Manufacturer summary

Original wording in English

Some 2020 F-Super Duty vehicles built on or before 10-Jul-2020 and equipped with an electronic steering actuator may exhibit increased steering effort at initial engine start-up, a Steering Assist Fault message present, and/or an illuminated steering warning indicator with diagnostic trouble code (DTC) U0131 stored in the instrument panel cluster (IPC). This may be due to the software in the power steering control module (PSCM). To correct the condition, follow the Service Procedure to update the software in the PSCM.

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.
