coming from the module, replace the Memory Seat/
Mirror Module.
²If P9 low current battery is present at (cavity 5)
referenced to ground Z1 (cavity 1) of the seat switch,
verify the presence of the P9 voltage at the switch
outputs. If there is no output voltage from the
switch, replace the switch.
²If P9 voltage is present at the output of the
switch, but there is no reaction from the memory
seat/mirror module, verify that the P9 voltage is
present at the appropriate 21-way connector pins
into the module. If the P9 voltage is not present at
the 21-way connector, repair or replace the seat wir-
ing harness. If the verification check of the seat wir-
ing harness is correct, replace the control module.
(2) If the control module does not respond with a
relay click to a specific seat switch when actuated,
verify the continuity of the particular circuit between
the seat switch and the Memory Seat/Mirror Module.
If the P9 voltage is present at the correct input of the
21-way connector of the module when the switch is
actuated, but there is no response by the module,
replace the Memory Seat/Mirror Module.
(3) If the Memory Seat/Mirror Module responds
with a relay click when a seat switch is actuated for
a given direction, but there is no reaction from a seat
or recliner motor relating to that switch input, dis-
connect the 10-way connector from the control mod-
ule. Jumper the battery and ground from cavities 8
and 7 of the seat harness 10-way connector to the
proper cavities for the seat or recliner motor in ques-
tion and direction of travel desired. If the motor oper-
ates, replace the control module. If the motor does
not operate, verify continuity of the wiring into the
motor 2-way connector. Repair or replace the wiring
as necessary. If the wiring has continuity, and the
motor will not operate when fed directly, replace the
track assembly, since the motor/transmission combi-
nations are not designed to be serviced on an individ-
ual basis.
SEAT AND RECLINER POSITION SENSING
Seat and recliner position sense ground reference
circuit P28 BR/RD feed is from the memory seat/mir-
ror module (cavity 10) 21-way connector to each of
the position sense connectors.
Seat and recliner position sense +5 volt feed circuit
P29 BR/WT feed is from the memory seat/mirror
module (cavity 20) 21-way connector to each of the
position sense connectors.
To test for the presence of a sense voltage, a volt
meter must be used as follows:
²Connect the negative probe to the P28 circuit
(cavity 10) of the 21-way connector.
²Connect the positive probe to the P29 circuit
(cavity 20) of the 21-way connector and verify a volt-age reading between 3.5 and 5 volts when a seat or
recliner switch is activated.An internal timer in
the Memory Seat/Mirror Module (MSM Module)
regulates the length of time this voltage stays
active i.e., 3 seconds from the time that the
switch was activated, unless the switch is held
or while the transmission is out of PARK.If the
voltage is less than 3.5, there is a fault in the system
that is drawing it down. To troubleshoot this circuit,
disconnect the 25-way connector from the MSM Mod-
ule (this removes all of the vehicle mirror circuitry).
If the voltage is still less than 3.5, disconnect each of
the position sense connectors from each of the
motors. If the voltage remains less than 3.5, replace
the MSM Module. If the voltage increases when a
motor is disconnected from the system, determine if
the fault is in the wiring or the motor assembly.
Repair or replace the wire harness assembly as
needed. If the fault is in the motor position sensing
potentiometer, replace the track assembly.
²The potentiometers built onto the motor end-bell
provide voltages to the MSM Module through the
21-way connector, which change as follows, corre-
sponding to the given seat actuations. Refer to Seat
Actuations Table.
SERVICE PROCEDURES
REMOTE KEYLESS ENTRY (RKE) DATA LINK
The memory seat/mirror module interfaces with
the RKE via a serial data link (single wire). The pro-
gramming sequence to relate an RKE transmitter to
the chosen seat, recliner and side view mirror posi-
tions consists of the following steps:
(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
1or2.
(4) Press momentarily and release a LOCK button
on an RKE transmitter.
(5) To program the second driver's position, follow
the previous sequence with a second transmitter.
(6) To recall either of the programmed positions
with an RKE transmitter, press momentarily and
release an UNLOCK button on one of the pro-
grammed RKE transmitters.An unprogrammed
RKE transmitter will have no effect on the sys-
tem.
(7) The RKE receiver uses the serial data link to
notify the module of a request from a programmed
transmitter, that an UNLOCK button has been
pressed. This UNLOCK request (from a transmitter
associated with either switch 1 or 2) will activate the

DESCRIPTION AND OPERATION
INTRODUCTION
Chrysler wiring diagrams are designed to provide
information regarding the vehicles wiring content. In
order to effectively use Chrysler wiring diagrams to
diagnose and repair a Chrysler vehicle, it is impor-
tant to understand all of their features and charac-
teristics.
Diagrams are arranged such that the power (B+)
side of the circuit is placed near the top of the page,
and the ground (B-) side of the circuit is placed near
the bottom of the page.
All switches, components, and modules are shown
in the at rest position with the doors closed and the
key removed from the ignition.Components are shown two ways. A solid line
around a component indicates that the component is
complete. A dashed line around a component indi-
cates that the component being shown is not com-
plete. Incomplete components have a reference
number to indicate the page where the component is
shown complete.
It is important to realize that no attempt is made
on the diagrams to represent components and wiring
as they appear on the vehicle. For example, a short
piece of wire is treated the same as a long one. In
addition, switches and other components are shown
as simply as possible, with regard to function only.
NS/GS8W-01 GENERAL INFORMATION 8W - 01 - 1
SECTION IDENTIFICATION
The wiring diagrams are grouped into individual
sections. If a component is most likely found in a par-
ticular group, it will be shown complete (all wires,
connectors, and pins) within that group. For exam-
ple, the Auto Shutdown Relay is most likely to be
found in Group 30, so it is shown there complete. It
can, however, be shown partially in another group if
it contains some associated wiring.
SYMBOLS
International symbols are used throughout the wir-
ing diagrams. These symbols are consistent with
those being used around the world.
