- [10167226](https://open.wenmarpro.com/bulletins/10167226), 2019-11-05: 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 accessory protocol interface module \(APIM\) DTC U0198 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.
