SSM 52476	2024-05-03. 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.
SSM 52314	2024-03-20. 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 51947	2023-10-06. 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.
