tions. When the memory system is in “set” mode a
chime will be generated by the BCM.
DIAGNOSIS AND TESTING
MEMORY SWITCH
(1) Remove the memory switch from the drivers
door panel (Refer to 8 - ELECTRICAL/POWER
SEATS/MEMORY SET SWITCH - REMOVAL).
(2) Using an ohmmeter, check the continuity of the
memory select switch MUX circuit between the C2
wire harness connector for the Body Control Module
(BCM) and the wire harness connector for the mem-
ory switch. There should be continuity. If OK, go to
Step 3. If not OK, repair the open or shorted MUX
circuit as required.
(3) Using an ohmmeter, check the continuity of the
memory select switch return circuit between the C2
wire harness connector for the BCM and the wire
harness connector for the memory switch. There
should be continuity. If OK, go to Step 4. If not OK,
repair the open or shorted return circuit as required.
(4) Using an ohmmeter, test the resistances of the
memory switch, refer to the MEMORY SWITCH
TEST TABLE. If OK, (Refer to 8 - ELECTRICAL/
POWER SEATS - DIAGNOSIS AND TESTING -
MEMORY SYSTEM). If not OK, replace the memory
switch, (Refer to 8 - ELECTRICAL/POWER SEATS/
MEMORY SET SWITCH - REMOVAL).

REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the front door trim panel switch bezel
from the driver side front door. Using a thin flat-
bladed pry tool, gently pry the switch bezel away
from the drivers door trim panel.
(3) Disconnect the memory switch wire harness
connector from the memory switch.
(4) Remove the two screws that secure the memory
switch to the back of the driver side front door trim
panel switch bezel.
(5) Remove the memory switch.
INSTALLATION
(1) Position the memory switch and install and
tighten the two screws that secure the memory
switch to the back of the driver side front door trim
panel switch bezel. Tighten the screws to 2.2 N·m (20
in. lbs.).
(2) Reconnect the memory switch wire harness
connector to the memory switch.
(3) Install the trim panel switch bezel onto the
driver side front door.
(4) Reconnect the battery negative cable.
POWER SEAT TRACK
DESCRIPTION
The power seat option includes an electrically oper-
ated power seat track located under the front seat. If
equipped with Memory System, the front power seat
track on the driver side of the vehicle also provides
the mounting location for the Memory Seat/Mirror
Module (MSMM). The power seat circuit breakers are
mounted on the rear of the power seat track, just
behind the seat rear trim panel. The lower half of the
power seat track is secured to the floor panel via four
studs and nuts that must be accessed from the
underside of the vehicle. Four bolts secure the bot-
tom of the seat cushion pan to the upper half of the
power seat track unit. Four additional bolts secure
the seat back frame to the power seat track unit.
The eight-way power seat track unit includes four
reversible electric motors that are secured to the
upper half of the track unit. Each motor moves the
seat adjuster through a combination of worm-drive
gearboxes and screw-type drive units. Each of the
four power seat track motors used on models
equipped with the optional memory system incorpo-
rate a position potentiometer integral to the motor
assembly, which electronically monitors the motor
position. This enables the memory system to function
by referencing the motor positions programmed into
the memory seat/mirror module.
