TSB 23-2326

This article supersedes TSB 22-2496 to update the Title and production clean date. Some 2021-2023 Mustang Mach-E built on or before 15-Sep-2023 and 2022-2023 E-Transit vehicles may experience an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) P1A3C, U3000:16, U3000:64, U3000:04 and/or U3000:45 in the off-board charging controller (OBCC) module and the high voltage (HV) battery will not charge using a level 3 direct current (DC) fast charging station/electrical vehicle supply equipment (EVSE). This may be due to OBCC software. To correct the condition, follow the Service Procedure to reprogram the OBCC.
