GENERAL INFORMATION

3.12.3.2

TRAVELER DISPLAY FUNCTIONS

Using the STEP button will change the EVIC

between modes of operation and display the appro-
priate information according to data received from
the PCI Bus.

COMPASS
The EVIC displays the compass reading. The EVIC
receives the compass information from the over-
head console.

COMPASS OPERATION - ALL
Upon ignition on, if the calibration information
stored in the CMTC memory is within the normal
range, the CMTC will perform in slow Auto-Cal
mode. In slow Auto-Cal mode, the CMTC continu-
ously compensates for the slowly changing mag-
netic field of the vehicle. The compass module
detects changes in the vehicle magnetism and
makes appropriate internal corrections to ensure
proper displayed direction. However, if the calibra-
tion information stored in the CMTC memory is
not within the normal range at ignition on, the
CMTC will enter fast Auto-Cal mode. Auto activa-
tion of the fast Auto-Cal mode occurs when the
CMTC is subjected to high magnetic field strength
levels, which cause all compass readings to be
erroneous for a continuous period of five (5) min-
utes. During fast Auto-Cal,

9COMPASS CALI-

BRATING

9 will display. Fast Auto-Cal can also be

performed manually, by completing one 360° turn
in an area free from large metal or metallic objects.
When complete, the

9COMPASS CALIBRATING9

EVIC message will turn off and the compass will
function normally.

3.12.3.3

SETTING MAGNETIC ZONE
VARIANCE

Variance is the difference between magnetic

North and geographic North. For proper compass
function, the correct variance zone must be set.
Refer to the Zone Variance map for the correct
zone. Follow these steps to check or change the
variance zone:

•

The ignition switch must be in the On position
and the EVIC display must not be blank.

•

If the compass data is not displayed, step
through until the compass information displays.

•

Press and hold the RESET button (approxi-
mately 5 seconds) until VARIANCE = XX is
displayed. The EVIC will display the variance
zone stored in memory and the word VARI-
ANCE.

•

Use the RESET button to select the proper
variance zone number, 1 through 15.

•

After selecting the proper zone number, momen-
tarily press and release the RESET button. The
variance zone is then stored in the memory and
the EVIC returns to normal operation.

3.12.3.4

COMPASS CALIBRATION

The compass module has 2 types of auto-

calibration; slow-cal and fast-cal. Slow-cal ensures
that during normal vehicle operation the compass
performs auto-calibration functions to keep the
compass sensors in their proper operating range.
Whenever the ignition is On and the EVIC receives
PCI Bus data indicating that engine RPM is

GENERAL INFORMATION

greater than zero, auto-calibration is performed
continuously. If the calibration information stored
in the compass module memory is not within the
normal range after a power-up cycle, the compass
will display

9COMPASS CALIBRATING.9 The

EVIC will enter into the fast-cal mode until cali-
bration is complete. To enter the compass into
Manual Calibration mode, perform the following
steps:

•

Drive the vehicle to an area away from any large
metal objects or overhead power lines.

•

Ensure that the proper variance zone is selected.
See Setting Magnetic Zone Variance.

•

The ignition switch must be in the On position
and the EVIC display must not be blank.

•

Press the STEP button until the Compass dis-
plays in the EVIC.

•

Press and hold the RESET button (approxi-
mately 10 seconds) until CAL is displayed, then
release the button.

•

Drive slowly, less than 5 mph (8 km/h) in at least
1 complete 360-degree circle.

•

9COMPASS CALIBRATING9 will remain illumi-
nated to alert the driver that the compass is in
the calibration mode.

•

After calibration is complete,

9COMPASS CALI-

BRATING

9 will turn off.

If the compass appears blank, unable to be

calibrated, or the compass displays false indica-
tions, the vehicle must be demagnetized. Refer to
Compass Demagnetizing Procedure in the Service
Manual.

NOTE: The EVIC will not display information
for any of the screens for which it did not
receive the proper PCI bus data. Refer to the
symptom list in the Overhead Console
section for problems related to CMTC.

3.12.3.5

HOMELINK

T UNIVERSAL

TRANSMITTER

If equipped, the HomeLink

t Universal Trans-

mitter is integrated into the overhead console. For
added security it will operate home security sys-
tems that use coded signals known generically as
Rolling Codes. The overhead console display pro-
vides visual feedback to the driver, indicating
which HomeLink

t transmitter channel button is

being pressed. The HomeLink

t can learn and store

up to three separate transmitter radio frequency
codes to operate garage door openers, security
gates, and security lighting. The HomeLink

t but-

tons are marked with one, two, or three dots. For

complete information, refer to Universal Transmit-
ter in the Service Manual or the Owner’s Manual.

3.12.3.6

TIRE PRESSURE MONITORING
SYSTEM (TPMS)

If equipped with the Tire Pressure Monitoring

System (TPMS), each of the vehicles four wheels
will have a valve stem with a pressure sensor and
radio transmitter built in. Signals from the tire
pressure Sensor/Transmitter are received and in-
terpreted by the Sentry Key Remote Entry Module
(SKREEM). Using the DRBIII

t, go to ANTI-

THEFT for the SKREEM data.

A Sensor/Transmitter in a mounted wheel will

broadcast an RF frequency indicating its pressure
once per minute when the vehicle is in drive mode.
To activate the Sensor/Transmitter operation, the
required SKREEM speed is 13 mph (20 km/h).
Each Sensor/Transmitters broadcast is uniquely
coded so that the SKREEM can monitor the states
of each Sensor/Transmitter on the vehicle. The
SKREEM TPMS does not use a magnet to relearn,
it automatically learns while driving after a
SKREEM or a Sensor/Transmitter has been re-
placed.

3.12.3.6.1

TRAINING THE SKREEM

If a Sensor/Transmitter is replaced, the vehicle

has to be parked for at least 15 minutes for the
system to be ready to learn the new Sensor/
Transmitter ID code. The vehicle then must be
driven for a minimum of five minutes with a
minimum continuous speed above 13 mph (20
km/h). The system will learn the new Sensor/
Transmitter and clear the DTC’s automatically.
The Sensor/Transmitters are programmed at the
assembly plant in this clockwise orientation:

Sensor/Transmitter 1 = Left Front
Sensor/Transmitter 2 = Right Front
Sensor/Transmitter 3 = Right Rear
Sensor/Transmitter 4 = Left Rear

Note:

1. If one or all Sensor/Transmitters cannot be

trained, check for and avoid RF interfer-
ence.

2. If one Sensor/Transmitter still cannot be

trained, replace it and retry.

3. If all Sensor/Transmitters still fail to train,

replace the SKREEM.

3.12.3.6.1.1

PRESSURE THRESHOLDS

The SKREEM will monitor the tire pressure

signals from the Sensor/Transmitters and deter-
mine if any tire has gone below the low-pressure or

above the high-pressure thresholds. Refer to the
tables below:

3.12.3.6.1.2

ACTIVE FAULT AND SYSTEM
ALERTS

An active fault will be triggered when a system

failure has been detected. When this occurs, the
Instrument Cluster will illuminate the TPMS in-
dicator and the SKREEM will store the fault code.
An alert will be triggered when a tire pressure has
gone below or above the set threshold pressure.
When this occurs, the Instrument Cluster will
flash the TPMS indicator. The SKREEM will re-
quest a secondary message to be displayed on the
EVIC (if equipped). Only when a tire pressure has
gone below the set threshold pressure will the
SKREEM request the TPMS indicator to flash and
display the EVIC message (if equipped). When a
high pressure alert occurs, only the EVIC message
will be displayed. This action will be displayed as
long as the alert condition is active.

3.13

INSTRUMENT CLUSTER

The Instrument Cluster receives and sends mes-

sages via the PCI Bus. The indicator lamps will
illuminate briefly for a bulb check when the igni-
tion is turned from off to run. All of the gauges
receive their information via the PCI Bus from the
Powertrain Control Module (PCM) and the Body
Control Module (BCM).

The gauges and the LEDs are not individually

replaceable thereby requiring complete replace-
ment of the Instrument Cluster if a repair is
necessary. In the event that the Instrument Clus-
ter loses communication with other modules on the
PCI Bus, the cluster will display

9no bus9 in the VF

display.

The Trip/Reset button is used to switch the

display from trip to total mileage. Holding the
button when the display is in the trip mode will
reset the trip mileage. This button is also used to
put the cluster into self-diagnostic mode (Early
Build Vehicles Only). The odometer display uses
blue-green vacuum fluorescent digital characters.

The Instrument Cluster has four gauges: Speed-

ometer, tachometer, fuel, and temperature. The
Instrument Cluster uses a vacuum-fluorescent
shift indicator.

The Instrument Cluster contains the Chime tone

generator. The cluster provides a 5-volt pull-up to
the BCM, which uses a hardwire low-side driver to
control the chime. The cluster monitors the PCI
bus and based on information from various mod-
ules, and cluster internal parameters, will request
chimes from the BCM as well as illuminating the
appropriate warning indicators.

The odometer display and door/liftgate-ajar mes-

sage comes on when a door is opened. This feature
assists both the customer and the service techni-
cian by allowing them to view the odometer with-
out turning the ignition on. The cluster has the
following warning indicators: Turn Signals (green),
High Beam (blue), Check Engine (amber), Oil Pres-
sure (red), Seat Belt (red), Charging System (red),
Airbag (red), Low Fuel (amber), Engine Tempera-
ture (Red), Brake/Park Brake (red), ABS (amber),
Traction Control (amber), Front Fog (green), Tire
Pressure Monitoring System (amber - if equipped).
For complete details of the Instrument Cluster,
refer to the CS Service Information.

2. Release the Odometer reset button.

The Instrument Cluster will illuminate all indi-

cators and step the gauges through several calibra-
tion points. Also, the odometer will display any
stored codes that may have set.

INTEGRATED POWER MODULE
(IPM)

The Integrated Power Module (IPM) is an elec-

trical control and interface center located in the
engine compartment. The IPM houses in one mod-
ule what is known in other vehicles as the Power
Distribution Center and the Front Control Module.
The IPM, with its fuses and relays provides power
and signal distribution throughout most of the
vehicle. The IPM receives both hard wire and
digital electronic inputs from the vehicle electrical
system. Based on these inputs and the ignition
switch position, it provides direct power feeds and
relay control to some of the vehicles’ most critical
electrical systems.

The Integrated Power Module provides the fol-

lowing features:
