# Other 26E03

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.

## Other bulletins for the same vehicles and component

- [SSM 55208](/bulletins/11037569.md), 2026-09-30, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM. Some 2024\-2026 F\-150, 2025 Explorer/Aviator, 2025\-2026 Expedition/Navigator, or 2026 F\-Super Duty vehicles may exhibit diagnostic trouble code \(DTC\) U211B:43:48 stored in the body control module \(BCM\) when performing a Self\-Test. This DTC sets due to an internal BCM timing issue during the self\-test process. This specific code has no customer impact and does not cause any drivability concerns or warning messages. Clearing DTC U211B:43:48, reprogramming the BCM, or replacing the BCM is unlikely to prevent this DTC from setting. This DTC does not trigger a condition covered under warranty. Note: This guidance only applies to U211B with the specific failure byte 43 in status 48. Any other trusted real\-time operation network \(TRON\) DTCs or different failure bytes associated with U211B are still applicable and technicians must follow Workshop Manual \(WSM\) normal diagnostics for those DTCs.

- [SSM 55131](/bulletins/11036601.md), 2026-09-02, Service bulletin: ELECTRICAL SYSTEM; VEHICLE SPEED CONTROL; UNKNOWN OR OTHER. Some 2025\-2026 Aviator/Explorer/Expedition/F\-150/Mustang Mach\-E/Nautilus/Navigator vehicles may exhibit the hands\-free BlueCruise feature intermittently/consistently unavailable when BlueCruise is active and when traveling in a "Blue Zone". Speed sign recognition may also be inaccurate. If there are no active relevant diagnostic trouble codes \(DTC\) present and the issue persists after multiple key cycles and if the BlueCruise System Health Check passes, download and run the "TCU \- Reset Telematics Control Unit \(TCU\) Module" application using the latest software level of the Ford Diagnosis and Repair System \(FDRS\). If the condition is resolved, inform customers that this may be a temporary fix and engineering is currently working on a solution expected in Q4 2026. Monitor Professional Technician System \(PTS\) for additional information and schedule service appointments for customers once the repair becomes available. For claiming, use causal 14G229 and labor operations 12651D and 12651D4. If the condition persists after a test drive, refer to Workshop Manual \(WSM\), Section 419\-03B for normal
- [SSM 55116](/bulletins/11036525.md), 2026-09-01, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM. Some of the following vehicles: \* 2025\-2026 Expedition/Navigator built on or after 02\-Feb\-2025 \* 2025\-2026 F\-Super Duty built on or after 02\-Feb\-2025 \* 2025\-2026 Explorer/Aviator built on or after 02\-Feb\-2025 \* 2025\-2026 Nautilus built on or after 17\-Feb\-2025 \* 2025\-2026 F\-150 built on or after 16\-Jul\-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, manually enter the vehicle identification number \(VIN\) into the VIN entry dialog in the Ford Diagnosis and Repair System \(FDRS\) and then start a session using the Vehicle Communication Module \(VCM\) II, VCM 3, Vehicle Communication and Measurement Module \(VCMM\) or later level device with a universal serial bus \(USB\) cable disconnected from the laptop.

- [SSM 55111](/bulletins/11036522.md), 2026-09-01, Service bulletin: ELECTRICAL SYSTEM; FUEL/PROPULSION SYSTEM. Some 2022\-2026 F\-150 Lightning vehicles may exhibit a reduced distance to empty \(DTE\) projection, a high voltage battery pack state of charge \(SOC\) that drops from 100% to less than 90% within 60 seconds of being driven, and an inability to reach a target SOC using the scheduled charging feature without any diagnostic trouble codes \(DTCs\) in the battery energy control module \(BECM\). This may be due to an issue in one or more cells within the high voltage battery pack. To correct the condition, run the "BECM Battery Health" application using the latest software version of the Ford Diagnosis and Repair System \(FDRS\). If any cells are identified as exceeding state of charge and/or capacity thresholds, refer to the Workshop Manual \(WSM\), Section 414\-03A High Voltage Battery, Mounting and Cables \> Diagnosis and Testing \> High Voltage Battery, Mounting and Cables Electric. Perform Pinpoint Test High Voltage Battery Pack Cell Balancing Faults, Step 4 \(PPT Step AO4 for 2022\-2024 vehicles/PPT Step AQ4 for 2024\-2026 vehicles\) and proceed with Pinpoint Test directions following the results of Step 4.

Some of the vehicles listed in the Model Statement above may exhibit an intermittent extended crank with no relevant diagnostic trouble codes \(DTCs\) present. This may be due to various software parameters in the powertrain control module \(PCM\).
