Jaguar's factory diagnostic platforms include WDS, Jaguar Land Rover IDS, Symptom Driven Diagnostics, Pathfinder and TOPIx Cloud Diagnostics, with coverage depending on model, year and system. See the shared Jaguar and Land Rover diagnostics guide for the tool history, coverage notes and sources.
Ford's contemporary WDS announcement named Jaguar in its planned 2000 dealer rollout; a later JLR IDS manual listed Jaguar from 1995 model year. These describe different periods and do not mean that all software versions are interchangeable. Ford WDS announcement; JLR IDS general information.
