Ford IDS/VCM 87 description of the catalogue:

Ford Integrated Diagnostic System (IDS):
The Ford Integrated Diagnostic System (IDS) will be the only equipment that provides complete diagnostic coverage of current and future Ford, Lincoln and Mercury vehicles in North America. 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 service Ford, Lincoln, Mercury 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.
