- [SSM 54720](/bulletins/11031263.md), 2026-04-10, Service bulletin: ELECTRICAL SYSTEM; LANE DEPARTURE: BLIND SPOT DETECTION. Various 2020\-2026 Ford and Lincoln vehicles equipped with blind spot information system \(BLIS\) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster \(IPC\). This may also be accompanied by diagnostic trouble codes \(DTCs\) B118C:11 and/or B118C:15 stored in the driver door module \(DDM\), and/or B118D:11 and/or B118D:15 stored in the passenger door module \(PDM\). This may be due to the wiring connector from the mirror to the BLIS module. If diagnostics lead to an internal mirror wiring harness fault, a new lower level BLIS light pigtail is now released for service. It is not necessary to replace the exterior mirror assembly. Use part number SC3Z\-14A411\-B to resolve the concern.
- [SSM 54589](/bulletins/11029595.md), 2026-03-04, Other: ELECTRICAL SYSTEM.

The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab \> Accessories \> Installation \> Wireless RF Keypad Diagnosis Guide \> PPT C \> Step C2.\<br /\>\<br /\> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k
