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.
