TURN SIGNAL CANCEL CAM
DESCRIPTION
The turn signal cancel cam is concealed within the
multi-function switch housing below the steering
wheel and the clockspring mechanism. The turn sig-
nal cancel cam consists of a disc unit with two inte-
gral lobes. The upper lobe of the cam has an
alignment hole that is used to align it with another
hole in the back of the multi-function switch mount-
ing housing. The upper surface of the turn signal
cancel cam features three holes, two round and one
oblong. These holes engage and key the cancel cam to
three matching pins in the hub of the clockspring
mechanism. The hub of the clockspring and the turn
signal cancel cam rotate with the steering wheel. The
centered clockspring housing is then secured to the
multi-function switch mounting housing over the top
of the turn signal cancel cam.
The turn signal cancel cam is serviced as a assem-
bly with the multi-function switch housing. The turn
signal cancel cam cannot be repaired and, if faulty or
damaged, the multi-function switch mounting hous-
ing unit must be replaced. (Refer to 8 - ELECTRI-
CAL/LAMPS/LIGHTING - EXTERIOR/LEFT MULTI-
FUNCTION SWITCH - REMOVAL - MULTI-
FUNCTION SWITCH MOUNTING HOUSING).
OPERATION
The turn signal cancel cam has two lobes. When
the turn signals are activated by moving the left
multi-function switch control stalk to a detent posi-
tion, a turn signal cancel actuator is extended from
the inside surface of the multi-function switch hous-
ing toward the center of the steering column and the
turn signal cancel cam. When the steering wheel is
rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn sig-
nal cancel actuator. The cancel actuator latches
against the cancel cam rotation in the direction oppo-
site that which is signaled.

STANDARD PROCEDURE - COMPASS
DEMAGNETIZING
A degaussing tool (Special Tool 6029) is used to
demagnetize, or degauss, the overhead console for-
ward mounting screw and the roof panel above the
overhead console. Equivalent units must be rated as
continuous duty for 110/115 volts and 60 Hz. They
must also have a field strength of over 350 gauss at 7
millimeters (0.25 inch) beyond the tip of the probe.
To demagnetize the roof panel and the overhead
console forward mounting screw, proceed as follows:
(1) Be certain that the ignition switch is in the Off
position, before you begin the demagnetizing proce-
dure.
(2) Connect the degaussing tool to an electrical
outlet, while keeping the tool at least 61 centimeters
(2 feet) away from the compass unit.
(3) Slowly approach the head of the overhead con-
sole forward mounting screw with the degaussing
tool connected.
(4) Contact the head of the screw with the plastic
coated tip of the degaussing tool for about two sec-
onds.(5) With the degaussing tool still energized, slowly
back it away from the screw. When the tip of the tool
is at least 61 centimeters (2 feet) from the screw
head, disconnect the tool.
(6) Place a piece of paper approximately 22 by 28
centimeters (8.5 by 11 inches), oriented on the vehicle
lengthwise from front to rear, on the center line of
the roof at the windshield header (Fig. 3). The pur-
pose of the paper is to protect the roof panel from
scratches, and to define the area to be demagnetized.
(7) Connect the degaussing tool to an electrical
outlet, while keeping the tool at least 61 centimeters
(2 feet) away from the compass unit.
(8) Slowly approach the center line of the roof
panel at the windshield header, with the degaussing
tool connected.
(9) Contact the roof panel with the plastic coated
tip of the degaussing tool. Be sure that the template
is in place to avoid scratching the roof panel. Using a
slow, back-and-forth sweeping motion, and allowing
13 millimeters (0.50 inch) between passes, move the
tool at least 11 centimeters (4 inches) to each side of
the roof center line, and 28 centimeters (11 inches)
back from the windshield header.
(10) With the degaussing tool still energized,
slowly back it away from the roof panel. When the

turn signal has been left on. The EVIC messages and
displays are coordinated with warning indicators in
the instrument cluster to avoid duplication.
The EVIC module contains a central processing
unit and interfaces with other electronic modules in
the vehicle over the Programmable Communications
Interface (PCI) data bus network. The PCI data bus
network allows the sharing of sensor information.
This helps to reduce wire harness complexity, reduce
internal controller hardware, and reduce component
sensor current loads. At the same time, this system
provides increased reliability, enhanced diagnostics,
and allows the addition of many new feature capabil-
ities.
The EVIC module includes the following display
options:
²Compass and Temperature- provides the out-
side temperature and one of eight compass readings
to indicate the direction the vehicle is facing.
²Average fuel economy- shows the average
fuel economy since the last trip computer reset.
²Distance to empty- shows the estimated dis-
tance that can be travelled with the fuel remaining
in the fuel tank. This estimated distance is computed
using the average miles-per-gallon from the last 30
gallons of fuel used.
²Instant fuel economy- shows the present fuel
economy based upon the current vehicle distance and
fuel used information.
²Trip distance- shows the distance travelled
since the last trip computer reset.
²Elapsed time- shows the accumulated igni-
tion-on time since the last trip computer reset.
²Distance to service- shows the distance
remaining until the next scheduled service interval.
²Tire Pressure- shows the tire pressure in each
tire.
²Blank screen- the EVIC compass/temperature/
trip computer VFD is turned off.
The EVIC is capable of displaying the following
alert messages, which are accompanied by an audible
announcement consisting of a series of beeps:
²TURN SIGNALS ON (with vehicle graphic)-
Indicates that a turn signal has remained on for
about 1.6 kilometers (one mile).
²PERFORM SERVICE- Indicates that a cus-
tomer programmable service interval distance has
been reached.
²DOOR OPEN (one or more, with vehicle
graphic)- Indicates that a door is open or not fully
closed.
²LIFTGATE OPEN (with vehicle graphic)-
Indicates that the liftgate is open or not fully closed.
²LIFTGLASS OPEN (with vehicle graphic)-
Indicates that the liftglass is open or not fully closed.²COOLANT LEVEL LOW (with vehicle
graphic)- Indicates that the coolant level in the
engine coolant reservoir is low.
²XX LOW PRESSURE (with vehicle graphic)
- Indicates that the air pressure in the selected tire
is low.
²WASHER FLUID LOW (with vehicle
graphic)- Indicates that the fluid level in the
washer fluid reservoir is low.
The EVIC ªMenuº push button provides the vehicle
operator with a user interface, which allows the
selection of several optional customer programmable
electronic features to suit individual preferences.
Refer toELECTRONIC VEHICLE INFORMA-
TION CENTER PROGRAMMINGin the Service
Procedures section of this group for more information
on the customer programmable feature options.
If the vehicle is equipped with the optional mem-
ory system, the EVIC will display the following mem-
ory system messages:
²MEMORY #X POSITION SET (X = Driver 1
or Driver 2)- This message appears in the EVIC
display each time the memory system is successfully
programmed. It is accompanied by an audible
announcement chime tone.
²MEMORY SYSTEM DISABLED- The memory
system is automatically disabled while the driver
side seat belt is fastened and/or while the automatic
transmission gear selector is in any position except
Park or Neutral. This message appears in the EVIC
display as a reminder when a memory switch push
button is depressed while the memory system is dis-
abled. If the REMOTE LINKED TO MEMORY cus-
tomer programmable feature has been selected, this
message will also appear when the Unlock button of
the Remote Keyless Entry (RKE) transmitter is
depressed while the memory system is disabled.
If the vehicle is equipped with the optional Univer-
sal Transmitter transceiver, the EVIC will also dis-
play messages and an icon indicating when the
Universal Transmitter is being trained, which of the
three transmitter buttons is transmitting, and when
the transceiver is cleared.
If the vehicle is equipped with the optionalTire
Pressure Monitoring System, the EVIC will also
display messages and an icon indicating when the
tire air pressure falls below a given set-point, and
which of the five tires is transmitting the low pres-
sure warning, and when the condition is cleared.
Refer to the Tires/Wheels section of this manual for
complete Tire Pressure Monitoring System descrip-
tion. Refer to this section of the service manual for
EVIC modules function description for the Tire Pres-
sure Monitoring.
Data input for all EVIC functions, including VFD

OPERATION
The EVIC has access to both non-switched and
ignition switched sources of battery current so that
some of its features remain operational at any time,
while others may only operate with the ignition
switch in the On position. When the ignition switch
is turned to the On position, the EVIC module VFD
will return to the last function being displayed before
the ignition was turned to the Off position.
The compass/temperature display is the normal
EVIC display. With the ignition switch in the On
position, momentarily depressing and releasing the
C/T (compass/temperature) push button switch will
cause the EVIC to return to the compass/tempera-
ture/trip computer display mode from any other
mode. While in the compass/temperature/trip com-
puter display mode, momentarily depressing and
releasing the Step push button will step through the
available trip computer display options.
The EVIC trip computer features several functions
that can be reset. The functions that can be reset
are: average fuel economy, trip odometer and elapsed
time. With the ignition switch in the On position and
with one of the functions of the trip computer that
can be reset currently displayed, depressing the
Reset push button twice within three seconds will
perform a global reset, and all of the trip computer
information that can be reset will be reset to zero.
With the ignition switch in the On position and the
function that is to be reset currently displayed,
momentarily depressing and releasing the Reset
push button once will perform a local reset, and only
the value of the displayed function will be reset to
zero. A global or local reset will only occur if the
function currently displayed is a function that can be
reset. The distance to service function can also be
reset using the local reset method, but it will reset
back to the Service Interval distance that is set in
the EVIC programmable features mode. Refer to
ELECTRONIC VEHICLE INFORMATION CEN-
TER PROGRAMMINGin the Service Procedures
section of this group for more information on setting
the Service Interval.

DESCRIPTION
DESCRIPTION - POWER LOCK SYSTEM
A power operated door and liftgate lock system is
standard factory-installed equipment on this model.
The power lock system allows all of the doors and the
liftgate to be locked or unlocked electrically by oper-
ating a switch on either front door trim panel. The
power lock system receives non-switched battery feedthrough a fuse in the Power Distribution Center
(PDC), so that the power locks remain operational,
regardless of the ignition switch position.
The power lock system for this vehicle also has a
door lock inhibit feature, which prevents the power
lock system from being energized with a power door
lock switch if a front door is open with the key in the
ignition. However, the locks can still be operated
manually, with a key, energized with the RKE trans-
mitter or by sliding the door lock lever to the appro-
priate position.
