SAE J19394documents, on which parts of ISO 11783 are based

21、, were developed jointly for use in truck and bus applications and for construction and agriculture applications. Joint documents were completed to allow electronic units that meet the truck and bus SAE J1939 specifications to be used by agricultural and forestry equipment with minimal changes.Gener

22、al information on ISO 11783 is to be found in ISO 11783-1. The purpose of ISO 11783 is to provide an open, interconnected system for on-board electronic systems. It is intended to enable electronic control units (ECUs) to communicate with each other, providing a standardized system.The International

23、 Organization for Standardization (ISO) draws attention to the fact that it is claimed that compliance with this part of ISO 11783 can involve the use of a patent concerning the controller area network (CAN) protocol referred to throughout the document.ISO takes no position concerning the evidence,

24、validity, and scope of this patent.The holder of this patent has ensured ISO that he is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered wit

27、O 11783, as a whole, specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, semi-mounted, towed, or self-propelled implements. Its purpose is to standardize the method and format of transfer of data between sensors, actuators, control element

28、s and information storage, and display units, whether mounted on, or part of, the tractor or implement. This part of ISO 11783 describes the networks diagnostic system.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensabl

37、omplete network diagnostics and identify which unit has failed or is operating in a faulty state.6 Requirements6.1 ISO 11783 diagnosticsThis part of ISO 11783 specifies the diagnostics capabilities of control functions. The terms “level 0” and “level 1” diagnostics described in the 1st edition of th

38、is part of ISO 11783 are obsolete.Control function shall support all ISO 11783 diagnostic information messages defined in Annex B and their derived requirements. Parameters for these messages are defined in Annex A.An interface is required for an operator or service technician in order to diagnose p

39、roblems and faults on an ISO 11783 network. This diagnostic user interface can be provided by the virtual terminal or another type of user interface connected to the network. The information specified in the following subclauses shall be provided to the operator or service technician by this user in

40、terface for diagnosing problems and faults of the suspect connected ECU, sensor, or actuator.6.2 Network informationAll control functions connected to the ISO 11783 network shall provide network information to the diagnostic user interface. This information provides an overview of the status of all

41、communicating control functions connected to the operating network. It shall includea) the part number, serial number, and manufacturers name of the connected ECU containing control functions,2 ISO 2014 All rights reservedBS ISO 11783-12:2014ISO 11783-12:2014(E)b) the NAME of each control function a

42、s defined in ISO 11783-5,c) the version (or versions) of software and the versions of ECU-related software required by each control function,d) the compliance test data, including the laboratory that performed the test, certificate data, and year tested as provided by the test lab prior to the test,

43、 ande) the product identification message.The diagnostic user interface shall monitor the messages on the network to obtain information from the address claim process and shall request additional information from control functions. All CFs within the same ECU shall send the same ECU identification i

44、nformation. A typical network status screen is shown in Annex D.6.3 Network statisticsThe diagnostic user interface that displays the network status shall also use its network connection to measure the network bus statistics. At a minimum, the diagnostics user interface shall include the following n

45、etwork statistics if supported by hardware: bus load, CAN errors detected while sending or receiving messages, and network message count. If enabled by hardware, network statistics should also include average bus voltages averaged over a time period of 250 ms to 5 s.A typical screen of the network s

46、tatistics is presented in Annex D.6.4 Control function informationEach control function shall provide additional fault information to the diagnostics user interface. This information provides additional data to enable the operator or service technician to determine the problem or fault on a specific

47、 ECU. It includesa) the specific protocol of a control function required for non-ISO 11783 or ISO 11783 diagnostics,b) active diagnostic trouble codes (suspect parameter numbers and failure mode indicators),c) previously active diagnostic trouble codes (suspect parameter numbers and failure mode ind

48、icators), andd) fault occurrences (if available).Control functions shall also support clearing previously active diagnostic trouble codes (if required).The diagnostic user interface shall request the control functions suspect parameter number and fault mode indicator information using the messages s

49、pecified in Annex B. Parameters for these messages are defined in Annex A or in the appropriate part of ISO 11783. A typical screen of the above control function information is presented in Annex D. In addition, the user interface shall provide an equivalent screen of the network status. Annex E provides the definition of each failure mode indicator.6.5 FunctionalitiesEach control function shall provide its active functionality information to the diagnostics user interface.
