Describes the implementation of a subset of unified diagnostic services (UDS) specified in ISO 14229-1.

This part of ISO27145 defines the implementation of a subset of unified diagnostic services (UDS) specified in ISO14229-1. The diagnostic services are used to communicate the diagnostic data defined in ISO27145-2.

The subset of unified diagnostic services derives from the requirements stated in the WWH-OBD GTR (Global technical regulation No. 5; see Reference [17]). The common message set defined in this part of ISO27145 is independent of the underlying transport, network, data link and physical layer. This part of ISO27145 does not specify any requirements for the in-vehicle network architecture.

This part of ISO27145 is compatible with ISO14229-1 and includes provisions to support the data set of SAE J1979-DA and SAE J2012-DA WWH-OBD.

This part of ISO27145 is intended for use with ISO27145-4, which is the entry point for the protocol initialization and is based on two different data links:

  • Diagnostic communication over Controller Area Network (DoCAN), ISO15765-1, ISO15765-2, ISO15765-4;

  • Diagnostic communication over Internet Protocol (DoIP), ISO13400 (all parts).

Due to the usage of standard network layer protocols, future extensions to optional physical layers (e.g. wireless) are possible.

Based on the results of the initialization, the external test equipment determines which protocol and diagnostic services are supported by the vehicle\'s emissions-related system, i.e.

  • legislated OBD: ISO15031 (all parts);

  • legislated WWH-OBD: ISO27145 (all parts).

This part of ISO27145 includes capabilities required to satisfy OBD regulations for multiple regions, vehicle types, model years, and engine types. Those regulations are not yet final for some regions and are expected to change in the future. This part of ISO27145 does not attempt to interpret the regulations and does not include applicability of the included diagnostic services and data parameters for various vehicle applications. It is intended that users of this part of ISO27145 verify the applicability of each of its clauses for a specific vehicle, engine, model year and region.
