Official summary
Some 2023 F-Super Duty vehicles may set diagnostic trouble code (DTC) U0415 in the all-wheel drive (AWD) module during a diagnostic self-test. This DTC sets when the AWD module does not detect a valid signal from the anti-lock brake (ABS) module through the controller area network (CAN) within a specified time frame. U0415 should be ignored if: no other DTCs are present in the ABS module or AWD module, 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.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
