System Faults - Chrysler Concorde 2004 Service Manual

GENERAL INFORMATION
pressure threshold is exceeded while the ignition is
OFF, the alert will be delayed 8-10 seconds after
ignition ON.
NOTE: The spare tire is only monitored when
equipped with the 5-Tire TPM System.

3.12.4 SYSTEM FAULTS

NOTE: The Remote Tire Pressure Monitors
(RTPM) are not internally serviceable. For a
Sensor Failure or Low Battery fault, the
RTPM must be replaced.
There are four conditions which will cause a Tire
Pressure Monitoring System fault to be set. All fault
codes are associated with a specific wheel location.
1. If the EVIC detects a non-transmitting Sensor/
Transmitter in a road wheel for ten consecutive
minutes with vehicle speed above 25 MPH (40
kph), it will:
a. Store an active fault code.
b. Request a chime.
c. Display ''TIRE SENSOR BAD / MISSING''.
d. Display a dashed line at the wheel location on
the graphic display if the display is activated.
When the EVIC detects:
2. A low pressure sensor battery status,
3. All five sensors transmitting at a shorter than
expected interval or,
4. No valid pressure sensor ID from the spare tire
for 20 consecutive ignition cycles spaced at least
one hour apart, it will:
a. Store an active fault code.
b. Request a chime.
c. Display ''TIRE SENSOR BAD / MISSING''.
Use the DRBIII Input/Output function to fur-
ther isolate the specific concern.
The DRBIII can be queried to determine the
Sensor/Transmitter status:
• ''Invalid Pressure'' - The Sensor/Transmitter is
reporting a negative pressure or a pressure above
434 kPa (63 psi).
• ''Low Batt'' - The Sensor/Transmitter has re-
ported a low battery status for seven consecutive
ignition cycles.
• ''Trained'' - The Sensor/Transmitter ID code is
recognized by the EVIC.
• ''Active'' - The vehicle is moving at 40 km/h (25
mph) and/or the Sensor/Transmitter is ''awake''
and transmitting as expected by the EVIC.
3.12.5 SPARE WHEEL AUTO-LOCATE
(5-TIRE TPM SYSTEM ONLY)
If the spare tire is mounted on the vehicle, the
EVIC will detect the move and determine from the
sensor transmit intervals, which wheels are
mounted and which one is now the spare. The spare
tire sensor/transmitter transmits once per hour.
The sensor/transmitters in the mounted wheels
transmit once per minute when the vehicle is mov-
ing at 40 km/h (25 mph).
3.12.6 REMOVE MAGNET FROM SPARE
(5-TIRE TPM SYSTEM ONLY)
A magnet is used to initiate a sensor ID transmis-
sion. In the EVIC training procedure, the spare
wheel is the last in the sequence. If the magnet is
left on the wheel, the sensor/transmitter will con-
tinue its ID transmission. If the EVIC detects 20
transmissions from the spare wheel in 60 seconds
and the vehicle speed is above 40 km/h (25 mph), it
will:
• request a chime.
•
display ''REMOVE MAGNET FROM SPARE'' for
60 seconds per ignition-ON cycle. 1.6 Tire Pres-
sure Unavailable
The EVIC can detect high radio noise interfer-
ence. When the noise level is too high to distinguish
a transmission from a sensor/transmitter, it will:
• display ''TIRE PRESSURE UNAVAILABLE'' for 5
seconds.
•
request a chime
•
switch back to previous screen.
3.12.7 TIRE PRESSURE NOW AVAILABLE
If the ''TIRE PRESSURE UNAVAILABLE'' mes-
sage was displayed because of radio noise interfer-
ence, the EVIC will:
•
display ''TIRE PRESSURE NOW AVAILABLE''
for 5 seconds.
• request a chime when the noise level no longer
interferes with sensor/transmitter transmis-
sions.
3.12.8 DIAGNOSING AND CLEARING
SYSTEM FAULTS
All Tire Pressure Monitoring System Faults are
specific to one location. If a ''LOW BATTERY'' fault
is detected, the ''TIRE SENSOR BAD / MISSING''
message will be displayed. The appropriate sensor/
transmitter can then be replaced.
If a single sensor/transmitter cannot be detected
by the EVIC, replace that sensor transmitter. If
none of the sensors/transmitters can be detected,
refer to symptoms in the EVIC section.
