UDS ISO 14229 – Unified Diagnostic Service

Standardized CAN-based protocol for diagnostics

UDS (Unified Diagnostic Service) is based on the standards KWP2000 for K-Line and CAN. It was developed with the goal of standardizing different implementations of the predecessor standards and new requirements stemming from further developments in technology and new standards to form one generally valid diagnostic protocol. UDS describes the layer 7 protocol (diagnostic services) but is based on an extended version of the diagnostic protocol of KWP2000 on CAN (ISO 15765-2).

UDS is currently being launched in many areas of the automobile industry, but is also already in use in other industries.

Softing Experience

Softing played an active role in standardization from the very beginning, contributing its extensive communication expertise. As implementation and standardization ran concurrently, we have considerable experience that led to the implementation of the protocol for our diagnostic services.

In addition, we are familiar with the counterpart in detail thanks to our experience of implementing the diagnostic protocol in the ECU - a clear competitive edge.
