SSM 52589

Some 2024 Mustang vehicles built on or before 10-Feb-2024 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.
