# Service bulletin TSB 20\-2142

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.

- Type: Service bulletin
- NHTSA id: 10174404
- Published by NHTSA: 2020\-05\-05
- Manufacturer's number: TSB 20\-2142
- Manufacturer's date: 2020\-04\-27
- NHTSA component: ELECTRICAL SYSTEM

## NHTSA's summary

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 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

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.
- [16\-0066](/bulletins/10183767.md), 2020-12-07, Service bulletin: ELECTRICAL SYSTEM. Some 2012\-2016 vehicles equipped with a touchscreen navigation system and the language set to Arabic may exhibit a blank screen. This may be the result of the ribbon cables not being fully seated inside the front display interface module \(FDIM\) or an improper software configuration of the FDIM.
- [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.
- [SSM 48123](/bulletins/10164497.md), 2019-09-06, Service bulletin: ELECTRICAL SYSTEM. For Ford and Lincoln vehicles that require positive or negative battery terminal replacement, it is not necessary to replace the complete battery cable harness \(14300 and 14301\) for this concern. Positive battery cable clamp BT4Z\-14450\-AA and negative battery cable clamp BT4Z\-14450\-BA are available for this type of repair. Do not cut or shorten the battery cable, instead carefully remove the affected battery cable clamp and clean the cable end as necessary to preserve wire length. Some rework may be necessary for some vehicle environments. Bend the new positive battery cable clamp as needed and crimp it to the existing battery cable. Make sure to use heat shrink tubing over the battery cable to battery cable clamp connection. Obtain the heat shrink tube locally.
