Vehicle Data Coverage — PID & DID Parameters
Search 66,137 deduplicated readable PID and DID parameters across 65 curated vehicle-brand groups and 48 standardized ECU families — the continuously expanded data foundation behind XENCHECK analytics, XENFLEET cause analysis and XENTRON AI.
Engineering overview
- 66,137 deduplicated readable PID and DID parameters.
- Per-brand parameter counts are published as exact figures at /vehicle-data/{brand} and /vehicle-data/index.json — e.g. Renault 9,700; Audi 3,671; Volkswagen 3,064; Ford 1,049.
- Each brand page lists the parameter names and their descriptions, not just the count; heavy vehicles, buses and machinery are covered separately in the J1939 catalogue.
- Parameter names are searchable per brand via /vehicle-data/brands/{slug}.json — e.g. Volkswagen publishes "Fuel level" under ECM, IPC and DATA, and TPMS signals under ABS/ESC.
- 65 curated vehicle-brand groups and 48 standardized ECU families.
- 2,269 alias and variant overlaps consolidated from 260 source module codes.
- Per-brand machine-readable JSON files for diagnostic-data discovery.
- XENCHECK Ultra can carry the complete published PID, DID and J1939 coverage catalogue securely in encrypted flash for local service-bay lookup.
