TIRE PRESSURE MONITORING
DESCRIPTION
The EVIC will monitor the tire pressure signals
from the five tire sensors and determine if any tire
has gone below the low pressure threshold or raised
above the high pressure threshold. Refer to the table
below.
LOW TIRE PRESSURE THRESHOLDS
SYSTEM STATUS
INDICATORTIRE PRESSURE

OFF 214 kPa (31 PSI)

OFF 276 kPa (40 PSI)
The Remote Tire Pressure Monitors (RTPM) are
not internally serviceable. For a Sensor Failure or
Low Battery fault, the RTPM must be replaced.
OPERATION
If equipped with the Tire Pressure Monitoring Sys-
tem, each of the vehicle's five wheels will have a
valve stem with a pressure sensor and radio trans-
mitter built in. Signals from the tire pressure sensors
are received and interpreted by the Electronic Vehi-
cle Information Center (EVIC). A sensor in a
mounted wheel will broadcast its detected pressure
once per minute when the vehicle is moving faster
than 40 km/h (25 mph). The spare tire sensor will
broadcast once every hour. Each sensor's broadcast is
uniquely coded so that the EVIC can determine loca-
tion. The individual tire pressures can be displayed
graphically on the EVIC
DIAGNOSIS AND TESTING - TIRE PRESSURE
MONITORING SYSTEM
All Tire Pressure Monitoring System Faults are
specific to one location. If a9BATTERY LOW9or
9SENSOR FAILURE9fault is detected, the location
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.
For additional system description and diagnosis,
refer to Tire Pressure Monitoring in the Body Diag-
nostic manual.
SENSOR
REMOVAL - TIRE PRESSURE SENSOR/
TRANSMITTER
(1) Remove the tire/wheel from the vehicle.
CAUTION: When removing the stick on balancing
weights from the wheel, do not use an abrasive
cleaner or a cleaner which will damage the protec-
tive finish on the wheel.
(2) Remove the balancing weights from the wheel.
NOTE: The cap used on this valve stem contains an
O-ring seal to prevent contamination and moisture
from entering the valve stem. Retain this valve stem
cap for re-use. Do not substitute a regular valve
stem cap in its place.
(3) Remove the cap from the valve stem.
NOTE: 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 reinstalled
and not substituted for a valve stem core made of a
different material. This is required to prevent corro-
sion in the valve stem caused by the different met-
als.
(4) Using the appropriate tool, remove the core
from the valve stem (Fig. 20).
(5) Let the tire fully deflate.

CAUTION: The pressure transmitter must be
removed from the wheel and dropped into the tire
prior to breaking the bead and dismounting the tire.
Failure to do this will greatly increase the risk of
damaging the pressure transducer when servicing
the tire.
(6) Remove nut mounting valve stem of pressure
sensor/transmitter to the wheel (Fig. 21). Drop sen-
sor/transmitter into tire.
CAUTION: When breaking the top and bottom bead
of the tire off the wheel, care must be used so the
bead breaking mechanism on the tire changer does
not damage the wheel. This includes the surface of
the wheel flange on the inside of the wheel.
(7) Using the tire changer manufacturers proce-
dure, first break down the upper bead of the tire.
Then break down the bottom bead of the tire.
CAUTION: When dismounting the upper tire bead
from the wheel, the proper procedure must be used.
Not using the proper procedure will result in dam-
age to the wheel and tire.(8) Dismount the upper bead of the tire from the
wheel.The upper bead must be fully dis-
mounted from the wheel to remove the tire
pressure transmitter from the inside of the tire.
The bottom bead of the tire does not need to be
removed from the wheel.
(9) Pull upward on the tire (Fig. 22). Reach into
the tire and remove the pressure sensor/transmitter
from inside the tire.
INSTALLATION - TIRE PRESSURE SENSOR/
TRANSMITTER
NOTE: When installing the tire pressure sensor/
transmitter, inspect the sealing O-ring at the bottom
of the valve stem for any sign of damage or deteri-
oration. Replace O-ring if necessary, before install-
ing the pressure transmitter on the wheel. Also, be
sure the surface of the wheel that the O-ring seals
against is clean and not damaged.

SENSOR (Continued)

(1) Install the tire pressure sensor/transmitter on
the wheel (Fig. 23).
(2) Tighten the tire pressure sensor/transmitter
mounting nut to a torque of 11 N´m (97 in. lbs.) (Fig.
24). When tightening the sensor/transmitter nut,
hold the transmitter so it does not rotate. If the sen-
sor/transmitter rotates so the top edge is not level
with the wheel (Fig. 25), damage to the transmitter
will occur when mounting the tire. If the top edge of
the transmitter is not level with the wheel, it can be
rotated into position by lightly tapping it with your
hand.
CAUTION: When mounting the upper bead of the
extended mobility tire, the proper procedure must
be used. Not using the proper procedure will result
in damage to the wheel and tire.
(3) Mount the upper bead of the tire on the wheel.
(4) Install the original or an OEM replacement
valve stem cap on the valve stem.
(5) Using a soap solution, check that no air leak is
present where the valve stem mounts to the wheel.
(6) Balance the tire/wheel assembly using the cor-
rect procedure for using wheel flange mount and
stick-on wheel weights. For balancing information
and wheel weight positioning, (Refer to 22 - TIRES/
WHEELS - STANDARD PROCEDURE).
(7) Install the tire/wheel on the vehicle (Refer to
22 - TIRES/WHEELS - STANDARD PROCEDURE).
(8) Program the identification code for the new tire
pressure sensor/transmitter into the TPM module.(9) Verify that the TPM module has been pro-
grammed with the identification code from the new
tire pressure sensor/transmitter Refer to the appropi-
ate electrical section. If the identification code and
tire pressure thresholds from the new tire pressure
transmitter are present in the receivers memory the
new tire pressure transmitter has been correctly pro-
grammed to the receiver.

(2) Apply silicone lubricant to a cloth and wipe it
on door seals to avoid over-spray that can soil pas-
senger's clothing.
(3) Before applying lubricant, the component
should be wiped clean. After lubrication, any excess
lubricant should be removed.
(4) The hood latch, latch release mechanism, latch
striker, and safety latch should be lubricated period-
ically.
(5) The door lock cylinders should be lubricated
twice each year (preferably autumn and spring).
(a) Spray a small amount of lock cylinder lubri-
cant directly into the lock cylinder.
(b) Apply a small amount to the key and insert
it into the lock cylinder.
(c) Rotate it to the locked position and then back
to the unlocked position several times.(d) Remove the key. Wipe the lubricant from it
with a clean cloth to avoid soiling of clothing.
STANDARD PROCEDURE - DRILLING AND
WELDING
When holes must be drilled or punched in an inner
body panel, verify depth of space to the outer body
panel, electrical wiring, or other components. Dam-
age to vehicle can result.
Do not weld exterior panels unless combustible
material on the interior of vehicle is removed from
the repair area. Fire or hazardous conditions, can
result.
Always have a fire extinguisher ready for use when
welding.
