2023 F-Super Duty - DTC U211B:87 Setting In Various Modules When A
Diagnostic Self Test Is Performed
Some 2023 F-Super Duty vehicles may set diagnostic trouble code (DTC) U211B:87 in various modules when
a diagnostic self-test is performed, which includes: powertrain control module (PCM), advanced driver
assistance system (ADAS), anti-lock brake system (ABS), power steering control module (PSCM), body
control module (BCM), telematics control unit (TCU), driver door module (DDM), and/or passengers door
module (PDM). This may be due to the modules DTC sensitivity during vehicle key-on/start-up. Replacement
or reprogramming of these module(s) 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.
