SSM 546012026-02-27. 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

TSB 22-22302022-06-27. Service bulletin. ELECTRICAL SYSTEM:PROPULSION SYSTEM:HYBRID MANAGEMENT:POWER CONTROL UNIT/MODULE (HPCU):SOFTWARE; UNKNOWN OR OTHER. Some 2013-2017 C-MAX Energi, 2013-2018 Focus battery electric vehicle (BEV), 2013-2020 Fusion plug-in hybrid electric vehicle (PHEV), 2015-2017 MKZ/MKZ Hybrid/MKC, 2016-2017 MKX and 2017 Continental vehicles equipped with SYNC screens 8 inch or larger may be unable to complete modem authorization after 3G to 4G modem upgrade was performed. No Authorization Popup will be displayed on SYNC infotainment screen during the Authorization process. The vehicle may also not have proper functionality of remote app features such as remote start, and return odometer and fuel information to the app. This may be due to the SYNC software. To correct the condition, follow the Service Procedure to toggle Valet Mode.
SSM 508042022-06-01. Service bulletin. ELECTRICAL SYSTEM. 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.
TSB 22-21622022-05-12. Service bulletin. ENGINE; ELECTRICAL SYSTEM. Some 2014-2017 C-MAX Energi, 2014-2020 Fusion plug-in hybrid electric vehicle (PHEV), 2015-2017 MKZ/MKZ Hybrid/MKC, 2016-2017 MKX, 2016-2018 Focus battery electric vehicle (BEV) and 2017 Continental vehicles equipped with SYNC screens 8 inch or larger may be unable to complete modem authorization after 3G to 4G modem upgrade was performed. No Authorization Popup displayed on SYNC infotainment screen during the Authorization process. This may be due to the Sync Software. To correct the condition, follow the Service Procedure to toggle Valet Mode.
Service2021-12-20. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT; STEERING; VISIBILITY; STRUCTURE. Online automotive service information system for March 2016
SSM 488582020-06-04. 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 486192020-04-02. Service bulletin. UNKNOWN OR OTHER; ELECTRICAL SYSTEM. SSM 48619 - Various Vehicles - Perimeter Alarm Armed And Original Vehicle Keys Cannot Be Accessed to Enter Vehicle - CAN Protection Strategy Some 2013-2016 Model Year Vehicles may exhibit a concern in which the Perimeter Alarm is active and the original keys cannot be accessed to disable the perimeter alarm. This concern would most often occur when a customer loses keys and the dealership is attempting to program new keys to the vehicle. The Workshop Manual (WSM), Section 419-01A Perimeter Anti-Theft Alarm - System Operation and Component Description has been updated to inform of the Controller Area Network (CAN) Protection Strategy. Follow the procedure outlined to prevent replacement of the Body Control Module (BCM) on CAN Protection Strategy equipped vehicles when original keys are lost and perimeter alarm is active. Refer to the WSM for further detail on the CAN Protection Strategy. Lost keys and replacement of BCM for lost keys is non-warrantable.
SSM 483012019-12-05. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM. Some 20132017 C-MAX Energi, 20172018 C-MAX Hybrid, 20132020 Fusion Energi and 2017-2020 Fusion/MKZ Hybrid vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with any of the following diagnostic trouble codes (DTCs): P0496, P1450, P04ED, P04EF, P04EE, P2450, P2451. When performing pinpoint test (PPT) HX in the Powertrain Controls and Emission Diagnosis (PC/ED) Manual for the referenced DTCs, incorrect results may be obtained due to an internal powertrain control module (PCM) software conflict. In order to make sure the PPT provides accurate results, immediately prior to step HX22, make sure the fuel door is fully latched and then press the fuel door release button. Keep the door open while completing HX22, then fully latch again, prior to continuing the remainder of testing
SSM 481232019-09-06. 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.
SSM 478502019-05-07. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some 2013-2019 vehicles equipped with a EVDC air conditioning (A/C) compressor may exhibit poor A/C performance/improper climate function and/or a diagnostic trouble code (DTC) P06A0 in the powertrain control module (PCM). To support the proper diagnosis of this compressor, the EVDC control valve tester has been developed and is available from Rotunda (339-EVDC100). A tester has been provided to each U.S. dealership free of charge with shipments completed 19-Apr-2019 (reference EFC07013 on FMCDealer.com). This tester will help reduce the potential for misdiagnosis and unnecessary compressor replacement. Make sure that this tester is used for warranty repairs and document the test results in the Technician Comments field. Refer to the Rotunda catalog for a video and user manual which provide detailed operating instructions.
