TSB 20-21702020-06-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some 2018-2020 F-150/Expedition/Navigator/F-Super Duty vehicles built on 31-Aug-2018 and through 02-Feb-2020 may exhibit a water leak on the right front floor during and/or after the air conditioning (A/C) is used. This may be due to condensation from the evaporator drain tube entering the vehicle through the drain tube seal. To correct the condition, follow the Service Procedure steps to install an elbow on the evaporator drain tube to direct the condensation away from the seal.
SSM 487772020-05-04. Service bulletin. EQUIPMENT:ELECTRICAL; EXTERIOR LIGHTING. Some 2020 F-Super Duty vehicles may exhibit a condition where the turn signals flash fast after removal of the factory pick up box and tail lamps for flatbed installation. To prevent the turn signals from flashing fast, the BCM will need to be configured using the FDRS scan tool. Start a vehicle session in FDRS using the vehicles VIN and go to the toolbox tab. The BCM will have an application labeled Turn Signal Lamp Configuration. Download and run this application to configure the turn signals.
SSM 487172020-05-04. Service bulletin. EQUIPMENT:ELECTRICAL. Some 2020 F-Super Duty vehicles equipped with the Blind Spot Information System (BLIS) and Cross Traffic Alert (CTA) may require the removal of the factory equipped tail lamps to accommodate the use of aftermarket equipment. Once the tail lamps are removed, this may result in BLIS and CTA warning indicators illuminated in the instrument panel cluster (IPC). To clear these warning indicators, the BLIS and CTA systems will need to be disabled using the FDRS scan tool. Start a vehicle session in FDRS using the vehicles VIN and go to the toolbox tab. The BCM will have an application labeled Disable/Enable Blind Spot Information System. Download and run this application to enable or disable the BLIS And CTA systems.
SSM 484442020-02-04. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM. Some 2020 Ford and Lincoln vehicles may exhibit a symptom of no ability to schedule a remote start event using the FordPass or Lincolnway app. If only the scheduling portion of the remote start system is not functioning, no repair attempts should be made to correct this condition. If the remote start system is not functioning using the key fob and/or the on-demand remote start function from FordPass or Lincolnway application, refer to Workshop Manual (WSM), Section 303-06 for further diagnosis. Do not attempt repairs at this time. Engineering is currently investigating, monitor OASIS for updates.
