, with the exception of users of self-service washing systems, have been instructed in the handling of vehicle washing systems.
