Service bulletin SSM 55044

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 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 26-23802026-09-29. Service bulletin. This article supersedes TSB 25-2575 to update the Parts list to add the applicable body wiring harnesses and underbody shield bolts. Some vehicles listed in the Model statement above may exhibit a "Sta-bar Disconnect Service Required" message in the instrument panel cluster (IPC) with any of the following diagnostic trouble codes (DTCs) stored in the chassis control module (CHCM): C103A, C1A99, C1B03, C1B07, C1B14 and/or B1A67. This may be due to water intrusion in the stabilizer bar wiring harness connector.

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.
TSB 26-23722026-08-21. Service bulletin. This bulletin supersedes 26-2301. Reason for update: to update the Pinpoint Tests referenced in Step 1. 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 550792026-08-20. Service bulletin. Some 2025-2026 Bronco vehicles equipped with a 7 speaker audio system (minor feature code IDBAL) may exhibit diagnostic trouble codes (DTC) B128A:01, B128A:11, B128A:12, B128A:13, B1288:11, B1288:12 and/or B1238:17 stored in the audio front control module (ACM) with no customer facing symptoms related to those DTCs. Clear the DTCs and if the DTCs return with no customer facing symptoms, this condition may be due to the ACM software. Replacement of the ACM and/or speakers will not resolve this condition. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q4 2026. Continue to monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. If a vehicle exhibits this condition, enter the vehicle identification number (VIN) and click the "Submit Global Concern Report (GCR)" link at the upper right of the PTS "Vehicle ID" screen. Fill out the GCR form, referencing this article number in the report.
SSM 550732026-08-11. Service bulletin. Some 2021-2026 Bronco vehicles may require the removal and installation of the transfer case for various reasons. Installation requires Loctite® 243 adhesive applied to the mounting bolt threads in the transmission. Make sure that the mating faces are clean and dry. Tightening the mounting bolts also requires an updated two-stage tightening sequence. Workshop Manual (WSM), Sections 307-07C/D and 308-07C/D Installation > Transfer Case have been updated to reflect this change.
SSM 550702026-08-11. Service bulletin.
