Hard wired circuitry connects the heated seat sys-
tem components to each other through the electrical
system of the vehicle. These circuits may be con-
nected to each other, to the vehicle electrical system
and to the heated seat system components through
the use of a combination of soldered splices and
splice block connectors. Refer to the appropriate wir-
ing information for complete circuit schematic or con-
nector pin-out information.
OPERATION
The heated seat system components operate on
battery current received through a fuse in the Inte-
grated Power Module (IPM) on a fused ignition
switch output (run) circuit from the Body Control
Module (BCM). The system will only operate when
the ignition switch is in the On position. The heated
seat system will be turned Off automatically when-
ever the ignition switch is turned to any position
except On. Also, the heated seat system will not oper-
ate when the surface temperature of the seat cushion
cover at either heated seat sensor is above the
designed temperature set points of the system.
DIAGNOSIS AND TESTING

mation.
HEATED SEAT SWITCH
DESCRIPTION
The heated seat switches are mounted in the
instrument panel center bezel (Fig. 2). The two three-
position rocker-type switches, one switch for each
front seat, are incorporated into one large switch
assembly that also includes the hazard, rear window
wiper and washer switches. Each heated seat switch
provides a resistor multiplexed signal to its respec-
tive Heated Seat Module (HSM) through separate
hard wired circuits. Each switch has an Off, Low,
and High position so that both the driver and the
front seat passenger can select a preferred seat heat-
ing mode. Each switch has two Light-Emitting
Diodes (LED) which light to indicate that the heater
for the seat is turned on.
The heated seat switches and their LEDs cannot
be repaired. If either switch or LED is faulty or dam-
aged, the entire switch assembly must be replaced.

LAMPS/LIGHTING - EXTERIOR
DESCRIPTION
LAMP SYSTEMS
Lighting circuits are protected by fuses. Lighting
circuits require an overload protected power and high
side drivers source, ON/OFF device, lamps and body
grounds to operate properly. Plastic lamps require a
wire in the harness to supply body ground to the
lamp socket. Replace sockets and bulbs that are cor-
roded.
Some of the interior and exterior lighting functions
are governed by the Body Control Module (BCM).
The headlamp, dome, and the door ajar switches pro-
vide signals to the BCM. The BCM in turn sends a
Programmable Communication Interface (PCI) bus
message to the Front Control Module (FCM) to
enable the necessary drivers to set the required illu-
mination configuration.
Wire connectors can make intermittent contact or
become corroded. Before coupling wire connectors,
inspect the terminals inside the connector. Male ter-
minals should not be bent or disengaged from the
insulator. Female terminals should not be sprung
open or disengaged from the insulator. Bent and
sprung terminals can be repaired using needle nose
pliers and pick tool. Corroded terminals appear
chalky or green. Corroded terminals should be
replaced to avoid recurrence of the problem symp-
toms.
Begin electrical system failure diagnosis by testing
related fuses in the fuse block and intelligent power
module. Verify that bulbs are in good condition and
test continuity of the circuit ground. Refer to the
appropriate wiring information.
AUTOMATIC HEADLAMP SYSTEM
The Automatic Headlamp system turns the instru-
mentation and exterior illumination lamps ON when
the ambient light levels are Night and the engine
RPM is 450 or above, and OFF when light levels are
Day.
DAYTIME RUNNING LAMPS
Operating the high-beam headlamps at reduced
power provides daytime running lamps, which are
required on all new Canadian vehicles. Daytime run-
ning lamps are functional when 450 rpm's are
reached.
HEADLAMPS ON WITH WINDSHIELD WIPERS
For vehicles equipped with the Automatic Head-
lamp System, the instrumentation and exterior illu-
mination lamps will be turned ON when the
headlamp switch is in the AUTO position, RPM >450 and the windshield wipers have been in the
intermittent, low or high mode of operation for more
than ten seconds. When the windshield wipers are
turned OFF the Body Control Module will determine
if the instrumentation and exterior illumination
lamps should remain ON base upon the current
ambient light level.
HEADLAMP SYSTEM
The configuration of the headlamp system of head-
lamps, park lamps and fog lamps is determined by
the BCM. The BCM determines the lighting configu-
ration as a result of the inputs from the ignition
switch, headlamp switch and multi-function switch. A
PCI bus is transmitted from the BCM to the FCM to
enable the necessary drivers to set the illumination
configuration. Four wires are connected between the
headlamp switch and the BCM. The first wire con-
tains information regarding the position of the head-
lamp switch (Off, Automatic Headlamps, Automatic
Headlamp switch fog, Park with Fog, Head, or Head
with Fog Lamps). The second wire contains informa-
tion regarding the position of the dimmer switch
(Dome Lamp, Daytime Brightness, Dimming Level or
Off). The third wire is a dedicated signal return
(ground) wire. The fourth wire provides power to the
front fog lamp indicator.
HEADLAMP TIME DELAY SYSTEM
The headlamp time delay system is controlled by
the Body Control Module (BCM) via a PCI bus mes-
sage transmitted by the BCM to the FCM to turn off
the headlamps.
OPERATION
AUTOMATIC HEADLAMP SYSTEM
Automatic headlamps are controlled by the Body
Control Module (BCM). With the headlamp switch in
the AUTO position, the BCM will control the head-
lamp, parking, side marker, tail and instrumentation
lamps based on ambient light levels. Ambient light
levels are monitored by the BCM using the Day/
Night signal and Electrochromatic Mirror (ECM)
present from the Compass Mini Trip (CMTC) located
on the front windshield in front of the rear view mir-
ror ECM. Ambient light readings are averaged to
limit cycling the lamps ON and OFF when passing
through areas with varying light levels. The auto-
matic headlamps will only function when the engine
is running with RPM > 450. When the headlamp
switch is in the AUTO position (Automatic mode), the
Headlamp Time Delay system will function when the
ignition switch is placed in any position other than
run/start.

POWER MIRRORS
DESCRIPTION
If equipped with power mirrors, the control switch
is located on the instrument panel to the left of the
headlamp switch.
OPERATION
The power mirrors are connected to battery feed at
all times. Each mirror head contains two electric
motors, two drive mechanisms, an electric heating
element, and the mirror glass. If the vehicle is
equipped with the optional memory system, the
driver side mirror head also contains both a horizon-
tal and a vertical motor position sensor. One motor
and drive controls mirror up-and-down movement,
and the other controls right-and-left movement.An optional driver side outside electrochromic mir-
ror is able to automatically change its reflectance
level. This mirror is controlled by the circuitry of the
automatic day/night inside rear view mirror. A thin
layer of electrochromic material between two pieces
of conductive glass make up the face of the mirror.
Two photocell sensors on the inside rear view mirror
are used to monitor light levels and adjust the reflec-
tance of both the inside and driver side outside mir-
rors. This change in reflectance helps to reduce the
glare of headlamps approaching the vehicle from the
rear. (Refer to 8 - ELECTRICAL/POWER MIRRORS/
AUTOMATIC DAY / NIGHT MIRROR - DESCRIP-
TION) for more information on this system.
The motors which operate the mirrors are part of
the mirror assembly and cannot be serviced sepa-
rately.

AUTOMATIC DAY / NIGHT
MIRROR
DESCRIPTION
An automatic dimming inside day/night rear view
mirror and an automatic dimming driver side outside
rear view mirror are available factory-installed
options on this model. Following is a general descrip-
tion of this optional equipment.
The automatic day/night mirror is able to automat-
ically change its reflectance. A thin layer of electro-
chromic material between two pieces of conductive
glass make up the face of the mirror. Two photocell
sensors are used to monitor light levels and adjust
the reflectance of the mirror to reduce the glare of
headlamps approaching the vehicle from the rear.
For removal procedures, (Refer to 23 - BODY/IN-
TERIOR/REAR VIEW MIRROR - REMOVAL).
OPERATION
The ambient photocell sensor faces forward, to
detect the outside light levels. A second sensor faces
rearward to detect the light level received through
the vehicles back window. When the difference
between the two light levels becomes too great (the
light level received at the rear of the mirror is much
higher than that at the front of the mirror), the mir-
ror begins to darken.
The mirror switch allows the driver a manual con-
trol of whether the automatic dimming feature is
operational. When AUTO is selected a small Light-
Emitting Diode (LED), to the right of the mirror
switch, is illuminated. The automatic dimming fea-
ture will only operate when the ignition switch is in
the On position. The mirror also senses the backup
lamp circuit, and will automatically disable its self-
dimming feature whenever the transmission gear
selector is in the Reverse position.
NOTE: The mirror always defaults to an ON state
upon ignition.
The driver side automatic dimming mirror is stan-
dard with the automatic dimming inside mirror. The
signal to control the dimming of that mirror is gen-
erated by the automatic day/night inside rear view
mirror circuitry. That signal is then delivered to the
driver side outside rear view mirror on a hard wired
circuit.
The automatic day/night mirror cannot be
repaired. If faulty or damaged, the entire inside rear
view mirror assembly must be replaced.
DIAGNOSIS AND TESTING
AUTOMATIC DAY / NIGHT MIRROR
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
(1) Check the fuse in the intelligent power module.
If OK, go to Step 2. If not OK, repair the shorted cir-
cuit or component as required and replace the faulty
fuse.
(2) Turn the ignition switch to the On position.
Check for battery voltage at the fuse in the intelli-
gent power module. If OK, go to Step 3. If not OK,
repair the open circuit to the ignition switch as
required.
(3) Unplug the wire harness connector from the
automatic day/night mirror. Check for battery voltage
at the fused ignition switch output circuit cavity of
the automatic day/night mirror wire harness connec-
tor. If OK, go to Step 4. If not OK, repair the open
circuit to the junction block as required.
(4) Turn the ignition switch to the Off position.
Check for continuity between the ground circuit cav-
ity of the automatic day/night mirror wire harness
connector and a good ground. There should be conti-
nuity. If OK, go to Step 5. If not OK, repair the cir-
cuit to ground as required.
(5) Turn the ignition switch to the On position. Set
the parking brake. Place the transmission gear selec-
tor lever in the Reverse position. Check for battery
voltage at the backup lamp switch output circuit cav-
ity of the automatic day/night mirror wire harness
connector. If voltage is present, reinstall the auto-
matic day/night mirror wire harness connector and
go to Step 6. If not OK, repair the open circuit as
required.
(6) Place the transmission gear selector lever in
the Neutral position. Place the automatic day/night
mirror switch in the On (LED in the switch is
lighted) position. Cover the forward facing ambient
photocell sensor to keep out any ambient light.
NOTE: The ambient photocell sensor must be cov-
ered completely, so that no light reaches the sen-
sor. Use a finger pressed tightly against the sensor,
or cover the sensor completely with electrical tape.
(7) Shine a light into the rearward facing head-
lamp photocell sensor. The automatic day/night mir-
ror should darken. The automatic day/night mirror
should darken within 2 minutes if testing for the
first time. For immediate response, turn the vehicle
8N - 28 POWER MIRRORSRS

OFF and back ON with the forward-facing light sen-
sor still covered. This defeats the day-detect logic. If
OK, go to Step 8. If not OK, replace the faulty mirror
unit.
(8) With the mirror darkened, place the transmis-
sion gear selector lever in the Reverse position. The
automatic day/night mirror should return to its nor-
mal reflectance. If not OK, replace the faulty mirror
unit.
Bench testing both mirrors can be done, of care is
exercised. For an inside mirror, the pin closest to he
mount is 12V (+), the next is 12V (-). The third is
reverse override. The fourth is outside mirror (+), and
the fifth is outside mirror (-).Do not apply 12 volts to
the fourth and fifth pins.With 12 volts on pins 1 and
2, the mirror can be tested by blocking the rear sensor
and shining a light into the forward sensor. For an out-
side mirror, there is a 2±pin connector. Applying 1.2
volts will cause the mirror to dim. If the mirror does not
dim, the entire glass assembly can be replaced just as it
is when the glass is broken.
WARNING: Do not apply 12 volts to the outside mir-
ror. Damage to the mirror will result.
POWER FOLDAWAY MIRROR
SWITCH - EXPORT
DESCRIPTION
These vehicles may be equipped with Power Fold-
away Mirrors. This feature allows both the driver
and passenger side view mirrors to fold inward
(retract) on demand. The vehicle has an additional
switch located on the steering column that controls
the folding function of the mirror assembly (Fig. 2).
The fold-away side view mirror is attached to the
vehicle's door in the same manner as mirrors without
the fold-away option. The fold-away mirrors unique
option is the internal motor which allows the mirrors to
fold inward on demand. The fold-away mirror motor is
not serviceable separately and if a motor is found to be
faulty the entire side view mirror must be replaced.
OPERATION
When the mirror retract switch is depressed, both
of the side view mirrors will fold inward, Thus mak-
ing the overall width of the vehicle the smallest pos-
sible. This can be helpful were parking space is a
absolute minimum.
When the driver's door is opened, only the driver's
door mirror will unfold. If the passenger door is
opened, both mirrors will unfold.
The power fold away mirror system consists of the fol-
lowing components: mirror switch, side view mirror,relay, wires and fuse. Refer to the appropriate wiring
information. The wiring information includes wiring
diagrams, proper wire and connector repair procedures,
details of wire harness routing and retention, connector
pin-out information and location views for the various
wire harness connectors, splices and grounds.

and the driver outside mirror position for two driv-
ers. On vehicles equipped with a factory radio, the
memory system is also able to store and recall radio
station presets for two drivers. The memory system
also will store and recall the last station listened to
for each driver, even if it is not one of the preset sta-
tions.
The memory system will automatically return to
its preset settings when the corresponding numbered
button of the memory switch is depressed, or when
the doors are unlocked using the corresponding
Remote Keyless Entry (RKE) transmitter. A customer
programmable feature of the memory system allows
the RKE recall of memory features to be disabled, if
desired. This programmable feature is internal in the
Electronic Vehicle Information Center (EVIC) mod-
ule, which is located in the overhead console.
A Memory Seat Mirror Module (MSMM) is used to
control and integrate the many electronic functions
and features included in the memory seat and mirror
systems.

²Radio receiver (if PCI data bus capable)
Certain functions of the memory system rely upon
resources shared with other electronic modules in the
vehicle over the Programmable Communications
Interface (PCI) data bus network. Initial diagnosis of
these electronic modules or the PCI data bus network
requires the use of a DRBIIItor equivalent scan tool
and the proper Diagnostic Procedures information. If
this method does not prove conclusive, the proper
wiring schematics and the service manual diagnostic
information are required.

OPERATION
POWER SEAT SYSTEM
The power seat system receives battery current
through fuse #22 in the Integrated Power Module
(IPM) and a circuit breaker under the front seats,
regardless of the ignition switch position.
When a power seat switch control knob or knobs
are actuated, a battery feed and a ground path are
applied through the switch contacts to the appropri-
ate power seat track adjuster motor. The selected
adjuster motor operates to move the seat track
through its drive unit in the selected direction until
the switch is released, or until the travel limit of the
seat track is reached. When the switch is moved in
the opposite direction, the battery feed and ground
path to the motor are reversed through the switch
contacts. This causes the adjuster motor to run in the
opposite direction.
No power seat switch should be held applied in any
direction after the seat track has reached its travel
limit. The power seat adjuster motor each contain a
