SSM 515362023-05-04. Service bulletin. STRUCTURE. For 2000-2024 Ford and Lincoln vehicles, swapping a module from a vehicle for diagnosis purposes is likely to cause errors and is not recommended. It is also not recommended to order a replacement module using a vehicle identification number (VIN) from a different vehicle. Most modules on these affected vehicles are VIN/vehicle specific and hardware variations between modules do exist. Swapping a module from a vehicle or ordering a module using a different vehicle/VIN can cause ineffective repairs and additional vehicle down time. Make sure all appropriate Workshop Manual (WSM) procedures are followed when diagnosing the condition prior to all module replacements and only order modules using the correct VIN.
SSM 515422023-05-04. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN. Some 2020-2023 F-150 and 2021-2023 Bronco vehicles equipped with a 2.7L or 3.0L EcoBoost engine may exhibit a ticking/tapping or rattle type noise from the top front cover area of the engine on initial start-up after a cold soak of 6 hours or more that may last for 2-5 seconds. This may be due to a stuck internal component of the variable cam timing (VCT) unit. To correct the condition, replace all 4 of the VCT units following Workshop Manual (WSM), Section 303-01. For claiming, use causal part 6C525 and applicable labor operations in Section 6 of the Service Labor Time Standards (SLTS) Manual. If labor times are not available, claim M-time.
SSM 515332023-05-04. Service bulletin. VISIBILITY:REARVIEW MIRRORS/DEVICES. Some 2021-2023 Bronco vehicles may exhibit a diagnostic trouble code (DTC) B15F1:15 code stored in memory of the passenger door module (PDM). This code was intended for a right mirror indicator light emitting diode (LED) feature on vehicles and currently is not used. This code may be due to PDM module software. If the PDM module exhibits DTC B15F1:15, the DTC should be ignored.
TSB 23-21172023-05-04. Service bulletin. STRUCTURE; VISIBILITY:REAR WINDOW WIPER/WASHER. Some 2021-2022 Bronco vehicles may exhibit paint damage on the rear quarter panel due to contact with the rear window assembly (D-pillar). This may be due to an oversized washer being used during production. To correct the condition, repair the paint damage to the rear quarter panel and replace the rear window assembly.
SSM 515312023-05-04. Service bulletin. POWER TRAIN. Some 2020-2023 Explorer/Aviator/Transit, 2021-2023 F-150/Bronco, 2022-2023 Expedition/Navigator/Mustang and 2023 F-250/F-350 Super Duty vehicles may exhibit harsh/delayed engagement and/or harsh/delayed shift concerns. These may be addressed with the powertrain control module (PCM)/transmission control module (TCM) Transmission Accelerated Main Control Break In Routine and/or a main control overhaul. Refer to Workshop Manual (WSM), Section 307-01, DTC Chart if DTCs are present and/or Diagnosis By Symptom to identify the clutch(s) to be cycled. Cycling the shift solenoids and clutch control valves to remove contamination must be performed along with an adaptive drive cycle before attempting repair.

SSM 514192023-04-04. Service bulletin. POWER TRAIN. Some 2017-2023 Ford and Lincoln vehicles equipped with a 10R60/10R80/10R80 MHT/10R100 transmission may exhibit a whine noise at idle and/or while driving. This may be identified as coming from the bellhousing and the front of the transmission fluid pan. The whine noise may become louder when the transmission is at operating temperature and may increase with engine revolutions per minute (RPM) in the park (P) position. A small amount of whine noise is considered to be characteristic of the 10R60/10R80/10R80 MHT/10R100 transmissions due to the offset gear drivetrain in the front support and has no effect on durability.
SSM 514152023-04-04. Service bulletin. ENGINE AND ENGINE COOLING. Customers who neutral (4-wheel flat) tow a 2021-2022 Bronco equipped with a 2.7L engine or a 2022-2023 Bronco Raptor may report an inconsistent brake assist when a supplemental braking system has been installed. This may result from supplemental brake system set-up that does not account for the vehicles anti-lock brake (ABS) module entering sleep mode after a pre-determined period of time following vehicle shut-down. This functionality was necessary to prevent a battery drain from occurring. Enhanced software has been developed to keep the ABS module in a consistent sleep state when the vehicle enters neutral tow mode.
