Service bulletin 20N04 S2

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.

SSM 524762024-05-03. Service bulletin. All accessory stick-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated (wired) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System (DPES); dealership management can authorize users. The authorized user must go to FMCDealer.com > Parts and Service > Parts Product Line Information > Keys/Entry Devices > Aftermarket Keyless Entry Keypad Code Access. Follow the instructions on the screen to obtain the master code for the accessory keypad.
22M03 S12024-05-02. Service bulletin. Certain 2017-2020 Model Year Continental and Super Duty, 2018-2020 Navigator, 2020 Aviator, and 2020 Explorer Vehicles Replace Front and/or Side Cameras if Foggy
SSM 523142024-03-20. Service bulletin. During service and repair requiring removal and replacement of a crankshaft bolt and/or crankshaft damper, achieving proper torque of the crankshaft pulley bolt is critical. Incorrect torque may allow the bolt to loosen resulting in the timing gear breaking and engine damage. Replacement of the bolt is critical to the repair and accurately following the installation procedure in the Workshop Manual (WSM) Section, 303-01 is extremely important. The bolt torque procedure can be found in the crankshaft front seal removal and installation procedure or in the engine assembly procedure.
SSM 519472023-10-06. Service bulletin. Some 2015-2019 F-Super Duty and 2015-2020 F-150/Mustang vehicles may require replacement of the powertrain control module (PCM) for various reasons. While performing a programmable module installation (PMI) using the Integrated Diagnostic Service (IDS) scan tool, an error message may state: Configuration Failed, Would You Like To Retry? This may be due to improper module replacement steps. Make sure that the original module is installed in the vehicle, delete the vehicle session, then start a new vehicle session. Once the session starts, run the PCM PMI and install the new PCM only when the scan tool instructs. Finish the PMI by following the prompts given by IDS. If the original PCM is not available, it is possible to configure the module by running as-built programming on the PCM. When IDS asks to obtain part numbers or configuration data, select configuration data.
SSM 519372023-10-05. Service bulletin. Some vehicles equipped with power folding mirrors may exhibit power folding mirrors that are inoperative or exhibit a clicking sound. This may be due to the mirrors being manually folded in, during transportation, going through a car wash, bumped in a parking lot, or found during pre-delivery inspection (PDI). Prior to the replacement of any components, attempt to synchronize the mirrors by following the Power Mirrors Synchronization procedure. Refer to Workshop Manual (WSM) Section 501-09 Rear View Mirrors - General Procedures - Power Mirrors Synchronization.
SSM 518542023-09-04. Service bulletin. Various 2013-2019 vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P264F after powertrain control module (PCM) replacement. This DTC indicates that the engine serial number (ESN) must be programmed into the PCM. The ESN is located on PTS > Diagnostics tab > HVBoM > Features > Engine Serial Number. Once the ESN is obtained from the historical vehicle bill of materials (HvBOM), it can be programmed into the PCM using the appropriate Ford diagnostic scan tool. Navigate to the toolbox tab> powertrain menu> Service Functions> ESN.

SAN-Vol1 I12023-08-16. Service bulletin. The Service Awareness Newsletter is an informal communication that contains information that may not be presently available in a TSB, SSM, GSB, or other electronic communication. This article includes information on warranty, technical service tips and other service information.
SSM 518292023-08-14. Service bulletin. Some F-Super Duty and F-150 vehicles equipped with trailer tow mirror may exhibit various exterior rear view mirror functional concerns that require replacement after diagnosis. To properly determine if the defect is warrantable, cleaning and close inspection of the affected mirror may be required. To aid in proper warranty determination, the Rear-View Mirror Analysis general service bulletin (GSB) has been updated with a detailed cleaning procedure that should be followed prior to any inspection. New labor operations (17682ZZ or 17682ZZT) have been created that covers the cleaning and inspection process and may be used even if condition of failure is non-warrantable. Ford has inspected numerous returned parts and determined many cases are caused by damage which is unwarrantable and may be subject to chargeback. Refer to the latest version of the GSB on OASIS.
