Official summary
This article supersedes TSB 21-2295 to update the Parts List. Some 2021 F-150 vehicles built on or before 14-June-2021 may exhibit a rubbing noise at the front of the vehicle while driving and/or diagnostic trouble codes (DTC) C0031 and/or C0034 in the anti-lock brake system (ABS) module. This may be caused by an incorrectly routed front brake flexible hose. To correct the condition, follow the Service Procedure to inspect the front brake flexible hose routing.
Vehicles covered
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.
