Class B Data Communication Network Messages - Part 3 - Frame IDs for Single-Byte Forms of Headers
- Ground Vehicle Standard
Part 1 of SAE J2178 (Titled: Detailed Header Formats and Physical Address Assignments) describes the two allowed forms of message header formats, Single-Byte and Consolidated. It also contains the physical node address range assignments for the typical sub-systems of an automobile.
Part 2 of SAE J2178 (Titled: Data Parameter Definitions) defines the standard parametric data which may be exchanged on SAE J1850 (Class B) networks. The parameter scaling, ranges, and transfer functions are specified. Messages which refer to these parametric definitions shall always adhere to these parametric definitions. It is intended that at least one of the definitions for each parameter in this part match the SAE J1979 definition.
Part 3 of SAE J2178 (this part, Titled: Frame IDs for Single-Byte Forms of Headers) defines the message assignments for the Single-Byte header format and the one-byte form of the Consolidated header format.
Part 4 of SAE J2178 (Titled: Message Definition for Three-Byte Headers) defines the message assignments for the three-byte form of the Consolidated header format.

The ever-increasing consumer expectations of vehicle internal functions and connectivity to the environment are outstripping the capability of current data communication architecture design. To address this vulnerability this committee will investigate and endorse new vehicle architectures that meet system requirements such as: ¿ Reliability ¿ System design metrics ¿ Data security ¿ Fault Tolerance ¿ Built in testability ¿ Validation/Verification ¿ Compatibility ¿ Redundancy This committee¿s mission is the investigation and development of vehicle architecture and data communication protocols and methods required to achieve the growth expected in the area of vehicle electronics. The committee shall continue to contribute to the understanding and use of semiconductor devices such as microprocessors, power devices, and other integrated circuits and the data transmission media used in these systems. Thus, all vehicle architectures (excluding aircraft) and devices used in these systems shall be included. Specific objectives shall include: ¿ Address the effect of electrical power environments (e.g., 42V, ground offsets) ¿ Sponsor forums to evaluate new technologies (e.g., MOST, Bluetooth, Firewire) ¿ Publish technical reports on vehicle architecture and system partitioning, interfacing, modes of operation, protocol standards, recommended conformance test methods, and evaluation methods of those standards ¿ Maintain the existing documents relevant to this committee (e.g., glossary of automotive electronics terms, SAE J1213/1) ¿ Encourage the applicable industries, government and educational institutions to support the efforts of this committee.
