Some 2020 Aviator vehicles equipped with a 3.0L hybrid engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0C48, P0C49, P2B29, P0CFF, P0E1F, P0C4B, P0C4A, P2CF3, P0A06, P0A07, P2D01, P2D00, P2D03, P2D04, P0C73, and/or P2D02 stored in the powertrain control module (PCM). This may be due to the software in the battery energy control module (BECM). To correct the condition, follow the Service Procedure to reprogram the BECM.
