In modern automotive engineering, on board diagnostics (OBD) plays a critical role in monitoring the behavior of components and subsystems through sensors and model-based detection techniques. Real-time OBD has become an essential part of vehicle software and electronics: it is mandated by legislation to ensure driver safety, emission compliance and vehicle performance.

When OBD is underestimated during development, the consequences can be significant: certification delays, costly field actions or, in the worst cases, recall campaigns. For this reason, early integration of on board diagnostics is key to ensuring compliance and avoiding late re-engineering costs.

With extensive experience in OBD development for Europe, the United States (including California), Asia Pacific and South America, and active participation in international bodies such as the SAE OBD Symposium, Dumarey is a trusted partner for global certification and advanced diagnostic solutions.
