标准简介：ISO/PAS 27145 is intended to become the single communication standard for access to OBD-related
information. To allow for a smooth migration from the existing communication standards to this future
worldwide standardized communication standard, the initial communication concept will be based on CAN. In
a second step, ISO/PAS 27145 will be extended to define the world-wide harmonized OBD communication
standard based on existing industry communications standards (e.g. Internet Protocol) over Ethernet. Due to
the usage of standard network layer protocols, future extensions to optional physical layers (e.g. wireless) are
possible.
This part of ISO/PAS 27145 specifies the implementation of a subset of unified diagnostic services (UDS) as
specified in ISO 14229-1. The diagnostic services are used to communicate all diagnostic data as defined in
ISO/PAS 27145-2.
The subset of unified diagnostic services derives from the requirements stated in the WWH-OBD GTR (World
Wide Harmonised Global Technical Regulations). The common message set defined in this part is
independent of the underlying Transport, Network, Data Link and Physical Layer. This document does not
specify any requirements for the in-vehicle network architecture.
This part of ISO/PAS 27145 includes a superset of a modified version of ISO 14229-1. Several significant
modifications are included in this part in order to support the data set of SAE J1939, ISO 15031-5 and
ISO 15031-6:
⎯ ISO/PAS 27145-3 supports a 3-byte Unified Data Identifier format in all services which support a 2-byte
data identifier format in the ISO 14229-1.
⎯ ISO/PAS 27145-3 supports a 4-byte Diagnostic Trouble Code format in all services which support a
3-byte Diagnostic Trouble Code format in the ISO 14229-1.
⎯ ISO/PAS 27145-3 supports a separation of BaseDTC number from a FailureTypeByte including the
symptom of the Diagnostic Trouble Code.
This part of ISO/PAS 27145 is designed to provide the basis of unified diagnostic services for future GTR
modules provided by legislation.
