SSM 51705

Some 2021-2023 Mustang Mach-E and 2022-2023 E-Transit vehicles may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTC) P0ADA, P0ADE, P0AA1, and/or P0AA4 stored in the battery energy control module (BECM) after high voltage battery junction box (HVBJB) replacement. Vehicle may also exhibit reduced powertrain performance and/or a Stop Safely Now message displayed in the instrument panel cluster (IPC) and/or High-Voltage Battery Warning message in the FordPass application. This may be due to the BECM software. To correct the condition, download and run the BECM - Reset Diagnostic Trouble Code (DTC) Occurrence Counter application in Ford Diagnosis and Repair System (FDRS). If the concern persists, refer to Workshop Manual (WSM), Section 414-03A for normal diagnostics.
