Service bulletin TSB 20-2170

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.

This may be due to condensation from the evaporator drain tube entering the vehicle through the drain tube seal. To correct the condition, follow the Service Procedure steps to install an elbow on the evaporator drain tube to direct the condensation away from the seal.

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.

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 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.
