Why is the 2016 ford f150 usb port not working?

The 2016 Ford F-150's USB port can stop working if the battery has recently been disconnected and reconnected. However, if Apple CarPlay is not functional as well, the port may have been shorted by a faulty cable connection. Under these conditions, Ford SYNC will shut down power to the USB port. To restore function, perform a master reset of Ford's SYNC by navigating through the central display's main menu. After a factory reset is initiated, turn the truck on and off to finish calibration. The SYNC fuse is located on the right hand side of the instrument panel and is a 15 amp plug numbered #2. Occasionally, ports need to be replaced and installing a new USB outlet might be necessary. The most probable cause is disconnected or shorted electrical connections behind the radio head unit itself. Have a professional examine the radio's wiring harnesses and connections for failure.
