This document describes the application of the SAE J1939 recommended practices for compliance with on-board diagnostic malfunction detection system requirements for marine sterndrive and inboard spark ignition engines, as mandated by the California Air Resources Board (CARB). These Otto-cycle engines are not derived from automotive diesel-cycle engines.

This SAE Recommended Practice specifies the requirements for application of SAE J1939 in agricultural and forestry equipment. This document specifies the series of documents within the set of SAE J1939 documents that are applicable to agricultural and forestry equipment and provides further requirements for this industry. The SAE and ISO groups have cooperated to define agricultural and forestry networks in a manner to allow compatibility of ECUs and messaging protocols between agricultural and forestry ISO 11783 networks and truck and bus SAE J1939 networks.

This document describes the collection of IUMPR data required by the Heavy Duty On-Board Diagnostic regulation 13 CCR 1971.1 (l)(2.3.3), using SAE J1939-defined messages incorporated in a suite of software functions.

Define a process enabling devices to detect the baud rate of a network automatically with the intent of minimizing or eliminating communication disruption between existing devices.

Define a process enabling devices to detect the baud rate of a SAE J1939-11, SAE J1939-14, or SAE J1939-15 network automatically with the intent of minimizing or eliminating communication disruption between existing devices. These networks only support CBFF and CEFF Data Frames, as defined in ISO 11898-1.

SAE J1939-13 specifies the diagnostic connectors used for off-board connection to a vehicle’s SAE J1939 communication links. The defined diagnostic connectors support connection to the twisted shielded pair media (SAE J1939-11), the Reduced Physical Layer unshielded twisted pair (SAE J1939-15), the unshielded twisted pair of SAE J1939-14, as well as the twisted unshielded quad media (ISO 11783-2).

These SAE Recommended Practices are intended for light- and heavy-duty vehicles on- or off-road as well as appropriate stationary applications which use vehicle derived components (e.g., generator sets). Vehicle of interest include but are not limited to; on- and off-highway trucks and their trailers; construction equipment; and agricultural equipment and implements. The purpose of these documents is to provide an open interconnect system for electronic systems. It is the intention of these documents to allow electronic devices to communicate with each other by providing a standard architecture.
