WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The GFM2, or UIM (upfitter interface module), is located behind the glove box. If it is necessary to replace the GFM2 the program (source file) needs to be obtained from the upfitter and uploaded to the new module via the upfitter GUI (graphical user interface). The program cannot be copied from the original GFM2, and is not stored in any other module or on PTS: There is no backup file. Contact the upfitter to obtain a copy of the GFM2 source file. Refer to: Body Control Module (BCM) - Component Location .
