SSM 490322020-08-04. Service bulletin. BACK OVER PREVENTION; ELECTRICAL SYSTEM; EQUIPMENT. Some 2020 Corsair/Explorer/Super Duty vehicles built on or before 27-May-2020 and not equipped with a 360-camera system may exhibit various rear parking aid camera concerns such as poor image quality, flickering and/or completely inoperative. If a vehicle exhibits any of these conditions, replace the rear parking aid camera. Refer to Workshop Manual (WSM), Section 413-13.

SSM 489082020-07-07. 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.

The final stage manufacturer is responsible for verifying that the lane keeping or departure system camera sensor is properly calibrated within Ford specifications once vehicles are completed. Calibrating the lane keeping or departure system utilizes the Ford FDRS scan tool to calibrate the front view camera. Refer to Workshop Manual (WSM) section 419-07. Do not submit a claim for this condition.
SSM 488592020-06-04. Service bulletin. TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS; ELECTRICAL SYSTEM.

The customer may indicate that they cannot monitor the trailer TPMS through the IPC when a configured trailer is connected. If the 'Trailer Tire Pressure' selection is not available in the IPC, the IPC will need to be reconfigured to make the Trailer Tire Pressure selection available. Using the latest version of the FDRS scan tool, reconfigure the IPC. For claiming use causal part 10849 and refer to Section 10 of the Service Labor Time Standards (SLTS) Manual.

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".
