Component Description: GFM

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The GFM is the controlling ECU for the trailer TPMS and contains a radio signal receiver which collects the tire pressure data from the trailer TPMS sensors. When a new GFM is installed, the number of wheels on the trailer and the upper pressure limit for the tires must be programmed into the GFM using the message center menu and the buttons on the steering wheel. For additional information on programming the GFM with the number of TPMS sensors and the tire pressure threshold, refer to the Owner's Literature.
