From Vehicle Data to Service Decisions

A useful after-sales decision does not come from data volume alone. It comes from reliable acquisition, clear provenance and enough context for a technician to understand what the vehicle actually reported.

**One architecture, two sources of context**

XENTRON Ultra is the shared engineering core behind two purpose-built devices. XENCHECK Ultra supports the workshop by capturing diagnostic evidence from the vehicle. XENFLEET can add connected-vehicle context when it is installed, authorized and configured for that fleet. The two roles remain distinct even when their data is used in the same service process.

**Workshop evidence from XENCHECK Ultra**

The XENCHECK Ultra VCU communicates with supported vehicle networks through the DLC/OBD interface. Depending on the vehicle and enabled protocol coverage, it can capture the VIN, ECU inventory, DTCs, freeze-frame records and live values. Every item should retain its source, timestamp and acquisition context so later analysis can be traced back to the vehicle evidence.

**Connected context from XENFLEET**

Where XENFLEET is deployed and the customer has authorized the data flow, recent operating context can complement the workshop snapshot. This does not make telematics a substitute for a diagnostic test. It gives the technician another bounded source of evidence that may help explain when or under which conditions a symptom occurred.

**Enrichment without losing traceability**

Configured integrations may associate the technical record with available DMS, repair-order, campaign or parts information. Access depends on the customer's systems, APIs and permissions. Each added field must keep its source and freshness visible; missing context must remain missing rather than being inferred as fact.

**AI assists; the technician decides**

Rules and machine-learning models can group related signals, rank possible causes and highlight the next useful test. Their output is decision support, not an automatic diagnosis. A qualified technician validates the evidence, performs the required tests and approves the service action.

The right performance measures therefore cover the complete workflow: time to usable evidence, repeated data entry, incomplete records, traceability and the quality of technician-confirmed outcomes.
