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.
