Seat Control Switch - With Multi-Contour Seats
WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The driver seat control switch is hard-wired to the DSM, which controls seat operation. When a specific seat adjustment position is selected, an individual circuit is switched to voltage.
The driver and passenger seat control switches each contain a 5 position momentary contact switch which provides an analog signal (stepped resistance) to the SCMG or SCMH. The resistance range for each multi-contour button is as follows:
| Multi-Contour Switch | Resistance |
|---|---|
| Select | 26 to 54 ohms |
| Down | 113 to 125 ohms |
| Up | 196 to 221 ohms |
| Deflate | 317 to 351 ohms |
| Inflate | 483 to 533 ohms |
| No switch active | 573 to 634 ohms |
