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 519842023-11-03. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ENGINE AND ENGINE COOLING. Some 2022-2023 Explorer vehicles with 2.3L engine built on or before 20-Jul-2023 may exhibit an intermittent malfunction indicator light (MIL) with diagnostic trouble code (DTC) P1026 and/or P1299 present in the powertrain control module (PCM) and an engine over-temperature message displayed on the instrument panel cluster (IPC) after a cold engine start. The vehicle will also exhibit reduced performance when it enters fail safe cooling open loop mode. If the engine is not overheating, clear the DTCs to reset the fail safe cooling open loop mode. Start and idle the engine while viewing coolant flow at the top inner (engine side) degas bottle hose port through the semitransparent top. If there is no coolant flow, replace the L1MZ-8A365-AAD engine-to-degas bottle hose. If if there is any coolant flow, return to Workshop Manual (WSM), Section 303-03A diagnostics.
SSM 517642023-07-03. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ENGINE AND ENGINE COOLING. Some 2020-2023 Explorer/Aviator vehicles equipped with a 3.0L EcoBoost may exhibit an illuminated malfunction indicator lamp (MIL) and low oil pressure warning in the instrument panel cluster (IPC), with diagnostic trouble codes (DTC) P0521 and/or P0524 in the powertrain control module (PCM). This condition may be caused by an internal oil pressure leak. If pinpoint test E in the Workshop Manual (WSM) Section 303-01B directs you to the replacement of the oil pump, upon reassembly inspect that the main oil gallery tube (6718) is assembled and aligned properly on the back of the engine front cover. The engine oil gallery seal (00815) must be replaced any time the front cover is removed (per WSM Section 303-01B). The WSM front cover removal and installation procedure is in the process of being updated.
SSM 517562023-07-03. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2022-2023 Explorer vehicles equipped with a 2.3L engine may exhibit an intermittent malfunction indicator light (MIL) with diagnostic trouble code (DTC) P1026 and/or P1299 present in the powertrain control module (PCM) and an engine over-temperature message displayed on the instrument panel cluster (IPC) after a cold engine start. The vehicle will also exhibit reduced performance when it enters fail safe cooling open loop mode. If the engine is not overheating, clear the DTCs to reset the fail safe cooling open loop mode. Start and idle the engine while viewing coolant flow at the top inner (engine side) degas bottle hose port through the semitransparent top. If there is no coolant flow, replace the L1MZ-8A365-AAD engine-to-degas bottle hose. If if there is any coolant flow, return to Workshop Manual (WSM), Section 303-03A diagnostics.
