This document specifies the technical requirements for several different trailers that may be incorporated into J1939-22 C-PG payloads to provide safety assurance data. Proper use of these trailers is suitable for meeting applicable functional safety standards for a given industry. This document provides enough details for trailers that another document (likely SAE J1939-22) can incorporate these details into specific trailer formats. Accordingly, this document does not define the Type of Service (TOS) or Trailer Format (TF) values to use for these trailers, nor does it define the position of these trailers relative to other trailers that provide security assurance data.

The purpose of this Recommended Practice is to verify that vehicles and/or components are capable of communicating a required set of information, in accordance with the diagnostic messages specified in SAE J1939-73, to fulfill the off-board diagnostic tool interface requirements contained in the government regulations cited below. This document describes the tests, methods, and results for verifying diagnostic communications from an off board diagnostic tool (i.e., scan tool) to a vehicle and/or component. SAE members have generated this document to serve as a guide for testing vehicles for compliance with ARB and other requirements for emissions-related on-board diagnostic (OBD) functions for heavy duty engines used in medium and heavy duty vehicles. The development of HD OBD regulations by US EPA and California’s Air Resources Board (ARB) require that diagnostic message services are exercised to evaluate diagnostic communication standardization requirements on production vehicles.

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 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.

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).

The purpose of these compliance procedures is to generate one or more test documents that outline the tests needed to assure that an ECU that is designed to operate as a node on a SAE J1939 network would do so correctly. SAE does not certify devices and these tests and their results do not constitute endorsement by SAE of any particular device. These tests are presented to allow testing of a Device to determine self-compliance by the manufacturer of a device. The manufacturer can use its record of what procedures were run successfully to show the level of compliance with SAE J1939.

This document will provide recommendations to vehicle manufacturers and component suppliers in securing the SAE J1939 network from the cybersecurity risks. It is recognized that not every application of SAE J1939 networks requires the same level of cyber security measures. The implement shall determine what security measures to implement at each level of the vehicle architecture.
