A quarter-century of aftermarket tools, one modern platform

Repair shops and mechanics are central to the commercial-vehicle business and will be so for years to come. The mechanic's role is growing more demanding, not less: as products become connected, the competence requirements rise — and the diagnostic tools have to keep pace. The most common diagnostic solutions are still local, technician-operated tools; the industry's direction is connected services and remote scenarios. The aftermarket platform has to serve both worlds at once.

Diadrom has been involved in central IT systems and aftermarket tools at Volvo Group since 1999, building a deep knowledge of the diagnostics domain across the Group. The centrepiece of the current work is the Aftermarket Tool — the application a workshop reaches for, in any market worldwide, to find out what is wrong with a vehicle and put it right.

The existing Aftermarket Tool is a 'fat' PC client: proven, but monolithic, and built for a local, workshop-only world. Volvo Group Digital & IT's goal is a modern, future-proof, modularised ecosystem — a service platform that can serve multiple end-user applications, handle both remote and workshop scenarios, and carry all the Group's brands on one foundation. The hard part is doing that while the world's Volvo workshops keep working every day.

Diadrom supports Volvo Group Digital & IT with a team of more than ten system developers, working in the core of the new service platform: unified diagnostic services, software download, and fault tracing & troubleshooting. It is the model Diadrom prefers — a long-term team inside the customer's process, carrying its diagnostics-domain knowledge of the Group into every design decision, rather than a one-off delivery thrown over a wall.

The aftermarket is where a vehicle spends almost all of its life, and the platform that diagnoses it decides how fast a workshop turns a fault into a fix. By modularising the toolchain, Volvo Group gets a foundation that serves today's workshop bay and tomorrow's remote scenario from the same diagnostics core — and Diadrom's quarter-century in the Group's diagnostics domain is what makes the migration a continuation rather than a restart.

The direction is set by the connected vehicle: more remote diagnostics, more over-the-air capability, and a growing share of fixes that begin before the vehicle reaches the workshop. The modular platform is built to absorb that shift — the same uptime logic that runs through everything Diadrom builds.
