From the 28th to the 30th of January 2026, DSA presented innovative solutions for diagnosing software-defined vehicle architectures at SIAT India in Pune. The international trade fair is known as the leading platform for technologies related to vehicle development, testing and validation.
The focus of DSA’s presence was on the end-to-end toolchain covering the entire vehicle life cycle – from engineering to production and after-sales to connected vehicle scenarios. Many visitors took the opportunity to learn about the current requirements and challenges of modern diagnostic tools in the field of software-defined vehicles (SDVs). The lively interest shown by visitors at the DSA booth underscored the relevance of integrated, end-to-end diagnostic solutions for software-defined vehicle architectures.
Diagnostic and hardware solutions throughout the vehicle life cycle
DSA's engineering solutions support the development of software-defined vehicles right from the early project phase. At SIAT India, DSA showcased how software-based functions, services and their dependencies can be analysed transparently using the ODX front-loading tester PRODIS.OFT. This allows cause-and-effect chains to be identified at an early stage.
In addition, DSA presented the Diagnostic Data Platform PRODIS.DDP, a central platform for the consistent management of diagnostic and communication data across different development and application areas. The Vehicle Diagnostic Simulation PRODIS.VDS illustrated how diagnostic concepts and processes can be efficiently validated and secured even before series production.
On this basis, DSA showed how engineering results can be transferred to production and after-sales without media discontinuities. The presented DSA tester hardware portfolio comprises flexible, scalable devices for a wide range of diagnostic applications – from engineering setups and production environments to service and remote diagnostic scenarios in the field.
Expert presentation: Monitoring and diagnosing software-defined vehicles
Another key topic was the conference presentation ‘Monitoring and Diagnosing Software-Defined Vehicle Architectures’ by Dr Boris Böhlen. The presentation addressed the limitations of traditional UDS-based diagnostic approaches and showed how the ASAM SOVD (ISO 17978) standard extends the diagnosis of software-defined vehicles. These include standardised access to log data, extended service monitoring and holistic root cause analysis across distributed systems, including vehicle and cloud components.
Many of the questions discussed following the presentation on typical challenges in diagnosing SDVs and integrating them into existing vehicle architectures were reflected in the intensive expert discussions at the DSA stand.
