Service bulletin TSB 20-2354

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2020 Aviator vehicles built on or before 17-Sep-2020 equipped with a 3.0L hybrid engine may exhibit occasional harsh shifts and/or a buck/jerk/hesitation condition at low speeds with no diagnostic trouble codes (DTCs) stored in the powertrain control module (PCM). This may be due to the software in the PCM. To correct the condition, follow the Service Procedure to reprogram the PCM.

Other bulletins for the same vehicles and component
SSM 52244	2024-02-14. Service bulletin. 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 51032	2022-08-22. Service bulletin. Some 2020-2022 Explorer/Aviator vehicles may exhibit automatic transmission fluid (ATF) contamination in the engine cooling system due to the transmission cooler. If the cooling system becomes contaminated with ATF, the system must be flushed clear of the contamination after the source of the contamination has been repaired. It is generally not necessary to replace the following components due to ATF contamination in the cooling system: radiator, heater core, de-gas bottle, water pump, auxiliary water pump, coolant control valves, temperature sensors, thermostat, turbocharger, heat exchangers, tubes, gaskets/O-rings/seals (unless removed), or rubber coolant hoses (unless swollen).
SSM 50885	2022-06-30. Service bulletin. 2020-2022 Explorer/Aviator and 2021-2022 F-150 hybrid vehicles equipped with a 10R80 MHT require the Transmission Strategy Download application in the Ford Diagnosis and Repair System (FDRS) to be run after certain transmission or module repairs. The Transmission Strategy Download routine is failing in FDRS levels 32.5.3 and 32.5.4. The FDRS development team is working to resolve this in a future release of FDRS. In the meantime, uninstall FDRS from the computer using the select all function to remove all data and recordings. Reinstall the older FDRS version 31.6.5 using this url - http://www.fordservicecontent.com/Ford_Content/IDS/FDRS/FDRS_31.6.5.exe Once 31.6.5 is installed, download and run the Transmission Strategy Download application.
SSM 50622	2022-03-30. Service bulletin. 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 21-2452	2022-01-01. Service bulletin. 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 21-2434	2022-01-01. Service bulletin. Some 2020-2022 Explorer/Aviator/Police Interceptor Utility vehicles and 2021 F-150 vehicles equipped with a 10R80 MHT automatic transmission may exhibit a harsh/delayed engagement and/or a harsh/delayed shift with or without an illuminated malfunction indicator lamp (MIL) or diagnostic trouble codes (DTC) P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6, P07F7, P2700, P2701, P2702, P2703, P2704 and/or P2705 stored in the powertrain control module (PCM). 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.
SSM 49821	2021-06-01. Service bulletin. Some 2015-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes (DTC) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. This may be due to small debris causing the VCT solenoid to stick. Before attempting any component diagnosis or replacement of the VCT solenoid, refer to Powertrain Control and Emissions Diagnosis (PC/ED) pinpoint test HK11 to cycle the affected VCT solenoid 10 times to attempt to clear the debris. For claiming, use causal part 6M280 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
TSB 20-2405	2020-12-05. Service bulletin. Some 2020 Explorer/Aviator/Police Interceptor Utility vehicles equipped with a 3.0L EcoBoost engine may exhibit a rough idle with the air conditioning (A/C) on. 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.
SSM 49292	2020-11-04. Service bulletin. Some 2018-2020 Ford and Lincoln vehicles may exhibit inoperative remote features via the Ford Pass/Lincoln Way mobile app, incomplete user authorization, no modem electronic serial number (ESN) displayed or DTCs U2100 and/or B156D in the telematics control unit (TCU). These symptoms may persist even after performing a TCU software update and/or replacement. To correct this condition, start a new session with the latest version of the appropriate diagnostic scan tool and perform a PMI on the TCU. If issues persist, open a hotline assistance request and include the IDS version (if applicable) used to perform the PMI and the Authorization Status PID value in the TCU datalogger. For claiming use causal part 14H092 and applicable labor times in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 49162	2020-10-06. Service bulletin. Some 2020 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.
