SSM 522442024-02-14. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2021-2023 F-150 vehicles equipped with a 3.5L PowerBoost hybrid engine, 2020-2023 Explorer vehicles equipped with a 3.3L hybrid engine and 2020-2023 Aviator vehicles equipped with a 3.0L hybrid engine may exhibit a malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0A1E stored in the powertrain control module (PCM) and auto start/stop disabled. This may be due to a loose wiring connection to the belt integrated starter generator (BISG). The Workshop Manual (WSM) has recently been updated to provide new direction for DTC P0A1E. Refer to the WSM, Section 303-06 Starting System, Diagnosis and Testing, Starting System for applicable diagnosis.
SSM 506222022-03-30. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some 2020 - 2022 Explorer/Aviator/Police Interceptor Utility vehicles may display a distance to empty value in the instrument panel cluster (IPC) that does not correctly represent the actual fuel level of the vehicle. This may be due to excessive idling and/or a learned value in the powertrain control module (PCM) that is incorrect. To correct the condition, perform the PCM - Reset the Keep Alive Memory (KAM) application in the appropriate Ford diagnostic scan tool. For claiming, use Causal Part 12A650 and applicable labor times from Section 10 in the Service Labor Time Standards (SLTS) Manual.
TSB 21-24522022-01-01. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). 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).
TSB 21-24342022-01-01. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM).

This may be due to sticking valves in the main control valve body. To correct the condition, follow the Service Procedure steps to perform the PCM - Transmission Accelerated Main Control Break In routine for the appropriate clutch(s) and/or overhaul the main control valve body.
