Service bulletin SSM 50855

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Some 2021-2023 Ford and Lincoln vehicles equipped with SYNC 4 may exhibit the navigation feature in the center display screen only displaying imperial units and not being able to change to metric. This may be due to the software level of the SYNC module (APIM). This issue does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that engineering is currently working on a solution for this condition and will be released via Ford Power-Up software updates delivered over-the-air (OTA) expected in September 2023. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update in September 2023. Monitor OASIS for additional information.
SSM 51004	2022-08-30. Service bulletin.

SSM 50829	2022-06-17. Service bulletin. 2021-2022 various Ford and Lincoln vehicles may exhibit an erroneous diagnostic trouble code (DTC) U1A01:93 stored in the telematics control unit (TCU). This may be due to various software parameters within the TCU. If this DTC is identified during normal diagnostics, but the vehicle does not exhibit any customer concerns around the TCU operation, clear this DTC and no further repairs are recommended. If the DTC returns after being cleared or if the vehicle exhibits connectivity concerns with the TCU, continue with normal Workshop Manual (WSM) diagnostics. If set erroneously, this DTC does not cause any observable concerns or warning messages and does not affect vehicle performance or durability. Ford is developing a software update which will be delivered to the vehicle via an over-the-air (OTA) TCU update in July 2022 to prevent this DTC from setting erroneously.

Some 2020-2022 F-Super Duty/Explorer/Aviator and 2021-2022 F-150 vehicles may exhibit a Front Camera Fault, Lane Keeping Fault, and/or Collison Warning Not Available message with various diagnostic trouble codes (DTC) stored in the image processing module A (IPMA). If programming fails or Ford Diagnosis and Repair System (FDRS) states a file failed to flash after replacing the IPMA or reprogramming IPMA software, test the battery using any approved Rotunda tool including the GR-190, GRX-3590, and DCA-8000. Fully recharge or replace the battery according to results of the tool. Set the battery charger to maintain battery voltage between 12.6 and 13.6 volts during the entire programming procedure. The IPMA programming procedure may take several hours to complete due to the size of the software files required.
