Ford DiagNow is a mobile application designed for convenient vehicle diagnostics, allowing users to quickly identify and address concerns without requiring a full diagnostic scan tool. This lightweight app is compatible with any 2010 or newer Ford, Lincoln, and Mercury vehicles, providing a range of essential diagnostic features.

Users can read and decode the Vehicle Identification Number, clear Diagnostic Trouble Codes, monitor live data parameters, and perform key programming. Additionally, the app allows users to view service bulletins related to Diagnostic Trouble Codes. To utilize the diagnostic functions, a valid Ford Dealer or Ford Motorcraft account with a subscription is necessary, along with the Ford VCM Lite interface.
