# Service bulletin SSM 50271

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.

- Type: Service bulletin
- NHTSA id: 10203861
- Published by NHTSA: 2021\-12\-07
- Manufacturer's number: SSM 50271
- Manufacturer's date: 2021\-11\-08
- NHTSA component: COMMUNICATION:MANUFACTURER TELEMATICS; UNKNOWN OR OTHER

## NHTSA's 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.
