Some 2024 Nautilus vehicles may set diagnostic trouble code (DTC) U3001:68 in the power steering control module (PSCM) when a diagnostic self-test is performed. This may be due to an internal counter reaching a specified limit. U3001:68 has no effect on functionality and will automatically become a historical DTC which can be cleared. Replacement or reprogramming of the PSCM module will not resolve this condition. Engineering is currently working on a software update which is expected in Q1 2024. Continue to monitor OASIS for additional information.

Some 2021 F-150 vehicles may exhibit a lack of steering assist upon start-up along with a Steering Assist Fault message in the instrument panel cluster (IPC) with DTC U3001:68 and/or U3001:89 along with U3000:96 in the power steering control module (PSCM). This may be due to low battery voltage when attempting to start the vehicle. Power steering assist will be restored when battery voltage is at or above 12 volts and the DTCs are cleared. Replacement of the PSCM is not necessary. Flash the PSCM to the latest software level and clear the DTCs afterwards. Once cleared, cycle the ignition to verify normal system operation. If the DTCs return, refer to Workshop Manual Section 211-02 for normal diagnostics. For claiming, use causal part 3504 and applicable labor operations in Section 10 of…

Some 2021-2023 F-150 vehicles may experience a lack of steering assist upon start-up along with a Steering Assist Fault message in the instrument panel cluster (IPC) with diagnostic trouble codes (DTC) U3001:89 and U3000:96 in the power steering control module (PSCM). This may be due to low voltage at the PSCM. Power steering assist will be restored when sufficient voltage is supplied. To clear the DTCs using the Ford Diagnosis and Repair System (FDRS), select and run the PSCM - Reset the Power Steering Control Module (PSCM) application. Once cleared, cycle the ignition to verify normal system operation. If the DTCs return, refer to Workshop Manual Section 211-02 for normal diagnostics. For claiming, use causal part 3504.

Some 2021 F-150 vehicles built on or before 17-Mar-2021 may experience a lack of steering assist upon start-up along with a Steering Assist Fault message in the instrument panel cluster (IPC) with diagnostic trouble codes (DTC) U3000:96 and U3001:68 in the power steering control module (PSCM). This may be due to battery voltage below 8 volts when attempting to start the vehicle. Power steering assist will be restored when battery voltage is at or above 12 volts and the DTCs are cleared. Replacement of the PSCM is not necessary. To clear the DTCs using the FDRS, select and run the PSCM - Reset the Power Steering Control Module (PSCM) application.
