Foreword
This Document was drafted as per the rules specified in GB/T 1.1-2020 Directives for
Standardization – Part 1: Rules for the Structure and Drafting of Standardizing Documents.
This Document was Part 3 of GB/T 41590 Road Vehicles – Diagnostic Communication over K-
Line (DoK-Line). GB/T 41590 has published the following parts:
--- Part 1: Physical Layer;
--- Part 2: Data Link Layer;
--- Part 3: Application Layer;
--- Part 4: Requirements for Emission-Related Systems.
This Document equivalently adopts ISO 14230-3:1999 Road Vehicles – Diagnostic Systems –
Keyword Protocol 2000 – Part 3: Application Layer.
This Document made the following minimum editorial modifications:
--- In order to coordinate with the existing standard, change the standard name into Road
Vehicles – Diagnostic Communication over K-Line (DoK-Line) – Part 3: Application
Layer.
--- In order to meet the requirements of GB/T 1.1-2020, the numbers of footnotes in Tables
are changed from numbers to letters;
--- Slight adjust the parameter formats in Table 89;
--- Make corrigendum to 10.6.3 of ISO 14230-3:1999.

Road Vehicles – Diagnostic Communication
over K-Line (DoK-Line) – Part 3: Application Layer
1 Scope
This Document specifies the requirements for K-Line-based diagnostic communication data
link on which one or several on-vehicle Electronic Control Units are connected to an off-board
tester in order to perform diagnostic functions.
This Document specifies the requirements of the implementation of the Diagnostic Services
specified in ISO 14229, including
--- byte-encoding and hexadecimal values for the service identifiers;
--- byte-encoding for the parameters of the diagnostic service requests and responses;
--- hexadecimal values for the standard parameters.
The vehicle environment to which this Document applies may consist of a single tester that
may be temporarily connected to the on-vehicle diagnostic data link and several on-vehicle
Electronic Control Units connected directly or indirectly (see Figure 2).

4 Conventions
4.1 General
4.1.1 This Document is guided by the OSI service conventions (CVT; see ISO 10731) to the
extent that they are applicable to the diagnostic services. These conventions define the
interactions between the service use and the service provider by the supplier through service
primitives which themselves may convey parameters.
4.1.2 Table 1 indicates the different ranges of service identifier values, which are defined in
SAE J 1979, ISO 14230 or by the vehicle manufacturer.
