Some 2023 F-Super Duty vehicles may set DTCs B109F:55, B1330:9A, U0252:87, U0198:87, U0184:87, U0155:87, U0256:87, and/or U0100:87 in the BCM when a diagnostic self-test is performed. This may be due to an incorrect sequence of an internal measurement unit during self-test causing a false history status DTC (0x48 or 0x08 status). The DTC matures to history status because the BCM detects nothing is wrong. Replacement or reprogramming of the BCM will not resolve this condition. B109F:55, B1330:9A, U0252:87, U0198:87, U0184:87, U0155:87, U0256:87, and/or U0100:87 should be ignored if: no other DTCs are present in the BCM, the malfunction indicator lamp (MIL) is not illuminated while the engine is running, and no drivability concerns are present. No further service action is required.

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.
