Manufacturer summary

Original wording in English

Some 2020-2021 F-Super Duty vehicles may exhibit an inoperative radio, no communication with the audio front control module (ACM), and/or diagnostic code (DTC) U0184 stored in the SYNC module (APIM) or instrument panel cluster (IPC). If the vehicle is in transport mode, disable transport mode and retest. Refer to Workshop Manual (WSM), Section 419-10. If the concern is still present, perform a radio power reset by removing fuse F32 in the body control module (BCM) for 5 minutes. Reinstall the fuse and retest. If the concern is present, disconnect connector C240A from the ACM, reconnect, and retest. If the vehicle still exhibits the concern, refer to WSM, Section 415-00 and proceed with normal diagnostics.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
