Component Description

Driver Seat Module (DSM)

The driver seat control switch and memory power seat motors are hard-wired to the DSM (Driver Seat Module). The DSM (Driver Seat Module) controls the operation of the memory power seat. The DSM (Driver Seat Module) communicates on the MS-CAN (Medium Speed Controller Area Network). PMI (Programmable Module Installation) must be carried out using a scan tool when installing a new DSM (Driver Seat Module).

Memory Set Switch

The memory set switch assembly contains 3 momentary contact switches. It is hard-wired to the DSM (Driver Seat Module) and is used to recall 1 of 3 memory positions stored in the DSM (Driver Seat Module).

Seat Control Switch

The seat control switch is hard-wired to the DSM (Driver Seat Module) which controls seat operation.

Seat Track

The seat track contains 3 bi-directional motors which are integral to the seat track assembly. Each seat track motor contains a Hall-effect sensor which provides seat track position information to the DSM (Driver Seat Module) for setting/obtaining desired preset seat memory positions. The seat track motors move the power seat forward/backward and up/down depending on the polarity of voltage supplied from the DSM (Driver Seat Module).
