Seat Control Switch - Driver

For vehicles without multi-contour seats, the driver seat control switch is hard-wired to the DSM, which controls seat operation. The seat control switch contains normally closed contacts (which are grounded) through the DSM. When a specific adjustment position is selected, an individual circuit is switched to voltage.

If equipped with multi-contour seats, the driver seat control switch communicates seat commands over a LIN to the DSM, which controls seat movements. The driver seat control switch is hard-wired to the SCMG to control the multi-contour seat massage/adjust features. The driver seat control switch contains a 5 position momentary contact switch which provides an analog signal (stepped resistance) to the SCMG.
