SSM 545842026-02-17. Service bulletin. ENGINE; UNKNOWN OR OTHER; ELECTRICAL SYSTEM. Some 2023-2026 F-Super Duty vehicles that require replacement of the heating ventilation and air conditioning (HVAC) module may have previously experienced a PMI that will not complete during installation. This may be due to a concern with the PMI application within the Ford Diagnosis and Repair System (FDRS) scan tool. To correct this condition, navigate to the FDRS application HVAC Programmable Module Installation (PMI). Click on the download button (if not already downloaded) or the refresh button on the right side of the application (if the application is already downloaded). Hover your mouse over the application name and verify the application version reads G2327867-5.0 or higher. Once the application is confirmed to be updated, run the HVAC PMI application.
SSM 542182025-09-18. Service bulletin. ENGINE. Some 2025-2026 F-Super Duty vehicles built on 10-Jun-2025 and through 11-Aug-2025 may exhibit the passenger side register not blowing cold air when commanded. This may be due to the heating, ventilation and air conditioning (HVAC) module calibration of the actuator. Download and run the "HVAC - Climate Control System Actuators Calibration" application with the Ford Diagnosis and Repair System (FDRS) and retest. If the concern remains, refer to the Workshop Manual (WSM), Section 412-00 for normal diagnostics. For claiming use causal part 19980 and labor operations 12651D and 12651D4. If this condition is encountered, enter a vehicle identification number (VIN) and click the "Submit Global Concern Report (GCR)" link at the upper right of the Professional Technician System (PTS) "Vehicle ID" screen. Fill out the GCR form, referencing this article number in the report.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
