WARNING: This page is about a different car, the 2023 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The SCMC (LH rear multi-contour seat module)/SCMD (RH rear multi-contour seat module) controls the operation of the multi-contour control pump which supplies air pressure necessary to be diverted to the applicable air bladders as required for the desired mode(s) of operation.
