Service bulletin SSM 53979

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2024-2025 Ranger vehicles may exhibit a "Check Charging System" message displayed in the instrument panel cluster (IPC) with diagnostic trouble codes (DTC) U012D, U0284, and/or U042E stored in the powertrain control module (PCM). This may be due to corrosion found in the active grille shutter lower connector (C1767). If no corrosion is found in this connector, refer to the Workshop Manual (WSM), Section 414-00 for normal diagnostics. If corrosion is found, replace the connector and active grille shutter (AGS) actuator (base part number: 10884). To aid in engineering investigation, when removing the corroded connector cut the wires about 3 inches (76 mm) from the connector to ensure adequate wire is left for analysis. If the corrosion condition is encountered, use the "Submit Global Concern Report (GCR)" link at the upper right of the Vehicle ID tab to submit a report and reference this article number in the report. For claiming, use causal part 14290 and labor operations 12650D, 12650D45, 12650D45WR, 12650D78LW, 12650D78BU, 12650D78CM, and/or 12650D78TD in Section 10 of the Service Labor Time Stand

SSM 551182026-09-01. Service bulletin. Some of the following vehicles: * 2023-2025 F-Super Duty built on or before 02-Feb-2025 * 2024-2026 Ranger/Bronco/Mustang * 2024-2025 F-150 built on or before 15-Jul-2025 * 2024-2025 Nautilus built on or before 16-Feb-2025 * 2025 Explorer/Aviator built on or before 01-Feb-2025 may exhibit all of the following symptoms: - "No Key Detected" message displayed on the instrument panel cluster (IPC). - Key fob does not work in the backup slot. - Remote keyless entry (RKE) (lock and unlock from the key fob) functionality will work to lock/unlock the vehicle. If the vehicle exhibits these symptoms, start the vehicle using both key fobs. If the no crank/no start condition with "No Key Detected" concern is present, reprogram both key fobs and retest. If the no crank/no start condition with "No Key Detected" is still present, replace the body control module (BCM). Refer to Workshop Manual (WSM), Section 419-10. For claiming, use causal part 15604 and labor operation MT55118SSM up to 1.8 hours.
SSM 551132026-09-01. Service bulletin. Some 2024-2025 Ranger vehicles equipped with a cargo box power point plug may exhibit a condition where all interior/exterior power outlets/plugs are inoperative with diagnostic trouble code (DTC) B1330:9A stored in the body control module (BCM). This may be due to an inoperative light emitting diode (LED) in the cargo box power point plug. To correct the condition, replace the cargo box power point plug (service base part number 19A464). Refer to Workshop Manual (WSM), Section 414-05 > Removal and Installation > Alternating Current (AC) Power Outlet Socket > Cargo Box Power Point Plug. For claiming, use causal part 19A464 and labor operation MT19A464SSM up to 0.6 hours.

Some 2024-2025 Ranger vehicles equipped with a cargo box power point plug may exhibit a condition where all interior/exterior power outlets/plugs are inoperative with diagnostic trouble code (DTC) B1330:9A stored in the body control module (BCM). This may be due to an inoperative light emitting diode (LED) in the cargo box power point plug. To correct the condition, replace the cargo box power point plug (service base part number 19A464). Refer to Workshop Manual (WSM), Section 414-05 > Removal and Installation > Alternating Current (AC) Power Outlet Socket > Cargo Box Power Point Plug. For claiming, use causal part 19A464 and claim M-time up to 0.6 hours.
SSM 550442026-07-27. Service bulletin. Some 2025-2026 Bronco/Ranger vehicles may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) P2122, P2123, P2127, P2128, and/or P2138 stored in the powertrain control module (PCM). The vehicle may or may not exhibit a perceived lack of power intermittently. This may be due to an issue with the following connectors associated with the accelerator pedal position (APP) sensor circuits: -C115B -C175B -C2040 Replacement of the accelerator pedal may not resolve this concern. Perform a wiggle test of the connectors while the engine is at normal operating temperature. Perform a visual inspection of the connectors as well as a terminal fit test using the appropriately sized flex probe. Repair as necessary. Refer to Wiring Diagram Cell 005. If no concerns are found, refer to Workshop Manual (WSM), Section 310-02 for normal diagnostics.
TSB 26-23012026-07-01. Service bulletin. Some of the vehicles listed in the Model statement above may require the replacement of the ambient air temperature sensor for various concerns. DTCs P0071, P0072, and/or P0073 may be present in the powertrain control module (PCM).
SSM 549022026-06-09. Service bulletin. For 20202026 vehicles equipped with the 10R60 transmission, a new Transmission Clutch Circuit Leak Test has been introduced in the Ford Diagnosis and Repair System (FDRS). This test utilizes the pressure and vacuum transducer (PVT) when available. Workshop Manual (WSM) updates related to this diagnostic procedure are planned for release in Q4 2026. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method. The previous air check procedure has been shown to produce a high rate of false positives, which may lead to unnecessary repairs when no actual leak is present. Accordingly, the air check procedure is not to be used for diagnosing internal transmission hydraulic leaks or as justification for transmission replacement.
