TSB 23-2348

This article supersedes TSB 23-2257 to update the Parts List. Some 2021-2023 Mustang Mach-E vehicles built on or before 17-Mar-2023 may exhibit an illuminated malfunction indicator lamp (MIL) and/or powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTCs) P0563, P0ADA, P0ADE, P0AA1, P0AA4, P0AA5, P0AA2, P0D10, P0D0F, and/or P0C78 stored in battery energy control module (BECM). It may also have a low/discharged 12V battery and/or display a Stop Safely Now message in the instrument panel cluster (IPC). This may be due to the high voltage battery junction box (HVBJB). To correct the condition, follow the Service Procedure to replace the HVBJB and reprogram the BECM.
