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 487572020-05-04. Service bulletin. ELECTRICAL SYSTEM. Some customers may experience a notification in the FordPass and/or LincolnWay apps that indicates their vehicle has entered "deep sleep mode". This mode is enabled due to the vehicle not being started for 14 consecutive days or battery voltage is at/or below 9.5 volts. Some 2020 models will also set a warning if the telematic control unit (TCU) has received an automatic over the air update. The purpose of deep sleep mode is to conserve battery voltage. When deep sleep mode is enabled, the TCU is powered down and all communication with the FordPass and/or LincolnWay apps are disabled. To wake the vehicle from deep sleep mode, manually start the vehicle. More deep sleep mode information can be found in the FordPass or LincolnWay apps under: More > Guides > click in search entry box > type "deep sleep" and click on "Ask".

This tester will help reduce the potential for misdiagnosis and unnecessary compressor replacement. Refer to the Rotunda catalog for a video and user manual which provide detailed operating instructions.
SSM 481302019-09-06. Service bulletin. VISIBILITY:GLASS, SIDE/REAR; VISIBILITY. Some 2010-2020 vehicles may exhibit distorted glass with a subtle orange peel pattern or streaking etched into the surface. This is caused by hydrofluoric acid which is used in some car wash solutions as a cleaning agent. Hydrofluoric acid can attack the glass and cause visual distortion and/or discoloration on the outer surface which cannot be removed by further cleaning. If this type of distortion is found, inspect the area of the glass that is covered by the cowl and/or molding. The portion of glass that is covered by the cowl or molding will not be affected by the acid. Hydrofluoric acid damage is not a defect in material or workmanship and is not a warrantable condition.
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.

If this error message is encountered, the body control module (BCM) is internally damaged and requires replacement. The BCM should only be replaced for this condition when the 232 key table error message is present. If the 232 key table error is not present, follow normal diagnostics for the no crank condition. For claiming, use causal part 15604 and applicable labor operations in section 10 of the Service Labor Times Standards (SLTS) manual.
TSB 19-21352019-07-03. Service bulletin. POWER TRAIN; VEHICLE SPEED CONTROL:CRUISE CONTROL. Some 2015-2019 Mustang GT350/GT350R vehicles may exhibit a hesitation or surge in the vehicle with no diagnostic trouble codes (DTCs) present. This may be accompanied by an inoperative cruise control system. This may be due to a transmission output shaft flange nut that has come loose, allowing the output shaft tone ring to move in relation to the output shaft causing an erroneous signal. To resolve the condition, follow the Service Procedure steps to replace the output shaft flange nut.
SSM 479912019-06-07. Service bulletin. POWER TRAIN; POWER TRAIN:DRIVELINE. Some 2015-2019 Mustangs may exhibit a driveline vibration after removal and installation of the drive pinion flange. This may be due to improper removal and installation of the drive pinion flange. It is critical to reinstall the drive pinion flange in the same orientation on the drive pinion stem as it was before it was removed. Mark the drive pinion flange and the drive pinion stem before removing the flange to make sure that it is reinstalled on the stem in the same orientation as it was before removal. Refer to Workshop Manual (WSM), Section 205-02.
SSM 479762019-06-07. Service bulletin. POWER TRAIN. On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi-Purpose Grease Spray XL-5-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop Manual (WSM), Section 307-01.
SSM 479782019-06-06. Service bulletin. TIRES. Some 2015-2019 Mustang GT/GT350/GT350R Coupe vehicles equipped with Michelin Pilot Sport Cup 2 tires may exhibit tires which appear to have worn treads even when the tires are new or have low miles. This may be due to the fact that these tires come from the factory with a tread design which has shallower tread depth than most tires. There are also fewer grooves molded into the surface of the tire, with some areas of the tire showing no tread at all. Before condemning these tires as excessively worn, ensure that you are familiar with how these tires appear when new.
SSM 479672019-06-06. Service bulletin. 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.

This noise may sound similar to a front engine accessory drive (FEAD) chirp noise. This may be due to the primary timing chain tensioner oil pressure relief valve. To correct the condition, replace the primary timing chain tensioners. Follow the Service Procedure.
TSB19-21442019-06-05. Service bulletin. ENGINE. Some 2018-2019 F-150 and Mustang vehicles equipped with a 5.0L engine may exhibit a light to moderate knocking type noise at idle (600-700 RPM) that is sometimes described as a quiet diesel type sound. The noise is usually more prominent on the passenger side of the vehicle toward the rear of the engine. As the engine comes up to operating temperature, the noise level increases slightly. This noise is not detrimental to engine function and has no short or long term effects on engine durability. This an operating characteristic of the 5.0L engine and no repairs should be attempted. Refer to the Service Procedure
