Power Seat Control Module: Description and Operation
DRIVER SEAT MODULE - MEMORY SEAT
The power driver seat, power outside rear view mirrors, power adjustable pedals and adjustable steering column are controlled by the driver seat module
(DSM) only when the vehicle is equipped with the programmable/recall memory option. The DSM is located on the driver seat track.
This system allows automatic positioning of the driver seat to 2 programmable positions.
The memory seat system consists of the following components:
-
DSM

Driver memory seat control switch
-

Two personalized seat positions may be programmed into the memory seat system. A memory seat position may be set by first positioning the driver seat
using the driver power seat switch and depressing the memory set switch. Memory seat position 1 or 2 must be selected within 5 seconds to set a
personalized seat position. If position 1 or 2 is not selected within 5 seconds, the operation is aborted. This operation also aborts if any input is received
from the driver power seat switch, the power mirror switch, the adjustable pedal switch, the power adjustable steering column switch or if the memory set
switch is depressed again during the 5-second limit. The personalized memory seat positions are recalled using the memory switch positions 1 and 2 or
with the remote keyless entry transmitter.
A programmed seat position can only be recalled when the transmission selector is in PARK or NEUTRAL with the ignition switch in the RUN position.
A position may be programmed at any time.
For information on the DSM, refer to Body Control Systems (Multifunction Electronic Control Module).
