Summary
Some 2021 F-150/Mustang Mach-E/Bronco/Edge/Nautilus customers may experience an inoperative FordPass/LincolnWay app, features in FordPass/LincolnWay are not functioning and/or the customer cannot pair the FordPass/LincolnWay mobile app to the vehicle. If the telematics control unit (TCU) on the vehicle does not exhibit any diagnostic trouble codes (DTC), but the customer is running into these app concerns, this may be due to poor cell signal getting to the TCU. The TCU - Provisioning Application on the Ford Diagnosis and Repair System (FDRS) scan tool will provide cell signal strength information that can help to diagnose the source of the poor cell signal. If poor cell signal is found, refer to WSM 415-00 to help identify an antenna concern. Be sure the vehicle is an open environment.

Summary
Some 2021 Bronco vehicles built on or before 14-Sep-2021 may experience a loss of power when driving with various illuminated warning indicators displayed in the instrument panel cluster (IPC). This may be due to an improper seating of the wiring harness push pins to the driveshaft loop which can cause an interference condition between the rear driveshaft and the 14405 harness near the C2370/C350 connector. If suspected, inspect the harness and connector for damage and repair as necessary. Once inspected and/or repaired fully, seat the harness push pins to the driveshaft loop.
