Diagnostic Services


Buses, vans or trucks, as the heavyweights on the roads, need a professional inspection just like the cars. Our developments in vehicle diagnostics support the reading of fault codes and programming of ECUs. We are familiar with the wear and service data, as well as the parameterization of the control units in detail.

Unlocking functions, resetting error codes or other entries in the ECUs are aspects of our daily tasks.

In doing so, we develop and support a wide variety of fault diagnoses and system settings relating to important technical properties and comfort functions.

  • We develop diagnostic solutions for all sectors, from VANs to heavy trucks.
  • Do you work with industrial units, cranes or construction machinery? No problem, we also offer the professional diagnostic solution for this.
  • We support you in server- and platform-based production systems, e.g. in the residual bus simulation of individual ECUs, or in the validation of the online platforms of fleet management.
  • Supplying ECUs with the latest firmware is also one of our tasks, cyclically preparing data packages and making them available to OEM distribution channels.
