SSM 498202021-06-01. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. Some 2017-2021 Ford and Lincoln vehicle owners may experience a condition of missing Authorization, Command and Control, Battery Charging Details or Phone-as-a-Key setup buttons/selections in their FordPass or LincolnWay App. This condition is due to an error within the FordPass or LincolnWay App and not due to a concern on the vehicle. Verify that the customers FordPass or LincolnWay App is at the latest version. Replacement or reprogramming of the telematics control unit (TCU)/gateway module (GWM)/remote function actuator (RFA) will not resolve this condition.

SSM 498032021-06-01. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY. Some 2018-2020 Ford and Lincoln vehicles may exhibit inoperative remote features via the Ford Pass/Lincoln Way mobile app, incomplete user authorization, no modem electronic serial number (ESN) displayed or DTCs U2100 and/or B156D in the telematics control unit (TCU). These symptoms may persist even after performing a TCU software update and/or replacement. To correct this condition, start a new session with the latest version of the appropriate diagnostic scan tool and perform a PMI on the TCU. If issues persist, open a hotline assistance request and include the IDS version (if applicable) used to perform the PMI and the Authorization Status PID value in the TCU datalogger. For claiming use causal part 14G229 and applicable labor times in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 497952021-06-01. Service bulletin. COMMUNICATION:MANUFACTURER TELEMATICS; ELECTRICAL SYSTEM.
