UNIVERSAL TRANSMITTER
DESCRIPTION
On some RS models a Universal Transmitter trans-
ceiver is standard factory-installed equipment. The
universal transmitter transceiver is integral to the
Electronic Vehicle Information Center (EVIC) and the
Compass Mini-Trip Computer (CMTC), which is
located in the overhead console. The only visible com-
ponent of the universal transmitter are the three
transmitter push buttons centered between the mod-
RSMESSAGE SYSTEMS8M-9
ELECTRONIC VEHICLE INFO CENTER (Continued)
ProCarManuals.com

ules push buttons located just rearward of the dis-
play screen in the overhead console. The three
universal transmitter push buttons are identified
with one, two or three light indicators so that they be
easily identified by sight or by feel.
Each of the three universal transmitter push but-
tons controls an independent radio transmitter chan-
nel. Each of these three channels can be trained to
transmit a different radio frequency signal for the
remote operation of garage door openers, motorized
gate openers, home or office lighting, security sys-
tems or just about any other device that can be
equipped with a radio receiver in the 286 to 399
MegaHertz (MHz) frequency range for remote opera-
tion. The universal transmitter is capable of operat-
ing systems using either rolling code or non-rolling
code technology.
The electronics module displays messages and a
small house-shaped icon with one, two or three dots
corresponding to the three transmitter buttons to
indicate the status of the universal transmitter. The
EVIC messages are:
²Cleared Channels- Indicates that all of the
transmitter codes stored in the universal transmitter
have been successfully cleared.
²Training- Indicates that the universal trans-
mitter is in its transmitter learning mode.
²Trained- Indicates that the universal transmit-
ter has successfully acquired a new transmitter code.
²Transmit- Indicates that a trained universal
transmitter button has been depressed and that the
universal transmitter is transmitting.
The universal transmitter cannot be repaired, and
is available for service only as a unit with the EVIC
or CMTC modules. If any of these components is
faulty or damaged, the complete EVIC or CMTC
module must be replaced.
OPERATION
The universal transmitter operates on a non-
switched source of battery current so the unit will
remain functional, regardless of the ignition switch
position. For more information on the features, pro-
gramming procedures and operation of the universal
transmitter, see the owner's manual in the vehicle
glove box.
DIAGNOSIS AND TESTING - UNIVERSAL
TRANSMITTER
If the universal transmitter is inoperative, but the
Electronic Vehicle Information Center (EVIC) or
Compass Mini-Trip Computer is operating normally,
see the owner's manual in the vehicle glove box for
instructions on training the universal transmitter.
Retrain the universal transmitter with a known good
transmitter as instructed in the owner's manual andtest the universal transmitter operation again. If the
unit is still inoperative, replace the faulty universal
transmitter and EVIC/CMTC module as a unit. If
both the universal transmitter and the EVIC/CMTC
module are inoperative, refer toOverhead Console
Diagnosis and Testingearlier in this group for fur-
ther diagnosis. For complete circuit diagrams, refer
toOverhead Consolein Wiring Diagrams.
AMBIENT TEMP SENSOR
DESCRIPTION
Ambient air temperature is monitored by the over-
head console through ambient temperature messages
received from the Front Control Module (FCM) over
the Programmable Communications Interface (PCI)
J1850 data bus circuit. The FCM receives a hard
wired input from the ambient temperature sensor.
The ambient temperature sensor is a variable resis-
tor mounted to a bracket that is secured with a screw
to the right side of the headlamp mounting module
grille opening, behind the radiator grille and in front
of the engine compartment.
Refer toFront Control Modulein Electronic
Control Modules. For complete circuit diagrams, refer
to the appropriate wiring information. The ambient
temperature sensor cannot be adjusted or repaired
and, if faulty or damaged, it must be replaced.
OPERATION
The ambient temperature sensor is a variable
resistor that operates on a five-volt reference signal
sent to it by the Front Control Module. The resis-
tance in the sensor changes as temperature changes,
changing the temperature sensor signal circuit volt-
age to the Front Control Module. Based upon the
resistance in the sensor, the Front Control Module
senses a specific voltage on the temperature sensor
signal circuit, which it is programmed to correspond
to a specific temperature. The Front Control Module
then sends the proper ambient temperature mes-
sages to the EVIC, CMTC over the PCI J1850 data
bus.
The thermometer function is supported by the
ambient temperature sensor, a wiring circuit, the
Front Control Module, the Programmable Communi-
cations Interface (PCI) data bus, and a portion of the
Electronics module. If any portion of the ambient
temperature sensor circuit fails, the Front Control
Module will self-diagnose the circuit.
The ambient temperature sensor circuit can also be
diagnosed by referring toDiagnosis and Testing -
Ambient Temperature Sensor, and Diagnosis
and Testing - Ambient Temperature Sensor Cir-
cuit. If the temperature sensor and circuit are con-

equipped with actuator motors to lock or unlock the
latch mechanisms. The door lock actuator motor is
not serviced separately from the door latch, except
for the sliding door(s).
AUTOMATIC DOOR LOCK
The vehicle comes with two options for power door
locks:
²Rolling automatic lock (ENABLE), doors auto-
matically lock at approximately at 25.7 Km/h (16
mph).
²No rolling automatic lock (DISABLE), doors do
not automatically lock when the vehicle is moving.
AUTOMATIC DOOR UNLOCK
The doors will unlock automatically on vehicles
equipped with power door locks if:
²Auto door locks feature is enabled and automatic
unlock is enabled.²The transmission was in gear and speed is above
zero.
²The transmission in park or neutral and speed
is zero.
²Any door (excluding liftgate) opens.
DOOR LOCK INHIBIT

REMOTE KEYLESS ENTRY SYSTEM
The key fob transmitter (Fig. 1) has six buttons.
Three of them, LOCK, UNLOCK, and PANIC, are
used to actuate parts of, and program the Remote
Keyless Entry (RKE) system via the customer pro-
gramming mode. It is not necessary to use the
PANIC button with the DRB IIItscan tool mode of
programming.
OPERATION
POWER DOOR LOCK SYSTEM
The Body Control Module (BCM) locks or unlocks
the doors when an actuation input signal from a door
lock switch or Remote Keyless Entry Module (RKE)
is received. The BCM turns on the output drivers
and provides a voltage level to the door lock motor
for a specified time. The BCM locks the doors auto-
matically when the vehicle is driven beyond the
speed of 25.7 Km/h (16 mph). The rolling door lock
feature can be disabled if desired. All doors and lift-
gate can be locked or unlocked using mechanical but-
ton or key cylinder methods (Liftgate cylinder does
not lock/unlock vehicle. It only unlocks the liftgate).
AUTOMATIC DOOR LOCKS
The BCM is equipped with a disable feature to
stop the speed sensitive automatic door locks from
functioning. The DISABLE feature can be switched
ON or OFF as desired. When the system is DIS-
ABLED the door locks will operate normally, but will
not lock automatically when the vehicle is rolling.
When the door locks are ENABLED the door locks
will automatically lock when the vehicle is moving at
about 25.7 Km/h (16 mph). All doors are closed, the
PCM has set the ªOK TO LOCKº bit, and doors were
not previously locked.
DOOR LOCK INHIBIT
If the key is in the ignition, in any position, and
either front door is ajar, all power door lock function-
ing shall be disabled when activating either door lock
switch. Also, if the Vehicle Theft Alarm (VTA) is
armed, the door lock switch ªUNLOCKº feature will
be disabled until the vehicle is disarmed. Pressing
the RKE lock/unlock button under these conditions
will result in a normal lock/unlock activation.
After the key is removed from the Ignition Switch,
or the doors are closed, the power door locks will
operate normally.
CENTRAL LOCKING
If equipped with Vehicle Theft Security System
(VTSS), all the doors can be locked with the key by
using any of the door lock cylinders. Turning the key
to the LOCK position will lock all the doors.
When either of the front key cylinder switches is
detected active, the BCM will activate the illumi-
nated entry feature and the individual front doors
will become mechanically unlocked. To central unlock
all doors, a second transition from OFF to UNLOCK
has to occur within 2 seconds of the first complete
UNLOCK cycle.
To central unlock the driver door, turn the key to
the rear of the vehicle. This indicates an unlock sig-
nal to the BCM. For the passenger door, turn the key
toward the front of the vehicle. When either key cyl-
inder switch is detected as active, the BCM will acti-
vate the illuminated entry feature. The individual
doors will become mechanically unlocked.
To central lock the vehicle, the driver door lock cyl-
inder is turned toward the front of the vehicle. The
passenger door lock cylinder is turned toward the
rear of the vehicle. When a lock input from either
key cylinder is detected as active, the BCM will can-
cel the illuminated entry feature and perform the
central lock operation.

DOOR LOCK CIRCUIT PROTECTION
The BCM controls the door lock output drivers. If
the door lock switch is actuated continuously for
more than one second the BCM will turn the output
driver OFF (the BCM would consider the switch
stuck). The lock motors are protected with Positive
Temperature Coefficient (PTC) device that prevents
motor burn out.
REMOTE KEYLESS ENTRY SYSTEM
²LOCK: Pressing the LOCK button locks all
doors and sounds horn (chirp) and arm the Vehicle
Theft Security System, if equipped. The chirp verifies
that the RKE receiver has sent a message to the
BCM for door lock operation. If a door has not been
closed before pressing the LOCK button, the vehicle
may not be secured and the VTSS will not arm until
the door is closed.
²UNLOCK: Pressing the UNLOCK button once
will unlock the driver's side doors and activate the
illuminated entry system and disarm Vehicle Theft
Security System, if equipped. Pressing the UNLOCK
button twice within five seconds will unlock all doors
and activate the illuminated entry system.

²LIFTGATE:
Pressing the LIFTGATE BUTTON
opens/closes the liftgate remotely, if equipped.If not
equipped with power liftgate, pressing the liftgate but-
ton will allow a one time 30 second access to liftgate.
²PANIC: Pressing the PANIC button sounds the
horns at half second intervals, flashes the exterior
lamps, and turns ON the interior lamps. The panic
alarm will remain on for three minutes, or until the
PANIC button is actuated again or the ignition
switch is turned to the RUN position.
The Remote Keyless Entry Module is capable of
retaining the transmitter Vehicle Access Code(s)
(VAC) in its memory even after vehicle power has
been interrupted.
NOTE: Additional features available to the customer
are described in the Vehicle Owners Manual.
The RKE system activates the optional memory
seat, mirror system and adjustable pedals, if
equipped. Two primary key fob transmitters can be
programmed to actuate memory seat and mirror set-
ting 1 or 2. Two additional key fob transmitters can be
added, but they will not be able to operate the mem-
ory seat and mirror system (Refer to 8 - ELECTRI-
CAL/POWER SEATS - OPERATION) and (Refer to 8 -
ELECTRICAL/POWER MIRRORS - OPERATION).
DOOR CYLINDER LOCK
SWITCH
DESCRIPTION
The Door Cylinder Lock Switch is used to:
²Unlock/Lock all the doors via the Central Lock-
ing feature.
²Arm/Disarm the Vehicle Theft Security System.
²Trigger the Illuminated Entry feature.
The door cylinder lock switch is mounted to the
rear of the driver and passenger door lock cylinders.
When installed on the rear of the cylinder, there is a
tab on the lock cylinder that aligns with the switch
to prevent it from turning. An anti-rotating device.
The door cylinder lock switch is a one time use
switch. Once it is removed from the rear of the door
lock cylinder, it may not be reinstalled and a new
switch must be used.
OPERATION
When the Door Cylinder Lock Switch is turned
either way using the door key cylinder, the BCM
reads a direct message signal from the switch, via
the Programmable Communication Interface (PCI)
bus.
If turning the key cylinder once, toward the front
of the vehicle (for either driver or passenger doors),
this will:
(1) Mechanically unlock the door lock.
(2) Disarm the Vehicle Theft Security System (if
equipped).
(3) Turn on the Illuminated Entry (if equipped) for
approximately 30 seconds.
If the key cylinder is turned to the unlock position
(toward the front of vehicle) twice within two sec-
onds, all the doors and liftgate will unlock (if
equipped with the central locking feature).
To lock the vehicle using the door cylinder lock
switch, turn the key cylinder toward the rear of the
vehicle (either passenger or driver doors) once. This
will lock the door that you are using the key on. If
equipped with the central locking feature, this will
lock all the other doors and liftgate. Furthermore,
this will arm the vehicle theft security system and
turn off the illuminated entry.
DIAGNOSIS AND TESTING - DOOR CYLINDER
LOCK SWITCH

REMOTE KEYLESS ENTRY
MODULE
DESCRIPTION
The RKE module is capable of retaining up to four
different Vehicle Access Codes.
OPERATION
Whenever the vehicle battery power is interrupted
the RKE Module will retain all vehicle access codes
in its memory. When replacing or adding a key fob
transmitter (maximum 4) a DRB IIItscan tool is
required to program the RKE Module to accept the
new Vehicle Access Code if a customer owned trans-
mitter is not available. Refer to Electrical, Remote
Keyless Entry Module, Standard Procedure - Pro-
gramming RKE Module or the Proper Body Diagnos-
tic Procedures manual.
DIAGNOSIS AND TESTING - REMOTE KEYLESS
ENTRY MODULE
Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, further details
on wire harness routing and retention, as well as
pin-out and location views for the various wire har-
ness connectors, splices and grounds. Refer to the
proper Body Diagnostic Procedures Manual for test-
ing the Remote Keyless Entry system using a DRB
IIItscan tool. Also refer to other interrelated sys-
tems groups within this manual:

STANDARD PROCEDURE - PROGRAMMING
RKE MODULE
(1) Using a functional key fob transmitter, unlock
the vehicle and disarm the Vehicle Theft Security
System.
(2) Insert ignition key into the ignition switch.
(3) Turn the ignition switch to RUN position with-
out starting engine.
(4) Using a functional key fob transmitter, press
and hold the UNLOCK button for a minimum five
seconds (maximum ten seconds).
(5) While still holding UNLOCK button, and
before ten seconds passes, press the PANIC button
and release both at the same time. A single chime
will sound to verify that the RKE module is set to
receive the new Vehicle Access Code(s).
(6) Within 30 seconds of the chime, press and
release the ªLOCKº and ªUNLOCKº buttons on the
transmitter at the same time. Then press and release
any one of the buttons. The BCM will sound anabbreviated chime to acknowledge that the program-
ming of the transmitter has been completed and was
successful.
(7) Repeat step 6 for all transmitters that will be
used with this vehicle (up to 4 total).
(8) Programming mode will last for 30 seconds. To
get out of programming mode sooner, turn the igni-
tion OFF. A single chime will sound to verify that the
RKE module will no longer accept additional Vehicle
Access Code(s).
(9) When Vehicle Access Code(s) programming is
complete, turn the ignition switch to the OFF posi-
tion and verify RKE system operation using each key
fob.
NOTE:
Only the two key fob transmitters that have been
programmed to the memory seat and mirror system
will operate it. If any key fob is replaced, the mem-
ory seat and mirror module will require program-
ming. (Refer to 8 - ELECTRICAL/POWER SEATS -
DIAGNOSIS AND TESTING).
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove instrument panel top cover (Refer to
23 - BODY/INSTRUMENT PANEL/INSTRUMENT
PANEL TOP PAD - REMOVAL).
(3) Remove screws holding RKE module to instru-
ment panel.
(4) Disconnect wire connector from RKE module
(Fig. 4).
(5) Remove the RKE module from vehicle.

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
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 outside mirror, there is a 2±pin con-
nector. 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.
