# Service bulletin SSM 49217

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.

- Type: Service bulletin
- NHTSA id: 10180674
- Published by NHTSA: 2020\-10\-06
- Manufacturer's number: SSM 49217
- Manufacturer's date: 2020\-09\-29
- NHTSA component: EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM:ADAS:BLINDSPOT:SOFTWARE

## NHTSA's summary

Some 2015\-2020 F\-150/Mustang, 2016\-2020 Edge, 2016\-2018 MKX and 2019\-2020 Nautilus vehicles built on or before 18\-Jan\-2020 may exhibit a mirror click and/or ratcheting noise when using memory functions or easy entry/exit function. This may be due to the software in the driver door module \(DDM\) and passenger door module \(PDM\). To correct the condition, reprogram the DDM and PDM with the latest software level of the appropriate Ford diagnostic scan tool. For claiming use causal part 14B291 and applicable labor times in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.

## Other bulletins for the same vehicles and component

- [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.
