SSM 493882021-01-05. Service bulletin. EQUIPMENT; ENGINE AND ENGINE COOLING:ENGINE:DIESEL; POWER TRAIN; ELECTRICAL SYSTEM. 2021 F-150/Explorer/Aviator/Police Interceptor Utility vehicles without a diesel engine and/or without a 10R80 MHT transmission have a new PCM-Transmission Accelerated Main Control Break In routine added to the Diagnosis and Testing Section of the WSM. This new routine uses the Ford diagnostic scan tool to cycle the shift solenoids and clutch control valves to free them from contamination that may be sticking the valves. Refer to WSM, Section 307-01.
SSM 493772021-01-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM. Some 2020-2021 Explorer/Aviator vehicles equipped with a 3.0L EcoBoost engine and built on or before 01-Dec-2020 may exhibit inoperative air conditioning, an illuminated malfunction indicator lamp, and/or an illuminated powertrain malfunction (wrench) indicator with various diagnostic trouble codes present and a blown fuse F14. This may be due to wiring harness 14290 chaffing on the A/C compressor pulley. If chaffing is present, repair as necessary. Refer to Wiring Diagram, Cell 005 for repair procedures. Make sure that the wiring harness retainer is fully seated in the back side of the bracket on the A/C compressor to keep the harness away from the compressor pulley.
