SELF-DIAGNOSTIC TEST
A self-diagnostic test is used to determine that the
electronics module is operating properly, and that all
the PCI data bus messages are being received for ini-
tial operation. Initiate the self-diagnostic test as fol-
lows:
(1) With the ignition switch in the Off position, on
Electronic Vehicle Information Center (EVIC) and
Compass Mini-Trip Computer (CMTC) equipped vehi-
cles simultaneously depress and hold theSTEPand
theRESETbuttons. On Compass Temperature Mod-
ule (CT) equipped vehicles depress theC/Tand the
US/Mpush buttons.
(2) Turn the ignition switch to the On position.
(3) Following completion of these tests, the elec-
tronics module will display one of the following mes-
sages:
a.Pass Self Test (EVIC only), PASS (CT,
CMTC)- The electronics module is working properly.
b.Failed Self Test (EVIC only), FAIL (CT,
CMTC)- The electronics module has an internal fail-
ure. The electronics module is faulty and must be
replaced.
NOTE: If the compass functions, but accuracy is
suspect, it may be necessary to perform a variation
adjustment. This procedure allows the compass
unit to accommodate variations in the earth's mag-
netic field strength, based on geographic location.
(Refer to 8 - ELECTRICAL/OVERHEAD CONSOLE -
STANDARD PROCEDURE - COMPASS VARIATION
ADJUSTMENT).
NOTE: If the compass reading display is blank and
only ªCALº appears in the display, demagnetizing
may be necessary to remove excessive residual
magnetic fields from the vehicle. (Refer to 8 - ELEC-
TRICAL/OVERHEAD CONSOLE - STANDARD PRO-
CEDURE - COMPASS DEMAGNETIZING).
STANDARD PROCEDURE
COMPASS CALIBRATION
CAUTION: Do not place any external magnets, such
as magnetic roof mount antennas, in the vicinity of
the compass. Do not use magnetic tools when ser-
vicing the overhead console.The electronic compass unit features a self-cali-
brating design, which simplifies the calibration pro-
cedure. This feature automatically updates the
compass calibration while the vehicle is being driven.
This allows the compass unit to compensate for small
changes in the residual magnetism the vehicle may
acquire during normal use. If the compass readings
appear to be erratic or out of calibration, perform the
following calibration procedure. Also, new service
replacement Electronic Modules (EVIC, CMTC, CT)
must have their compass calibrated using this proce-
dure. Do not attempt to calibrate the compass near
large metal objects such as other vehicles, large
buildings, or bridges; or, near overhead or under-
ground power lines.
NOTE: Whenever the compass is calibrated manu-
ally, the variance number must also be reset. (Refer
to 8 - ELECTRICAL/OVERHEAD CONSOLE - STAN-
DARD PROCEDURE - COMPASS VARIATION
ADJUSTMENT).
Calibrate the compass manually as follows:
(1) Turn the ignition switch to the On position. If
the compass/thermometer data is not currently being
displayed, momentarily depress and release the C/T
push button to reach the compass/thermometer dis-
play.
(2) On Electronic Vehicle Information Center
(EVIC) and Compass Mini-Trip Computer (CMTC)
equipped vehicles depress the Reset push button and
hold the button until ªCALº appears in the display.
This takes about ten seconds, and appears about five
seconds after ªVAR = XXº is displayed. On Compass
Temperature Module (CT) equipped vehicles depress
the C/T push button and US/M push button down
until ªCALº appears in the display. This takes about
ten seconds, and appears about five seconds after
ªVAR = XXº is displayed.
(3) Release the push button(s).
(4) Drive the vehicle on a level surface, away from
large metal objects and power lines, through three or
more complete circles at between five and eight kilo-
meters-per-hour (three and five miles-per-hour) for a
minimum of 48 seconds. The ªCALº message will dis-
appear from the display to indicate that the compass
is now calibrated.
NOTE: If the ªCALº message remains in the display,
either there is excessive magnetism near the com-
pass, or the unit is faulty. Repeat the calibration
procedure one more time.

ELECTRONIC VEHICLE INFO
CENTER
DESCRIPTION
The Electronic Vehicle Information Center (EVIC)
is located in the overhead console. The EVIC features
a large Vacuum Fluorescent Display (VFD) screen for
displaying information, and back-lit push button
switches labeled C/T (compass/thermometer), RESET,
STEP, and MENU. The EVIC module contains a cen-
tral processing unit and interfaces with other elec-
tronic modules in the vehicle over the Programmable
Communications Interface (PCI) data bus circuit.
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 to 8 - ELECTRICAL/OVERHEAD CONSOLE/
ELECTRONIC VEHICLE INFO CENTER - STAN-
DARD PROCEDURE - ELECTRONIC VEHICLE
INFORMATION CENTER PROGRAMMING).
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 transceiver is being trained,
which of the three transmitter buttons is transmit-
ting, and when the transceiver is cleared.Data input for all EVIC functions, including VFD
dimming level, is received through the PCI data bus
circuit. The EVIC module uses its internal program-
ming and all of its data inputs to calculate and dis-
play the requested data. If the data displayed is
incorrect, perform the SELF - DIAGNOSTIC TEST
(Refer to 8 - ELECTRICAL/OVERHEAD CONSOLE -
DIAGNOSIS AND TESTING). If these tests prove
inconclusive, the use of a DRBIIItscan tool and the
proper diagnostic procedures information are recom-
mended for further testing of the EVIC module and
the PCI data bus circuit.
The EVIC module cannot be repaired, and is avail-
able for service only as a unit. This unit includes the
plastic module and display lens. If any of these com-
ponents is faulty or damaged, the complete EVIC
module must be replaced.
OPERATION
The Electronic Vehicle Information Center (EVIC)
uses 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 oper-
ate with the ignition switch in the On position. When
the ignition switch is turned to the On position, the
EVIC module Vacuum Fluorescent Display (VFD)
will return to the last function being displayed before
the ignition was turned to the Off position.
The compass/thermometer display is the normal
EVIC display. With the ignition switch in the On
position, momentarily depressing and releasing the
C/T (compass/thermometer) push button switch will
cause the EVIC to return to the compass/thermome-
ter/trip computer display mode from any other mode.
While in the compass/thermometer/trip computer dis-
play 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:
²Average fuel economy
²Trip odometer
²Elapsed 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 four seconds will per-
form 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 holding the Reset push
button for one second 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 8 -
ELECTRICAL/OVERHEAD CONSOLE/ELEC-
TRONIC VEHICLE INFO CENTER - STANDARD
PROCEDURE).
DIAGNOSIS AND TESTING
ELECTRONIC VEHICLE INFORMATION CENTER
Electronic Vehicle Information Center (EVIC) data
is obtained from the Body Control Module (BCM) on
the Programmable Communications Interface (PCI)
Data Bus circuit. The EVIC will display dashes (- -)
for any of the screens it did not receive the bus mes-
sages. The label corresponding to the missing infor-
mation will be lit. If no EVIC data is displayed,
check the PCI Data Bus circuit communications and
the BCM. If the dimming level is improper check the
PCI Data Bus circuit.
The use of a DRBIIItscan tool and the proper
diagnostic procedures information are recommended
for further testing of the EVIC module and the PCI
data bus circuit. Perform the SELF-DIAGNOSTIC
TEST before replacing the EVIC module (Refer to 8 -
ELECTRICAL/OVERHEAD CONSOLE - DIAGNO-
SIS AND TESTING).
