Some 2021-2024 F-150 vehicles may exhibit a side door ajar and/or a hood ajar warning message displayed in the instrument panel cluster (IPC) with or without diagnostic trouble codes (DTC) P166B, B1175, B1176, B11C1 and/or B11C0. This may be due to a misalignment of the the door or hood and/or their strikers. Before attempting any component diagnosis or replacement, check the door and/or hood and their strikers for proper alignment. Refer to Workshop Manual (WSM), Section 501-03 alignment procedures. If the doors and hood are properly aligned, continue with normal diagnostics.

Some 2020-2023 Aviator vehicles built on or before 12-Oct-2022 may exhibit a door ajar or door fault warning message present in the message center with diagnostic trouble codes (DTCs) B1175:19, B1176:19, B11C0:19 and/or B11C1:19 present in door latch control module E (DCME), door latch control module F (DCMF), door latch control module G (DCMG) and/or door latch control module H (DCMH). This may be due to low battery voltage and DTC thresholds being too low and not a fault in the door latch assembly. To correct the condition, reprogram and re-configure the the affected module using the latest level of the Ford Diagnosis and Repair System (FDRS). For claiming use causal part 54264A27 and applicable labor times found in Section 10 of the Service Labor Time Standards (SLTS) Manual.

Some 2020-2022 Aviator vehicles may exhibit a door ajar or door fault warning message present in the message center with diagnostic trouble codes (DTCs) B1175:19, B1176:19, B11C0:19 and/or B11C1:19 present in door latch control module E (DCME), door latch control module F (DCMF), door latch control module G (DCMG) and/or door latch control module H (DCMH). This may be due to low battery voltage and DTC thresholds being too low and not a fault in the door latch assembly. Engineering is releasing updated software to resolve this concern, which is expected to be available by the end of June-2022. In the meantime, clear these DTC's and if any reset with normal battery voltage follow normal Workshop Manual diagnostics and repair. Monitor OASIS for updates.
