Service bulletin SSM 50153

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.

NHTSA's summary

Some 2020-2021 Navigator and Aviator vehicles may exhibit a condition when setting the climate control temperature where the degrees do not appear in the SYNC screen. This may be due to the SYNC software installed in the accessory protocol interface module (APIM). Engineering is currently developing a software update that is expected in January 2022. Once the software update is available, contact the customer and schedule a follow-up appointment for repair in February 2022. Monitor OASIS for updates.

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.
SSM 503752021-12-27. Service bulletin. Some 2016-2021 Ford and Lincoln vehicles equipped with SYNC 3 may exhibit a condition where the navigation voice prompts are inoperative after a SYNC map update. This may be due to an incomplete installation of the SYNC map software. If possible, using the original USB that installed the update, reperform the update and verify the navigation voice prompts have returned. Multiple reboots are expected when this update is being performed. Verify the Installation Is Complete message displays in the touch screen. If the original USB is not available, go to website https://syncnavigation.com/ford/home or https://syncnavigation.com/lincoln/home to download the files once more for the affected vehicle. For further map update support, reference the FAQ section on these websites.

This may be due to the software in the SCMJ. To correct the condition, connect a battery charger and reprogram the SCMJ using the latest software level of the appropriate Ford diagnostic scan tool. Then open the liftgate, and perform the SCMJ - Power Fold Seat Module (SCMJ) Learn Seat Procedure. For claiming, use causal part 14F042 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
