Autodata provides service schedules, diagnostic procedures, wiring diagrams, fault-tracing, component locations, maintenance specifications, and technical service bulletins for automobiles and light commercial vehicles. Point releases such as 3.46 generally focus on data additions, accuracy improvements, user-experience fixes, and compatibility or security patches. For workshops that depend on fast, reliable vehicle information, each incremental release can have practical operational impacts.

Before interactive wiring systems became standard, Autodata 3.46 offered high-quality, color-coded schematics. These diagrams were searchable by component (e.g., "ABS sensor" or "MAF sensor") and showed connector pinouts.

Autodata 3.46 is famous for its extensive electrical diagrams.

AutoData 3.46 is a version of the proprietary diagnostic database and vehicle specification system, widely used across Eastern European and Russian automotive service markets during the late 1990s and early 2000s. Unlike modern cloud-based platforms, AutoData 3.46 operates as a standalone, offline-capable knowledge base primarily focused on:

This version is notable for being one of the last releases before the transition to subscription-only models (AutoData 4.x and later). It represents a "golden era" of compact, functional automotive data distribution on CD-ROM.

The software includes oil reset procedures, service interval resets, and brake pad wear indicator resets. For many European cars that require complicated pedal sequences or scan tool commands, Autodata 3.46 provides the manual override steps.
