SSM 53208 2022-2023 F-150 Lightning - Reduced Driving Range Projection And HV Battery Pack SOC - Unable To Reach Target Charge

[Mike G]

5 Dec 24 Posted in case these symptoms are what you're experiencing:
"Some 2022-2023 F-150 Lightning vehicles may exhibit a reduced distance to empty (DTE) projection, a high voltage (HV) battery pack state of charge (SOC) that drops from 100% to less than 90% within 60 seconds of being driven, and an inability to reach a target SOC using the scheduled charging feature without any diagnostic trouble codes (DTCs) in the battery energy control module (BECM). This may be due to an issue in one or more cells within the HV battery pack. To correct the condition, run the "BECM Battery Health" application using the latest software version of the Ford Diagnosis and Repair System (FDRS). If any cells are identified as exceeding state of charge and/or capacity thresholds, refer to the Workshop Manual (WSM), Section 414-03A High Voltage Battery, Mounting and Cables > Diagnosis and Testing > High Voltage Battery, Mounting and Cables - Electric > Pinpoint Test AP > Step AP4 and continue diagnosis. If all cells are within state of charge and capacity thresholds or DTCs are present in the BECM, refer to the WSM for normal diagnosis."

Mike:

Can that be run remotely or does the vehicle need to be connected to FDRS?

FDRS is where that Battery Health tool is. Must be directly connected.

Thanks.

This is helpful information for a few threads discussing sudden drops in SOC.

This is helpful information for a few threads discussing sudden drops in SOC.

Mine drops 3% after half a mile in the afternoon lately, I don't think that's related to this though. I've ignored it as my overall usage by the time I get home is about on par with what I expect.

My truck 22ER Lariat is doing exactly this. It'll say it's at 100% then immediately drops to 88% when put in drive. My charge logs also indicate it stopping at 88%. i checked on carscanner app and its getting to 81.4%actual and 100% displayed. Then drops to 88.5% displayed at the same actual soc. Pack voltage seems high for 81% showing 392v. Showing 99.5%SOH 0.08v module variation and 7.54% module soc variation. I'm at 65k miles. I've been hoping this would fix itself. Have not had any real issues until now but the truck still runs fine and does not have any warnings or dtc's
