- [SSM 54601](/bulletins/11029052.md), 2026-02-27, Service bulletin: ELECTRICAL SYSTEM; STRUCTURE:BODY; UNKNOWN OR OTHER. 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
- [SSM 52243](/bulletins/10250305.md), 2024-02-14, Service bulletin: ENGINE AND ENGINE COOLING. When performing any transmission fluid change or topoff involving Motorcraft® Premium ATF, MERCON® V has replaced all versions of Motorcraft® Premium ATF and can be used going forward. Mixing Motorcraft® Premium ATF and MERCON® V in the same transmission is acceptable. After 31\-Jan\-2024, Motorcraft® Premium ATF will no longer be manufactured and will only be available until inventory depletes.
- [TSB 23\-2098](/bulletins/10234103.md), 2023-05-04, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); HYBRID PROPULSION SYSTEM; ELECTRICAL SYSTEM:PROPULSION SYSTEM:HYBRID MANAGEMENT:POWER CONTROL UNIT/MODULE \(HPCU\). Some 2010\-2012 Fusion hybrid electric vehicles \(HEV\), 2010\-2011 Milan HEV and 2011\-2012 MKZ HEV vehicles may experience reduced electric vehicle operation and increased gasoline engine operation around 10 years of vehicle age and beyond. This may be due to software in the battery energy control module \(BECM\) and the powertrain control module \(PCM\). To correct the condition, follow the Service Procedure to reprogram the BECM and PCM.
- [SSM 48908](/bulletins/10177042.md), 2020-07-07, Service bulletin: EQUIPMENT; ELECTRICAL SYSTEM. Some 2016\-2020 Ford and Lincoln vehicles equipped with a SYNC 3 Touchscreen may experience the volume control unresponsive from the Front Control Interface Module \(FCIM\) and steering volume controls when using Apple Car Play. When the Apple device is removed, volume control is restored. This is due to a concern with the Waze Navigation App software and Apple iOS version. To correct the condition, update the Waze App software and iOS to the latest version available and reboot the customer's Apple device. Perform an ignition cycle and reconnect the Apple device via USB. Open Apple Car Play and confirm volume control is restored. Installing/Updating third party software/applications is not warrantable.
- [SSM 48858](/bulletins/10176123.md), 2020-06-04, Service bulletin: ELECTRICAL SYSTEM. Some 2012\-2020 Ford and Lincoln vehicles equipped with a TCU may exhibit an inoperative remote start with a 'Vehicle Failed To Start' message when using MyFord Mobile/Ford Pass/Lincoln Way mobile applications. The cellular cloud systems will only allow two remote start requests from the MyFord Mobile/Ford Pass/Lincoln Way apps without a vehicle drive event occurring. If a third remote start request is received, a Vehicle Failed To Start message will be displayed quickly in the mobile app. Once the vehicle is driven, the remote start counter is reset and will allow remote start commands to be sent from the mobile app. If the remote start system is not functioning using the key fob, refer to Workshop Manual \(WSM\) Section 303\-06 for further diagnosis.
- [TSB 20\-2142](/bulletins/10174404.md), 2020-05-05, Service bulletin: ELECTRICAL SYSTEM. Some 2010\-2012 Fusion hybrid electric vehicles \(HEV\), 2010\-2011 Milan HEV and 2011\-2012 MKZ HEV vehicles may experience reduced electric vehicle operation and increased gasoline engine operation around 10 years of vehicle age and beyond. This may be due to software in the battery energy control module \(BECM\) and the powertrain control module \(PCM\). To correct the condition, follow the Service Procedure to reprogram the BECM and PCM.
- [SSM 48238](/bulletins/10167224.md), 2019-11-05, Service bulletin: ENGINE AND ENGINE COOLING. Some 2010\-2012 Fusion hybrid electric vehicle \(HEV\), 2010\-2011 Milan HEV and 2011\-2012 MKZ HEV vehicles may experience reduced electric vehicle operation and increased gasoline engine operation. Do not attempt repairs at this time. Engineering is investigating, monitor OASIS for updates.

The Powertrain Control/Emissions Diagnosis \(PC/ED\) manual has been revised for diagnosing electronic throttle bodies \(ETBs\). The ETC\_ACT and ETC\_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes \(DTCs\) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.
