Platform
How diagnostic sessions are structured and what each vehicle record contains.
KK Auto / automotive software
Diagnostics.
Data.
Vehicle history.
We develop tools for diagnostic sessions, vehicle control units, and service data management.

Software workspace
From diagnostic sessions to structured records.
Connect each diagnostic operation to a clear sequence, from the initial connection to the final report.
01
Diagnostic events
Connections, ECU scans, DTC readouts and service actions — all linked to one session.
02
System-to-system transfer
A data-exchange model connecting desktop diagnostics software with a server platform. Events, metadata and files can be handled separately.
03
Reports and history
Diagnostic results stay associated with the vehicle and remain available for future service work.
KK Diag
Tools built for the workshop.
The desktop application performs diagnostics at the workstation. The server-side system keeps results accessible beyond that single computer.
How data exchange works ↗- A session as the unit of work
One service visit, one vehicle and a traceable series of diagnostic actions.
- Events and attachments
Small events are transferred independently of large files and reports.
- Extensible integration
The proposed interface can support multiple workstations and independent file processing.
