Special Service Message · SSM 55208

This is a Special Service Message, not a recall. SSMs are informational notes Ford sends dealers about a known condition or a change in procedure. They are not repair orders, and they don't by themselves change what is covered.

Applies to: F-250, F-350 (2026 model year)

Also listed in the source (outside this forum's coverage): Expedition 2025–2026, Explorer 2025, F-150 2024–2026, F-450 SD 2026, F-550 SD 2026

Summary (official text)​

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.
