Some 2020-2021 Explorer/Police Interceptor Utility vehicles equipped with a 3.3L hybrid engine and built on or before 21-Oct-2020 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) U0100 stored in the battery energy control module (BECM). This may be due to the software in the powertrain control module (PCM). To correct the condition, follow the Service Procedure to reprogram the PCM.
