| SSM 55172 | 2026-09-21. Service bulletin. Some 2025 Aviator/Explorer/Police Interceptor Utility vehicles may exhibit a "Steering Assist Fault Service Required" message and diagnostic trouble codes (DTC) C1110:56 and/or U3000:96 stored in the power steering control module (PSCM) after programming. This may be due to a calibration mismatch in the PSCM which has been resolved in the Ford database. If DTC C1110:56 is stored in a replacement PSCM after completing programmable module installation (PMI), start a new session using the latest software version of the Ford Diagnosis and Repair System (FDRS) scan tool then run the "PSCM - Programmable Module Installation (PMI)" application again. When FDRS asks if the original module is installed, select "No". If DTC C1110:56 is stored in the original PSCM after performing the PSCM configuration, start a new session using the latest software version of the FDRS scan tool, then download and run the "PSCM - Power Steering Control Module (PSCM) Software Update" application. To clear DTC U3000:96 from the PSCM, download and run the "PSCM - Reset the Power Steering Control |

| SSM 54399 | 2025-12-01. Service bulletin. Some 2025 Aviator/Explorer/Police Interceptor Utility vehicles may exhibit diagnostic trouble code (DTC) C1110:56 and/or U3000:96 stored in the power steering control module (PSCM) after programming the PSCM, or may display the following message in Ford Diagnosis and Repair System (FDRS) when performing PSCM programmable module installation (PMI): <br /><br /> "It has been detected that a Model Year 2025 Steering Gear (R1MC - level) is fitted to this vehicle. It is not possible to run the Power Steering Control Module (PSCM) Programmable Module Installation (PMI) application on this Steering Gear. If later software is available, this PSCM can be updated by running the PSCM Software Update application."<br /><br /> This may be due to the calibration in the PSCM. When installing a replacement steering gear, make sure the part number begins with prefix "S1MZ". If DTC U3000:96 previously set after programming the PSCM, continue with normal diagnostics outside this article. Refer to Workshop Manual (WSM), Section 211-02 > Diagnosis and Testing.
