SSM 479712019-06-06. Service bulletin. ENGINE AND ENGINE COOLING. Some 2019 Fusion, 2018-2019 MKZ vehicles equipped with a 2.0L engine may exhibit an auto start/stop, no auto restart concern with diagnostic trouble code (DTC) P164C. A revised crankshaft position (CKP) sensor JX6Z-6C315-B is available. Refer to the Workshop Manual (WSM), Section 303-14B for Fusion and Section 303-14A for MKZ. For claiming, use causal part 6C315 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
TSB19-21582019-06-05. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some 2017-2019 Fusion Hybrid/Fusion Energi/MKZ Hybrid and 2017-2018 C-Max vehicles built on or before 27-Jan-2019 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P013A stored in the powertrain control module (PCM). This may be due to downstream oxygen sensor parameters in the PCM software. To correct the condition, follow the Service Procedure to update the PCM software.
SSM 479222019-05-07. Service bulletin. ENGINE; ENGINE AND ENGINE COOLING. SSM 47922 - Various Vehicles - 2.7L/3.0L EcoBoost Engine - Oil Filter Service Tip When servicing the oil filter on vehicles equipped with a 2.7L or 3.0L EcoBoostengine it is critical to inspect the oil filter housing center stem to verify is not separated or damaged. If the center stem is damaged or separated from the housing this will result in oil flow through the reservoir drain port causing low engine oil pressure and internal engine damage. If the filter housing stem is damaged or separated, the oil filter housing must be replaced. If the center stem is not damaged or separated, the O-ring seals on the stem and housing must be replaced each time the filter is serviced.
SSM 479482019-05-07. Service bulletin. ENGINE. SSM 47948 - 2010-2019 Various Vehicles - Turbocharged Engines - Oil Supply Filter Replacement When Replacing The Turbocharger Or The Turbocharger Oil Supply Tube For 2010-2019 vehicles equipped with turbocharged engines, when diagnosing and/or replacing turbo related concerns, all steps within the Workshop Manual (WSM) procedure must be followed including replacement of all mandatory discarded parts. When specified in the WSM, the turbocharger oil supply filter must be replaced whenever the turbocharger or the turbocharger oil supply tube are replaced. Turbocharger bearing failure may occur if oil starvation occurs due to a restricted filter.
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.
SSM 478242019-04-08. Service bulletin. ELECTRICAL SYSTEM. Some 2015-2017 vehicles may experience a no crank concern due to a security access key table error. When attempting to program keys or perform a parameter reset, the procedure may fail and the Integrated Diagnostic System (IDS) scan tool may display an error 232: Key Table Not Allocated. If this error message is encountered, the Body Control Module (BCM) is internally faulted and requires replacement. For claiming, use causal part 15604 and applicable labor operations in section 10 of the Service Labor Times Standards (SLTS) manual.
SSM 478212019-04-08. Service bulletin. ELECTRICAL SYSTEM. Some 2018-2019 Ford and Lincoln vehicles equipped with a TCU may exhibit inoperative remote features via Ford Pass/Lincoln Way mobile app, incomplete user authorization and/or accessory protocol interface module (APIM) DTC U0198 or no modem electronic serial number (ESN) displayed. To correct this condition prior to programing remove the TCU fuse for 5 minutes then reinstall. Delete all previous session files for the vehicle. Verify that the electronic serial number (ESN) is now displayed. Start a new IDS/FDRS session. Program the TCU to the latest IDS/FDRS version level. Make sure you are connected to the internet before retesting. If the concern is still present, follow normal diagnostics in Workshop Manual(WSM), Section 415-00. Refer to PTS OASIS home page for TCU version identification. For claiming, use causal part 14G229.
SSM 478142019-04-08. Service bulletin. SEATS:FRONT ASSEMBLY:SEAT HEATER/COOLER; SEATS; ELECTRICAL SYSTEM.

DTCs B14BA:13, B1154:4B, and/or B14B9:13 may also be present. This may be due to loose terminal pin fit on the driver seat module (DSM) connector C341D (16 pin). If a loose terminal pin fit condition is found during normal diagnostics per Workshop Manual (WSM), Section 501-10, a new service pigtail connector (part number 3U2Z-14S411-BRAB) is available. Refer to Wiring Diagram, Cell 119 to make sure C341D is a 16 pin connector and not a 20 pin connector. Refer to Wiring Diagram, Cell 5 for the recommended splicing procedures.
SSM 477902019-04-08. Service bulletin. ELECTRICAL SYSTEM; ENGINE. Some 2013-2019 Fusion/MKZ and 2013-2018 C-Max vehicles with 2.0L HEV/PHEV engine may exhibit multiple drivability or electrical concerns with one or more diagnostic trouble codes, being the most common P26C3, P26CA, P26D0, P2800, P2802, U019F and U0284. On Fusion/MKZ inspect connectors C146, C1651, C1812, C168C, C1717 and C134 for signs of water entry or corrosion.

This may be due to inadvertent actuation of the fuel door release button by the customer when exiting the vehicle. If the fuel filler door is not fully closed after a refueling event or the fuel filler door is open from erroneously pressing the fuel door release button, a message displays during the third drive cycle to indicate the fuel filler door is not closed and the DTC sets. Before performing Workshop Manual (WSM) diagnosis, consult the customer about the potential for accidental fuel door actuation and explain the need to fully latch the fuel door after every refueling event. Malfunction Indicator Lamp will turn off after (3) drive cycles with fuel filler door closed.

Some 2017-2019 MKZ vehicles equipped with a 2.0 HEV engine may exhibit a fuel filler door unable to be opened or closed with or without an illuminated malfunction indicator (MIL) and DTC P04B5. This may occur when the fuel door is pressed or obstructed while the fuel door release latch is operating. If the fuel filler door is unable to be closed, a message displays during the third drive cycle and the DTC P04B5 will set. Before performing Workshop Manual (WSM) diagnosis, reset the system by pressing the fuel filler door release switch and wait 12 seconds for reset. The fuel door release latch should be heard when the motor is in motion. Review fuel filler door for locking tab operation. If the fuel filler door is operating properly, it should not be replaced. Advise the customer about the correct operation of the fuel filler door.
SSM 477352019-03-04. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY.

To correct this condition, remove the TCU fuse for 5 minutes prior to programing. Delete all previous session files for the vehicle and do not install the TCU fuse until a new IDS session has been started. Once the new session has been started and the fuse reinstalled, the TCU can be programmed. Make sure you are connected to the internet before retesting. If the concern is still present, follow normal diagnostics in Workshop Manual (WSM), Section 415-00. Refer to PTS OASIS home page for TCU version identification. For claiming, use causal part 14G229.
SSM 476622019-01-07. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. For 2010-2019 vehicles equipped with turbocharged engines, when diagnosing and/or replacing turbo related concerns, all steps within the Workshop Manual (WSM) procedure must be followed including replacement of all mandatory discarded parts. For all turbocharged engine applications, the turbocharger oil supply filter (6C683 gas engine/6L625 connector style or 6A968 diesel engine) must be replaced whenever the turbocharger or the turbocharger oil supply tube are replaced. Turbocharger bearing failure may occur if oil starvation occurs due to a restricted filter.
