Portable Diagnostic Software (PDS): PDS operates on approved Pocket-PC's, providing high end scan tool diagnostic software for use with a Vehicle Communication Module (VCM). PDS functionality is vehicle dependent and may include tools such as Self Test, Datalogger, Module Reprogramming, Power Balance, and many other Service Functions. As a portable scan tool, PDS can be used both in the service bay and for on-the-road testing. PDS is not intended to be used as the sole diagnostic tool. IDS provides 100% coverage. PDS File Manager (PFM): To support PDS, users will need access to a PC for software, database and module programming file updates. The PDS File Manager (PFM) application will run on your base PC and handle updating your PDS Pocket-PC with these software and file updates from the Web and/or DVD. PDS Vehicle coverage: PDS supports most Ford, Lincoln and Mercury vehicles from 1996 forward that have a 16-pin DLC (OBDII) connector under the dash. On vehicles with both a 16-pin connector and another connector, PDS supports only the modules on the 16-pin DLC (OBDII) link. Actual vehicle and software coverage may vary. IDS (Integrated Diagnostic System) may be required for full functionality. The chart below compares PDS and IDS functionality. PDS IDS Functionality Matrix
