Official summary
Some 2023 F-Super Duty vehicles may set diagnostic trouble code (DTC) U211B:08 in the ABS module during a diagnostic self-test. This may be due to the ABS modules DTC sensitivity during vehicle key-on/start-up. U211B:08 should be ignored if: no other DTCs are present in the ABS 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.
