Bulletin Summary
Some 2020-2021 Aviator vehicles equipped with a 3.0L PHEV powertrain may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) U0100, P1A42 and/or P1A43 stored in battery energy control module (BECM). This may be due to software in the PCM. To correct the condition, follow the service procedure to perform a coordinated flash on the powertrain control module (PCM), secondary on-board diagnostic module c (SOBDMC), anti-lock braking system (ABS) module, BECM, and battery charger control module (BCCM).
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
