Some 2018 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, remove the TCU fuse for 5 minutes then reinstall. 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.
