SSM 52606

Some 2023-2024 F-Super Duty vehicles equipped with a keyed ignition may exhibit a "Vehicle May Not Start/Restart Service Now" message in the instrument panel cluster (IPC) with diagnostic trouble code (DTC) U300A:01 stored in the body control module (BCM). This may be due to an obstruction of the ignition key due to a mispositioned grommet around the ignition lock cylinder. To correct this condition, reseat the grommet. This may require full or partial removal of the center instrument panel trim which the grommet seats into. Refer to Workshop Manual (WSM), Section 501-12. Once complete, make sure there is no restriction to movement and retest. If the condition persists, refer to normal diagnostics in WSM, Section 211-05.
