Service bulletin SSM 46888

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.

NHTSA's summary

Some 2017 Explorer vehicles equipped with a 110V power inverter may exhibit a high pitched buzzing or ringing noise from the passenger side front interior area while the engine is running. To isolate the noise to the power inverter, remove fuse 56 from the battery junction box with the engine running. Make sure there is nothing plugged into the 110V outlet during the test. If the noise is no longer present with the fuse removed, the noise is isolated to the inverter and no other components should be replaced. Replacement of the inverter may not resolve the noise. Engineering is aware of the concern and is investigating. The noise does not affect the operation of the power inverter. Please submit a Global Concern Report and continue to monitor OASIS for updates.

SSM 546012026-02-27. Service bulletin. Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab > Accessories > Installation > Wireless RF Keypad Diagnosis Guide > PPT C > Step C2.<br /><br /> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k
TSB 25-25702025-12-01. Service bulletin. This article supersedes TSB 24-2165 to update the TSB Service Procedure. Some vehicles listed in the Model statement above may exhibit various SYNC performance related concerns including but not limited to: Display operation concerns Navigation inoperative Voice recognition concerns Phone connection issues Dropped phone connections Applink related performance Travel Link not present or showing incorrect traffic Slow system response NOTE: Ford has found some of the APIMs replaced and returned for inspection contained an outdated software level and the APIM did not require replacement. The customer concern may have been resolved by updating the APIM with latest level of software. The SYNC 3 universal thumb drive will be able to update the APIM software without the use of a scan tool and does not require the process to be monitored. Ford will be monitoring APIM replacements to confirm TSB directed software updates have been performed.

SSM 509752022-08-02. Service bulletin. Some 2017-2022 Ford/Lincoln customers may experience a notification in the FordPass®/LincolnWay® app indicating Vehicle Has Entered Deep Sleep Mode. This occurs when the vehicle has not been started for 14 consecutive days, battery voltage is at/below 9.5 volts or the body control module (BCM) 12 volt battery state of charge (SOC) drops below 50%. A warning may also set if the telematic control unit (TCU) has received an over the air update. The TCU powers down all communication when in this mode and app features are disabled. Manually start the vehicle to wake if from mode. More information is located in the app under: Account > Help > search 'Deep Sleep' in the entry box. If the condition remains, check the BCM 12v SOC. If the SOC does not change after charging the battery or after BMS reset is performed, continue with normal battery and/or BMS sensor diagnostics.
SSM 508042022-06-01. Service bulletin. Some 2013-2023 Ford or Lincoln vehicles with modems activated through FordPass or LincolnWay may experience 12 volt battery drain symptoms when the customer uses non-Ford/Lincoln phone applications as an alternate channel to access vehicle commands such as door lock/unlock, remote start, vehicle location, etc. The battery drain may be caused by excessive calls for data through the vehicle network keeping it in an activated state. Recommend that the customer uninstall the app to ensure this is not contributing to battery symptoms experienced. Advise the customer that unaffiliated third-party app developers do not work directly with Ford to adhere to security, vehicle communication, and privacy requirements.
