This SAE Recommended Practice defines an architecture, including operating modes, in which an advanced driver interface system and related software exist. It also provides reference to a set of Federal Highway Administration approved guidelines for human factors characteristics of such systems and related software.

This SAE Recommended Practice is applicable to all E/E systems on MD and HD vehicles. The terms defined are largely focused on compression-ignited and spark-ignited engines. Specific applications of this document include diagnostic, service and repair manuals, bulletins and updates, training manuals, repair data bases, under-hood emission labels, and emission certification applications. This document focuses on diagnostic terms, definitions, abbreviations, and acronyms applicable to E/E systems. It also covers mechanical systems which require definition. Nothing in this document should be construed as prohibiting the introduction of a term, abbreviation, or acronym not covered by this document. The use and appropriate updating of this document is strongly encouraged. Certain terms have already been in common use and are readily understood by manufacturers and technicians, but do not follow the methodology of this document.

The purpose of the SAE Information Report is to address the method of loading vehicle electronic controllers with chassis and customer specific parameters. This specification shall establish an interface definition. The interface definition must be mutually agreeable to truck OEMs and vendors. The purpose of this specification is not to answer the large protocol issues raised by systems such as GM’s MAP.
