Town & Country V6-3.3L VIN R (2003)
PRESSURE THRESHOLDS
The EVIC will monitor the tire pressure signals from the tire Sensor/Transmitters and determine if any tire has gone below the low pressure threshold
or exceeded the high pressure threshold. Refer to the table.
CRITICAL AND NON-CRITICAL SYSTEM ALERTS
Critical:
A critical alert will be triggered when a tire pressure has gone below or above a set threshold pressure. The EVIC will request a chime and then
display "X TIRE(S) LOW PRESSURE" or TIRE(S) HIGH PRESSURE". "X" will be the number of tires reporting low or high pressure. The message
will display for the duration of the current ignition cycle or until an EVIC button is pressed. If the display is removed without correcting the condition,
it will reappear without a chime after 300 seconds to warn the driver of the low or high-pressure condition.
Non-Critical:
A non-critical alert with no chime will be triggered when no signal is received from a Sensor / Transmitter or when a Sensor/Transmitter low battery
condition is detected. The EVIC will display "SERVICE TIRE PRESS. SYSTEM".
SYSTEM FAULTS
There are two conditions that 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 condition, it will:
a. Store an active fault code.
b. Request a chime
c. Display "SERVICE TIRE PRESS. SYSTEM".
1. When the EVIC receives a Low Sensor/ Transmitter battery report from a Sensor / Transmitter, it will:
a. Store an active fault code.
b. Request a chime.
c. Display "SERVICE TIRE PRESS. SYSTEM".
Use the DRBIII(R) Inputs/Outputs function to further isolate the specific concern. The DRBIII(R) can be queried to determine the status and battery
condition for each Sensor/Transmitter.
SPARE WHEEL AUTO-DETECT
If the spare tire is mounted on the vehicle, the EVIC will:
1. Detect the change after 15 minutes at or above 32 km/h (20 mph)
2. Query driver: "SPARE TIRE IN USE?" Use the MENU button for YES, and the STEP button for NO. For S, the EVIC will revert to the previous
display and wait five hours. After five hours the EVIC will proceed as in the NO response below.
3. For a NO response, after 15 minutes, the EVIC will display: "ALL 5 TIRES W/VEHICLE? Y" Use the STEP button to select YES or NO, and the
MEN button to confirm.
For a "YES" response, the EVIC will display "SERVICE TIRE PRESS. SYSTEM".
For a "NO" response, the EVIC will revert to previous display and display "ALL 5 TIRES W/VEHICLE ? Y" every time the ignition is cycled to
RUN and the missing tire ID is not received.
DIAGNOSING AND CLEARING SYSTEM FAULTS
All Tire Pressure Monitoring System Faults are specific to one location. If a no-transmit, "LOW BATTERY", "LOW or HIGH PRESSURE" fault is
detected, the location can be determined by the DRBIII(R). The appropriate Sensor/Transmitter can then be replaced or the out-of-specification
pressure condition can be corrected.
-
If a single Sensor/Transmitter cannot be detected by the EVIC, replace that Sensor/Transmitter.
-
If none of the Sensor/Transmitters can be detected, refer to symptoms in the Tire Pressure Monitor section.
-
If a BUCKET COUNTER test fails, and one or more Sensor/Transmitters does not transmit, replace the affected Sensor/Transmitter.
