Ford DiagNow is a handy diagnostic tool for owners of 2010 or newer Ford, Lincoln, and Mercury vehicles. Developed by Ford Motor Company, this free app provides users with the ability to address vehicle concerns without the need for a full diagnostic scan tool and laptop.

With Ford DiagNow, users can access a range of diagnostic functionalities. They can read and decode the Vehicle Identification Number (VIN) to obtain specific model information. The app also allows users to read and clear Diagnostic Trouble Codes (DTCs) for all equipped vehicle electronic control modules. Additionally, users can read live data parameters from the vehicle and perform live vehicle network monitoring.

Ford DiagNow also offers key programming functionality, allowing users to program new keys for their vehicles. Users can also read their factory keyless entry code through the app. The app also provides access to service bulletins and messages related to the DTCs read from the vehicle.

To use Ford DiagNow, users must have a valid Ford Dealer account or Ford Motorcraft account with a Ford DiagNow subscription. The app requires the Ford VCM Lite interface to perform diagnostic functions with the vehicle.

Please note that key programming and factory keyless entry code features currently function on most 2010 Ford, Lincoln, and Mercury vehicles, with additional vehicle support coming soon.
