Component Description

Driver Seat Module (DSM) 

The driver seat control switch and memory power seat motors are hard-wired to the DSM. The DSM controls the operation of the memory power seat. The DSM communicates on the MS-CAN. PMI must be carried out using a scan tool when installing a new DSM.

Memory Set Switch 

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

Seat Control Switch 

The seat control switch is hard-wired to the DSM 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 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.

Front Seat Track Motor 

There are 3 front seat track motors present on power seat tracks. The horizontal (fore/aft) front seat track motor is the only seat track motor which can be serviced separately from the seat track assembly. All other seat track motors (front up/down, rear up/down) are serviced as part of the seat track assembly.

Front Seat Motor Cable 

The horizontal (fore/aft) front seat track motor rotates 2 cables which drive each side of the seat track uniformly. The outboard (long) cable can be serviced separately from the horizontal front seat track motor.
