Removal - Chrysler Concorde 2004 Service Manual

22 - 12 TIRES/WHEELS
SENSOR - TPM (Continued)
CAUTION: Never attempt to train more than one
vehicle at a time. System is capable of reading tire
pressure sensor transmissions from other nearby
vehicles while in train mode.
Each time a wheel rotation or tire pressure sensor
replacement occurs the tire pressure sensors must be
retrained. This is necessary to inform the Electronic
Vehicle Information Center (EVIC) that a sensor
change was made and the new locations of the sen-
sors. Retraining is accomplished through the EVIC
used in conjunction with a Re-learn Magnet, Special
Tool 8821.
NOTE: Use the following procedure to retrain all
five (5) tire pressure sensors. No attempt should be
made to retrain individual sensors.
(1) Open decklid and remove spare tire stowage
cover.
(2) Retrieve Re-learn Magnet, Special Tool 8821.
(3) Press MENU Button on EVIC until RETRAIN
TIRE SENSORS - NO is displayed.
(4) Press STEP button to select YES .
NOTE: There is a 60 second timer for training the
first sensor and a 30 second timer between training
the remaining sensors. If either of these timers
expire, the EVIC will abort the training procedure.
NOTE: If at any time the EVIC display reads TRAIN-
ING ABORTED , move the vehicle ahead at least
one foot and repeat the entire retraining procedure.
(5) Press MENU button to start retraining. Dis-
play will read TRAIN LEFT FRONT TIRE
NOTE: The order for retraining all five sensors is:
• Left Front
• Right Front
• Right Rear
• Left Rear
• Spare
(6) Starting at left front tire, place Re-learn Mag-
net over valve stem (Fig. 17). Within approximately 5
seconds, vehicle horn will chirp indicating training
complete for that particular sensor. Remove the mag-
net.
(7) Repeat step (6) on remaining sensors as indi-
cated by EVIC until all five TPM sensors positions
are trained.
(8) Once EVIC displays TRAINING COMPLETE ,
pressing either STEP, C/T, RESET or MENU button
will exit training routine.

REMOVAL

(1) Remove tire and wheel assembly from vehicle.
(Refer to 22 - TIRES/WHEELS - REMOVAL)
CAUTION: The cap used on this valve stem con-
tains an O-ring seal to prevent contamination and
moisture from entering the valve stem. Retain this
valve stem cap for reuse. Do not substitute a regu-
lar valve stem cap in its place.
CAUTION: The valve stem used on this vehicle is
made of aluminum and the core is nickel plated
brass. The original valve stem core must be rein-
stalled and not substituted with a valve stem core
made of a different material. This is required to pre-
vent corrosion in the valve stem caused by the dif-
ferent metals.
(2) Dismount tire
changer manufacturers instructions while paying
special attention to the following to avoid damaging
the pressure sensor:
(a) When breaking the tire bead loose from the
wheel rim, avoid using the Bead Breaker in the
area of the sensor. That includes both front and
rear beads of the tire.
(b) When preparing to dismount the tire from
the wheel, carefully insert the mounting/dimount-
ing tool at the valve stem ± 10° (Fig. 18), then pro-
ceed to dismount the tire from the wheel. Use this
process on both the upper and lower tire beads.
(3) Using a thin wall socket, remove special nut
retaining sensor to wheel (Fig. 19).
(4) Remove sensor from wheel (Fig. 19).
