Jaguar & Land Rover IDS 135 description of the catalogue:

Jaguar, Land Rover Integrated Diagnostic System (IDS):
The Jaguar, Land Rover Integrated Diagnostic System (IDS) will be the only equipment that provides complete diagnostic coverage of current and future Jaguar, Land Rover vehicles. The IDS package replaces the Worldwide Diagnostic System (WDS). The IDS application will perform the identical functions of the WDS and allows dealership technicians to diagnose and serviceJaguar, Land Rover vehicles. As the new diagnostic tool, IDS will be required to perform diagnostics on future model year vehicles. One IDS Package is recommended for each WDS in the dealership.

IDS is enhanced WDS software that was modified to run on a standard laptop platform, and utilizes the VCM and VMM. Moving IDS to a laptop helps technicians by integrating access to both diagnostics and service information on a single, powerful machine.
