| SSM 51675 | 2023-06-08. Service bulletin. Some 2023 F-Super Duty vehicles equipped with SYNC 4 may experience programming errors after a replacement of the body control module (BCM) for various concerns. After programmable module installation (PMI) of the new BCM, diagnostic trouble codes (DTC) U2100:00, U2101:00 and/or U211B:87 may be present. Download and run the Ford Diagnosis and Repair System (FDRS) application titled Trusted Real-Time Operation Network (TRON) Module Authentication, and perform the TRON Diagnosis and Repair and Reset ECU on CAN BUS routines. Once both TRON routines have been completed, re-run the BCM PMI application. Verify that all BCM DTCs have cleared. Service procedures are being updated to improve this process.
