On-Board Diagnostics in Vehicle Production

As modern vehicles become increasingly software-defined, the demands on diagnostics, commissioning, and system integration continue to grow throughout the entire vehicle lifecycle. DSA is expanding its portfolio with comprehensive onboard diagnostic functionality executed directly within the vehicle, enabling new opportunities for efficiency gains and automation.

In vehicle production, this technology enables commissioning functions to be executed fully onboard the vehicle. This includes all key commissioning operations such as configuration-dependent ECU flashing, coding and parameterization of functions, as well as verification and documentation of complete and correct commissioning. All diagnostic operations can be executed directly on high-performance controllers (HPCs) within the vehicle, reducing latency and minimizing dependencies on external infrastructure. The integration of external test systems, for example for wheel alignment adjustment, can also be controlled directly from within the vehicle.

Easy Integration into the Production System

Through integration into the DSA PRODIS Production System, a seamless and gradual transition to the onboard approach is possible. Mixed operation combining onboard and offboard diagnostics is also supported. In all cases, the PRODIS backend systems continue to provide data management, process control, and documentation.

A key advantage lies in its consistent usability throughout the entire vehicle lifecycle: components of the onboard diagnostics can remain within the vehicle and be seamlessly integrated into after-sales, workshop, remote, and Over-the-Air (OTA) processes as part of a unified diagnostic platform. To ensure smooth integration into existing system landscapes and provide long-term investment protection, the DSA solution is based on established diagnostic standards such as ODX, OTX, and SOVD.

The onboard approach reduces complexity, increases scalability, and establishes the foundation for automated and software-driven production and service processes.
