GENERAL INFORMATION
INTRODUCTION
The Memory Heated Seat and Mirror Module
(MHSMM) is located underneath the front of the
driver seat. It is mounted unto the bottom of the seat
by two screws. The connections to the system are
through a seat wiring harness that interfaces with
all of the components within the seat structure. The
MHSMM system allows the driver to adjust the seat,
both driver and passenger side mirrors, and the radio
stations to his/her preference and store them in
memory. There are two memory locations available
for two driver positions to be stored. The module will
also allow either of the two positions to be recalled
upon request.
The MHSMM reads all seat switch inputs and
operates the seat motors according to which switch is
being actuated. The MHSMM monitors position sens-
ing potentiometers (mounted on the motors) for seat
track positioning.
The MHSMM uses solid state drivers (electronic
switches) to control motor activation for both driver
and passenger side mirrors. Each mirror has vertical
and horizontal motors, that contain potentiometers
used to located the actual mirror position for recall
purposes. Normal electrical operation of the mirrors
is accomplished by actuating the power mirror switch
and doesn’t require the use of the module.
The MHSMM monitors the memory switches and
has the capability to store desired positions in mem-
ory in response to a valid input sequence. Refer to
Memory Selector Switches (1, 2, and S) and Remote
Keyless Entry (RKE). The memory heated seat and
mirror module will activate the seat and mirror
motors in response to a recall request from an indi-
vidual memory switch. The positioning of the motors
is determined by the potentiometer values stored in
memory.
The module operates the seat motors through
relays: four dedicated to track horizontal forward/
rearward,
front
vertical
up/down,
rear
vertical
up/down, and recliner forward/rearward. A fifth relay
controls the direction of operation of these motors.
GLIDE FEATURE
The MHSMM shall incorporate a seat glide fea-
ture. This feature will allow easier entry and exit to
the vehicle by moving the seat rearward a short dis-
tance when the operator leaves the vehicle and
returning the seat to its original position when the
vehicle operator returns and turns the ignition ON or
extends their seat belt.
DESCRIPTION AND OPERATION
MEMORY SELECTOR SWITCH
The memory selector switches are mounted on the
cushion cover side shield of the driver eat within
easy reach of the driver (Fig. 1). They provide a
means to set and recall either of the two positions of
seat and recliner, and the side view mirror as chosen
by the driver.
The proper procedure of setting and recalling a
memory position using the memory switches is as fol-
lows:

POWER SEATS

(1) Adjust the seat, recliner and side view mirrors
to the desired position.
(2) Press momentarily and release memory switch
S.
(3) Press momentarily and release memory switch
1 or 2.
(4) To program the second driver’s position, repeat
the above procedure using the remaining memory
switch.
(5) To recall either of the programmed positions
momentarily press and release either memory selec-
tor switch 1 or 2.
DIAGNOSIS AND TESTING
GLIDE FEATURE
If seat isn’t sliding forward properly:
(1) First use the DRB scan tool to check whether
glide feature is enabled or not. Enable glide feature if
disabled, and go to Step 2.
(2) Turn the ignition ON and then back OFF.
Remove the key. If seat glides rearward, reinsert key
and turn to ON position. If seat doesn’t glide for-
ward, go to Step 3, otherwise the problem has been
fixed. If Learn Guard Bands test has been run and
problem persists, then replace MHSMM.
(3) Now run Learn Guard Bands Diagnostic test as
shown in this section, and go through Step 2 again.
SERVICE PROCEDURES
REMOTE KEYLESS ENTRY (RKE)
The MHSMM interfaces with the RKE vial the PCI
bus. The proper procedure of setting and recalling a
memory position using the RKE is as follows:
(1) Press memory switch 1 and release to recall
memory position 1.
(2) Adjust the seat, recliner and side view mirrors
to the desired position.
(3) Press momentarily and release memory switch
S.
(4) Press momentarily and release memory switch
1 or 2. Do NOT press any switch for 10 seconds.
(5) Press momentarily and release the UNLOCK
button on one of the RKE transmitters.
(6) Set radio station presets.
(7) To program the second driver’s position, repeat
the above procedure using memory switch 2. The sec-
ond RKE transmitter can be programmed in the
fashion.
(8) To recall either of the programmed positions
momentarily press and release either memory selec-
tor switch 1 or 2. If using RKE, just press and
release the UNLOCK button on the proper transmit-
ter for either position 1 or 2.
(9) A recall is possible any time the vehicle trans-
mission is in PARK. This condition is monitored by
the Body Control Module (BCM).
NOTE: The module will abort a recall if the trans-
mission is moved out of park or if any seat move-
ment is activated whether manually or by memory
recall.
