Bulletins for this model year that name B1C09
SSM 527342024-08-06. Service bulletin. Some 2024 F-150 vehicles may exhibit inoperative power exterior mirror glass adjustment with diagnostic trouble codes (DTCs) B1C09:11 and B1C10:11 in the driver's door module (DDM) or B1C11:11 and B1C12:11 in the passenger's door module (PDM). This may be due to module software logic responding to repetitive mirror switch input toggled up/down or left/right too quickly.
SSM 523842024-04-04. Service bulletin. Some 2024 F-150 vehicles may exhibit inoperative exterior mirror glass adjustment with diagnostic trouble codes (DTCs) B1C09:11 and B1C10:11 in the driver's door module (DDM) or B1C11:11 and B1C12:11 in the passenger's door module (PDM). This may be due to module software logic responding to repetitive mirror switch input toggled up/down or left/right too quickly. As an interim action, DDM/PDM functionality will resume after a sleep/wake cycle of approximately 15 minutes with the doors locked and the key in the OFF position. Inoperative outside mirror glass adjustment with DTCs B1C09:11 and B1C10:11 in the DDM or B1C11:11 and B1C12:11 in the PDM does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and a solution for this condition is expected in Q3 2024. Replacement or reprogramming of the DDM/PDM will not resolve this condition. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.
