Proven diagnostics modules, lifted into the cloud

The rising importance of on- and off-board software for connected and autonomous vehicles changes where diagnostics happens. It is no longer only a workshop activity over a cable: it is a cloud service, reaching the vehicle over the internet, updating software over the air. The OEMs that move fastest are the ones that do not rebuild their diagnostics foundations to get there.

Lynk & Co develops connected mobility within the Geely family — vehicles where the digital service experience is as much the product as the car itself. New diagnostic services are part of that promise: knowing the state of the vehicle, tracing faults and delivering software wherever the car is.

Building cloud-based diagnostic services from scratch means re-solving problems that proven workshop diagnostics already solved: vehicle communication, unified diagnostic services, safe software delivery. The faster route is to reuse a verified core — if the supplier's product is engineered so its functionality can be licensed and lifted into a new context.

The engagement combines a Diadrom development team with a licence fee for the right to reuse functionality of Diadrom Diag Studio, developing new diagnostic services together with Lynk & Co. Concretely: Diag Studio software modules reused into the cloud; unified diagnostic services and diagnostics over internet protocol (DoIP); vehicle communication interface (VCI); and software over the air (SOTA). The services built on this core serve both Lynk & Co and Lotus, and the engagement continues today, with Diadrom maintaining them in production.

The Lynk & Co engagement proves the reuse model that defines Diadrom's product thinking: diagnostics functionality engineered once, verified hard, then licensed into new contexts — from workshop client to cloud service, and from one brand to two, with the same core now serving both Lynk & Co and Lotus. For the customer it compresses time-to-service; for the industry it shows that the connected car does not need a new diagnostics core, it needs a proven one with an API.

Software over the air and internet-protocol diagnostics are becoming the default delivery path for the software-defined vehicle. The module-reuse model scales with it — the same verified diagnostics core, surfacing wherever the vehicle's software lifecycle needs it.
