Certain Palisade (LX3) and Palisade Hybrid (LX3 HEV) vehicles may exhibit a “Check Active Air Flap System" warning message, Engine MIL ON, and/or “Low Engine Oil" warning message, due to improper operation of the Active Air Flap (AAF) system. DTCs include, but are not limited to: P05AE00, P05B100, P05B200, P05B400, P05FE00, P15A200, P15A500, P2C7400, U028500, U028B00, and/or U100800. This condition may be caused by water ingress and corrosion at the wiring connections for the lower AAF actuators and/or sensors.

Some 2022 Broncos equipped with a 2.3L engine and built on 01-Apr-2022 and through 08-Apr-2022 may exhibit a charging system fault message displayed in the IPC and diagnostic trouble codes (DTCs) U012D, U0284 and/or U0285 stored in the powertrain control module (PCM). This may be due to a poor electrical connection at connector C1104B, pin 1 (circuit VE181) located at the generator. To correct this condition, replace connector C1104B with a service pigtail replacement service part number: LU2Z-14S411-ACA.

Some 2021-2022 F-150 vehicles equipped with a 2.7L EcoBoost engine may experience a Check Charging System message displayed in the instrument panel cluster (IPC). The following diagnostic trouble codes (DTCs) may also be stored in the powertrain control module (PCM): U012D, U042E, U0284, U0285, and/or U0645. This may be due to local interconnect network (LIN) circuit VE181 (WH-GN), near connector C102A, being shorted to ground near the left engine mount bracket. If this wire is found to be shorted, repair as need per Wiring Diagram, Cell 005 and secure the harness assembly away from the engine mount bracket to prevent a recurrence.

FORD · 2021-10-14

Some 2021 Bronco vehicles built on or before 23-Aug-2021 may experience a charging system fault message displayed in the instrument panel cluster (IPC) and diagnostic trouble codes (DTC) U012D, U0284 and/or U0285 stored in the powertrain control module (PCM). This may be due to water intrusion in the active grille shutter connector. To correct this condition, follow the Service Procedure to inspect for water intrusion in the active grille shutter harness connector and repair as needed.
