Traveler Display Functions - Chrysler Concorde 2004 Service Manual

GENERAL INFORMATION
• Driver warning messages
The CMTC/EVIC receives the following messages
from the Powertrain Control Module (PCM):
• Trip Odometer data
• Vehicle Speed
The CMTC/EVIC transmits the following mes-
sages to the BCM:
• Status Request: Beep, Reset, US/M Toggle
• Current Display
STEP BUTTON
The STEP Button can be used in one of the
following three ways:
1. To sequentially select one of seven displays or
blank display in the following order:
•
Average Fuel Economy
• Distance to Empty
• Trip Odometer
•
Time Elapsed
•
Distance to Service Message
• Individual Tire Pressure (When equipped with
TPM.)
•
Off (Blank)
2. To set the magnetic variance zone when VARI-
ANCE = X (X = 1 - 15) is indicated in the VF
Display.
3. To select the displayed programmable feature
setting. (When equipped.)
MENU BUTTON
Use the MENU button to sequentially step the
EVIC through the programmable features.
Use the MENU button to enter the Tire Pressure
Monitoring (TPM) Training Procedure.
RESET BUTTON
The RESET Button has two different functions:
1. To clear the trip functions that may be reset
2. To enter and exit the diagnostic mode
Pressing the RESET button once will clear the
trip function that is currently being displayed (ex-
cept Distance to Service) and the CMTC/EVIC will
send a PCI bus beep request to the BCM. If the
RESET button is pressed again within 3 seconds,
the CMTC/EVIC will reset ALL of the trip functions
and an additional beep request is sent to the BCM.
The trip functions that may be reset are:
• Average Fuel Economy
• Trip Odometer
• Elapsed Time
A reset will only occur if one of the trip functions
that may be reset is currently being displayed.
Pressing the RESET button for more than three (3)
seconds resets the Distance to Service function
while the Distance to Service message is being
displayed. The CMTC/EVIC module will send a
beep request to the BCM.
Simultaneously pressing the RESET button and
the C/T button while turning the ignition from Off
to On will enter the CMTC/EVIC into the self-
diagnostic mode.
COMPASS/TEMPERATURE (C/T) BUTTON
Actuating the Compass/Temperature Button
(C/T) will cause the CMTC/EVIC to display the
compass and temperature information. This func-
tion will operate from another traveler display or
from the programmable feature mode.

3.11.1 TRAVELER DISPLAY FUNCTIONS

Using the STEP button will change the CMTC/
EVIC between modes of operation and display the
appropriate information according to data received
from the PCI Bus.
COMPASS/TEMPERATURE
The CMTC/EVIC simultaneously displays the
compass reading and the outside temperature. Out-
side temperature information is received via the
PCI bus from the PCM.
The CMTC/EVIC module internally senses and
calculates the compass direction.
COMPASS OPERATION
Upon ignition on, if the calibration information
stored in the CMTC/EVIC memory is within the
normal range, the CMTC/EVIC will perform in slow
Auto-Cal mode. In slow Auto-Cal mode, the CMTC/
EVIC continuously compensates for the slowly
changing magnetic field of the vehicle. The compass
module detects changes in the vehicle magnetism
and makes appropriate internal corrections to en-
sure proper displayed direction.
However, if the calibration information stored in
the CMTC/EVIC memory is not within the normal
range at ignition on, the CMTC/EVIC will enter fast
Auto-Cal. CAL is displayed along with the temper-
ature.
Auto activation of the fast Auto-Cal mode will
also occur when the CMTC/EVIC is subjected to
high magnetic field strength levels, which cause all
compass readings to be erroneous for a continuous
period of five (5) minutes. During fast Auto-Cal,
CAL will be displayed along with the temperature.
