Emissions related to road vehicles between vehicles and external equipment

Communication of diagnostics - Part 2.Terms, definitions, abbreviations

and abbreviations guide

1 Scope

GB/T 42193.2-2022 is the vocabulary part of the seven-part GB/T 42193 series on communication between a road vehicle and external equipment for emissions-related diagnostics. It gives the terms, definitions, abbreviations and acronyms used across the series, explains how they are meant to be used, and lays down naming rules, including a procedure for constructing a new term so that later additions stay consistent with the ones already in circulation. A general information clause records the kinds of shop-floor usage that do not meet those rules, such as abbreviations that do not logically follow from the term and abbreviations formed at the level of a single morpheme, and a document overview clause maps the other parts of the series. Diagnostic communication fails on vocabulary more often than on protocol. A scan tool, an engine control unit and a service manual written by three different organisations have to mean the same thing by the same abbreviation, and the technician reading a fault description has to recognise it without a lookup table. When each supplier coins its own wording, the data is transmitted correctly and understood wrongly. Vehicle and control unit manufacturers, scan tool developers and technical writers preparing service documentation use it alongside the other parts, with terms drawn from ISO 15031-5 and ISO 15031-6.

This document gives the terms, definitions, abbreviations and guidelines for the use of acronyms for the communication of emission-related diagnostics between vehicles and external equipment;

A process for constructing new terminology is established. Since this document gives the recommended usage of diagnostic terms applicable to electrical/electronic systems, this document was compiled

Relevant mechanical terms, definitions, abbreviations and abbreviations are referenced throughout.

This document applies to all light-duty gasoline and diesel passenger cars, trucks, and heavy-duty gasoline vehicles. Specific applications of this document include diagnostic

Disconnects, Service and Repair Manuals, Bulletins and Updates, Training Manuals, Repair Database, Under Hood Emissions Labels and Emissions Certification Applications.

Interpretations of terms, abbreviations or abbreviations not contained in this document are also permitted.

This document is intended to assist the industry in providing standard terms, definitions, abbreviations, and abbreviations, with the goal of establishing common terminology for diagnostic tools and publications.

This document refers to SAEJ1930-DA, which includes all standard terms, definitions, abbreviations and abbreviations.

The terms and definitions defined in ISO 15031-5 and ISO 15031-6 apply to this document.

4 General information

Some commonly used terms understood by manufacturers and technicians may not strictly meet the requirements of this document, including the following three types of terms.

a) Abbreviations that do not logically fit the term.

b) Abbreviations at the morpheme level, that is, the term includes a further defined base word or noun used to describe common things.

c) Abbreviations that contain basic vocabulary items, but are often used as modifiers of other basic vocabulary. due to abbreviation one

is generally used as a modifier, and such use may be considered compliant.
