Component Description: DSM
WARNING: This page is about a different car, the 2017 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The driver seat control switch and power memory seat motors are hard-wired to the DSM. The DSM controls the operation of the power memory seat. The DSM communicates on the MS-CAN. PMI is required when a new DSM is installed. The DSM hard stop/soft stops must be set/reset any time a new DSM, driver seat track or driver seat backrest is installed.
