MULTI-FUNCTION SWITCH
DESCRIPTION - TURN SIGNAL SYSTEM
The turn signals are actuated with a lever on
Multi-Function Switch, located on the left side of the
steering wheel. The signals are automatically turned
off by a canceling cam (two lobes molded to the clock
spring mechanism). The cam comes in contact with
the cancel actuator on the turn signal (multi-func-
tion) switch assembly. Either cam lobe, pushing on
the cancel actuator, returns the switch to the OFF
position. The multi-function switch is a resistive
MUX switch that feeds inputs to the BCM.
OPERATION - TURN SIGNAL SYSTEM
Lane change signaling is actuated by applying par-
tial turn signal stalk movement toward the direction
desired until the indicator lamps flashes in the
instrument cluster. When the switch stalk is released
the stalk will spring back into the neutral position
turning OFF the turn signal.
With the ignition switch ON and the turn signal
switch stalk actuated left or right, current flows
through the:
²Multi-function switch
²Body Control Module
²Integrated Power Module (IPM)
²Turn indicator lamp
²Front and rear turn signal bulbs.
A chime will sound after the vehicle has traveled a
distance of approximately 1.0 mile and a speed of 15
mph, with the turn signal ON.

UNIVERSAL TRANSMITTER
DESCRIPTION
A Universal Transmitter transceiver is available on
some vehicles. The universal transmitter transceiver
is integral to the Electronic Vehicle Information Cen-
ter (EVIC) and the Compass Mini-Trip Computer
(CMTC) modules, which are located in the overhead
console. The only visible component of the universal
transmitter are the three transmitter push buttons
centered between the modules push buttons located
just rearward of the display screen in the overhead
console. The three universal transmitter push but-
tons are identified with one, two or three light indi-
cators so that they can be easily identified.
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.
DIAGNOSIS AND TESTING
UNIVERSAL TRANSMITTER
If both the Universal Transmitter and the Elec-
tronic Vehicle Information Center (EVIC) are inoper-
ative, (Refer to 8 - ELECTRICAL/OVERHEAD
CONSOLE/ELECTRONIC VEHICLE INFO CENTER
- DIAGNOSIS AND TESTING). If the Universal
Transmitter is inoperative, but the EVIC is operating
normally, retrain the Transmitter with a known good
transmitter (Refer to 8 - ELECTRICAL/OVERHEAD
CONSOLE/UNIVERSAL TRANSMITTER - STAN-
DARD PROCEDURE - SETTING TRANSMITTER
CODES). If the unit is still inoperative, test the uni-
versal transmitter with the Radio Frequency Detec-
tor special tool as described below (Fig. 4):
(1) Turn the Radio Frequency (RF) Detector ON. A
ªchirpº will sound and the green power LED will
light. If the green LED does not light, replace the
battery.
(2) Hold the RF detector within one inch of the
TRAINED universal transmitter and press any of the
transmitters buttons.
(3) The red signal detection LEDs will light and
the tool will beep if a radio signal is detected. Repeat
this test three times.

SOLE/COMPASS/MINI-TRIP COMPUTER -
REMOVAL.
AMBIENT TEMP SENSOR
DESCRIPTION
Ambient air temperature is monitored by the over-
head console through ambient temperature messages
received from the Powertrain Control Module (PCM)
over the Programmable Communications Interface
(PCI) data bus circuit. The PCM 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.
For additional information on the PCM, (Refer to 8
- ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/POWERTRAIN CONTROL MODULE -
DESCRIPTION).
OPERATION
The ambient temperature sensor is a variable
resistor that operates on a five-volt reference signal
sent by the Powertrain Control Module (PCM). The
resistance in the sensor changes as temperature
changes, changing the temperature sensor signal cir-
cuit voltage to the PCM. Based upon the resistance
in the sensor, the PCM senses a specific voltage on
the temperature sensor signal circuit, which it is pro-
grammed to correspond to a specific temperature.
The PCM then sends the proper ambient tempera-
ture messages to the Electronic Vehicle Information
Center (EVIC)/Compass Mini-Trip Computer (CMTC)
over the Programmable Communication Interface
(PCI) data bus.
The thermometer function is supported by the
ambient temperature sensor, a wiring circuit, the
PCM, the PCI data bus, and the Electronics module.
If any portion of the ambient temperature sensor cir-
cuit fails, the PCM will self-diagnose the circuit.
The ambient temperature sensor circuit can also be
diagnosed manually (Refer to 8 - ELECTRICAL/
OVERHEAD CONSOLE/AMBIENT TEMP SENSOR
- DIAGNOSIS AND TESTING - AMBIENT TEM-
PERATURE SENSOR CIRCUIT). If the temperature
sensor and circuit are confirmed to be OK, but the
temperature display is inoperative or incorrect,
(Refer to 8 - ELECTRICAL/OVERHEAD CONSOLE -
DIAGNOSIS AND TESTING) to determine the cause.
For complete circuit diagrams, refer to the appropri-
ate wiring information.
DIAGNOSIS AND TESTING
AMBIENT TEMPERATURE SENSOR
(1) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Disconnect the ambient temperature sensor wire har-
ness connector.
(2) Measure the resistance of the ambient temper-
ature sensor. At room temperature (approx. 68ÉF),
the sensor resistance should be between 10-13 Kilo-
hms. The sensor resistance should be between these
two values at 68ÉF. If the resistance is out of range
replace the ambient temperature sensor.
AMBIENT TEMPERATURE SENSOR CIRCUIT
(1) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Disconnect the ambient temperature sensor wire har-
ness connector and the Powertrain Control Module
(PCM) wire harness connector.

(2) Connect a jumper wire between the two termi-
nals in the body half of the ambient temperature sen-
sor wire harness connector.
(3) Check for continuity between the sensor return
circuit and the ambient temperature sensor signal
circuit cavities of the PCM wire harness connector.
There should be continuity. If OK, go to Step 4. If not
OK, repair the open sensor return circuit or ambient
temperature sensor signal circuit to the ambient tem-
perature sensor as required.
(4) Remove the jumper wire from the body half of
the ambient temperature sensor wire harness con-
nector. Check for continuity between the sensor
return circuit cavity of the PCM wire harness connec-
tor and a good ground. There should be no continuity.
If OK, go to Step 5. If not OK, repair the shorted
sensor return circuit as required.
(5) Check for continuity between the ambient tem-
perature sensor signal circuit cavity of the PCM wire
harness connector and a good ground. There should
be no continuity. If OK, (Refer to 8 - ELECTRICAL/

ENGAGE ACTUATOR
DESCRIPTION
The 12 volt engage actuator (Fig. 3) provides the
engagement and disengagement of the liftgate gear
motor to the lift gear by way of an over center link,
activated by a lever.
The engage actuator is a serviceable component
and cannot be repaired, if found to be inoperative it
must be replaced.
OPERATION
The engage actuators normal position is disen-
gaged. When a power liftgate open or close command
is generated from any of the command switches, the
power liftgate control module signals the engage
actuator to move its lever to the engaged position.
This engages the gear motor to the lift gear, so when
the motor turns the lift gate moves upward or down-
wards depending on its current position.
During a manual liftgate open or close cycle the
engage actuator is disengaged, allowing unrestricted
liftgate movement.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the left rear D-pillar trim from the
vehicle, (Refer to 23 - BODY/INTERIOR/LEFT
D-PILLAR TRIM PANEL - REMOVAL).
(3) Manually engage the actuator link rod, this
must be done to access one of the engage actuator
retaining screws.
