DESCRIPTION

BS ISO 14229-8:2020


This standard BS ISO 14229-8:2020 Road vehicles. Unified diagnostic services (UDS) is classified in these ICS categories:
  • 43.180 Diagnostic, maintenance and test equipment

This document specifies the implementation of a common set of unified diagnostic services (UDS) on clock extension peripheral interface networks in road vehicles. The UDSonCXPI diagnostics defines methods to implement diagnostic data transfer between a client and the CXPI slave nodes via the CXPI master node.

This document specifies support of three different diagnostic classes for CXPI slave nodes.

This document references ISO 14229-1 and ISO 14229-2 and specifies implementation requirements of the UDSonCXPI communication protocol for mainly HMI (Human Machine Interface), but not limited to, electric/electronic systems of road vehicles. UDSonCXPI defines how to implement the diagnostic data transfer between a client and CXPI slave nodes via CXPI master node.

NOTE

UDSonCXPI does not specify any requirement for the in-vehicle CXPI bus architecture.

This document refers to information contained in ISO 14229-1, ISO 14229-2 and ISO 20794 (all parts).

This document does not include any redundant information of the above-mentioned documents.

It focuses on

  • additional requirements specific to the implementation of UDSonCXPI network, and

  • specific restrictions in the implementation of UDSonCXPI network.
