# Service bulletin SSM 50251

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 2017\-2020 Ford and Lincoln vehicles equipped with a TCU may exhibit inoperative remote features via Ford Pass/Lincoln Way mobile app, incomplete user authorization and/or no modem electronic serial number \(ESN\) displayed. To correct this condition prior to programming, remove the TCU fuse for 5 minutes then reinstall. Delete all previous session files for the vehicle. Verify that the electronic serial number \(ESN\) is now displayed. Start a new IDS/FDRS session. Program the TCU to the latest IDS/FDRS version level. Make sure you are connected to the internet before retesting. If the concern is still present, follow normal diagnostics in Workshop Manual\(WSM\), Section 415\-00. Refer to PTS OASIS home page for TCU version identification. For claiming, use causal part 14G229 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.
