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 defines all regulatory emissions-related data elements of ISO/PAS 27145. A new
part may be added in the future upon availability of new legislated WWH-OBD GTR modules. The data
elements are used to provide the external test equipment with the diagnostic status of the emissions-related
system in the vehicle. All data elements are communicated with the unified diagnostic services as defined in
ISO/PAS 27145-3. Data elements are Diagnostic Trouble Codes (DTCs), Parameter Identifiers (PIDs),
Monitor Identifiers (MIDs), Test Identifiers (TIDs)/Routine Identifiers (RIDs) and InfoType Identifiers (ITIDs).
This part of ISO/PAS 27145 defines three (3) different sets of data elements:
a) A legacy (backward compatible) data set as defined in SAE J1939-71/-73 and ISO 15031-5/ISO 15031-6;
b) A unified data set (new data definition according to ISO/PAS 27145-2); and
c) A manufacturer data set (defined by manufacturer).
Each set of data elements uses its own scaling and encoding scheme. Legacy data elements are scaled and
encoded according the definitions in SAE J1939-71/-73 and ISO 15031-5/ISO 15031-6. Unified data elements
are scaled and encoded according to the definitions in ISO/PAS 27145-2. Manufacturer data elements are
recommended to be scaled and encoded according to the definitions of the unified data set. This will ease the
transfer of manufacturer defined data elements into the standardized (unified) data range.
