Service bulletin SSM 51884

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 Mustang vehicles may set diagnostic trouble code (DTC) U211B:87 in the ABS module during a diagnostic self-test. This may be due to the modules DTC sensitivity during vehicle key-on/start-up. Replacement or reprogramming of the ABS module may not resolve this condition. U211B:87 should be ignored if: no other DTCs are present, no warning indicators are illuminated while the engine is running, and no noticeable symptoms are present. No further service action is required.
