Some 2021-2023 F-150 vehicles may exhibit diagnostic trouble code (DTC) U023A:08 in the steering column control module (SCCM) after reprogramming the SCCM with no customer symptoms present. If the vehicles automatic high beam operation is fully functional, this DTC does not affect vehicle operation, and no additional diagnosis or service is required for this condition. Replacement or reprogramming of the SCCM or image processing module A (IPMA) will not resolve this condition. To validate that the automatic high beam system is fully operational, cover the light sensor located in the middle of the dashboard to activate the automatic low beam headlamps. Push the steering wheel multifunction switch forward to cycle through both high beam settings which will be represented in the instrument…

Some 2023-2026 F-Super Duty vehicles built on or before 01-Oct-2025 may exhibit a "Hill Start Assist Unavailable" and/or "Parking Brake Limited Function" message at vehicle start-up with diagnostic trouble codes (DTCs) U0151, U023A, U0159 and/or U0146 stored in the anti-lock brake system (ABS) module. These DTCs and/or U0415 may also be present in various other modules related to "invalid data received from the ABS control module". This may be due to the software in the ABS module. To correct the condition, reprogram the ABS module using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 2C219 and labor operations 2219D and 2219D44.

Some 2024 Mustang vehicles may exhibit a Pre-Collision Assist Not Available message and a Pre-Collision Assist Not Available indicator displayed in the IPC with DTC U023A stored in the steering column control module (SCCM) after the vehicle is remote started. The message and indicator should go away and normal operation of the pre-collision system should resume once the vehicle is shut down and then restarted using the push button start. This may be due to a low power mode issue with image processing module A (IPMA). To confirm the pre-collision system is operating properly, turn on the vehicle using the push button start (do not use remote start), the Pre-Collision Assist Not Available pop-up message and indicator should no longer be present. If the error message and indicator are not…

Some 2023 F-Super Duty vehicles may set diagnostic trouble codes (DTCS) U023A:00, U0159:00, and/or U0146:00 in the anti-lock brake system (ABS) module after the vehicle is remote started. This may be due to the image processing module A (IPMA) not communicating on the controller area network (CAN) during the remote starting event. Replacement or reprogramming of the ABS module or IPMA will not resolve this condition. U023A:00, U0159:00, and/or U0146:00 should be ignored if: no other DTCs are present in the ABS module, the malfunction indicator lamp (MIL) is not illuminated while the engine is running, and no drivability concerns are present. No further service action is required.

TechTip: In some cases, combination meters may automatically initialize for options detected on a specific vehicle. If a meter is exchanged between vehicles for diagnostic purposes, it may become unusable in the original vehicle. For example, if a combination meter is removed from a vehicle not equipped with LDA (Lane Departure Alert) and temporarily installed in a vehicle equipped with LDA, it may display ?CHECK LDA SYSTEM? on the multi-information display and set DTC U023A when reinstalled in the original vehicle. This condition cannot be reset, and the combination meter must be replaced.
