OPERATION
The relay is supplied fused B+ voltage, energized
by the PCM/TCM, and is used to supply power to the
solenoid pack when the transmission is in normal
operating mode. When the relay is ªoffº, no power is
supplied to the solenoid pack and the transmission is
in ªlimp-inº mode. After a controller reset (ignition
key turned to the ªrunº position or after cranking
engine), the PCM/TCM energizes the relay. Prior to
this, the PCM/TCM verifies that the contacts are
open by checking for no voltage at the switched bat-
tery terminals. After this is verified, the voltage at
the solenoid pack pressure switches is checked. After
the relay is energized, the PCM/TCM monitors the
terminals to verify that the voltage is greater than 3
volts.
TRANSMISSION RANGE
SENSOR
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted
to the top of the valve body inside the transaxle and
can only be serviced by removing the valve body. The
electrical connector extends through the transaxle
case (Fig. 328).
The Transmission Range Sensor (TRS) has four
switch contacts that monitor shift lever position and
send the information to the PCM/TCM.The TRS also has an integrated temperature sen-
sor (thermistor) that communicates transaxle tem-
perature to the TCM and PCM (Fig. 329).
OPERATION
The Transmission Range Sensor (TRS) (Fig. 328)
communicates shift lever position (SLP) to the PCM/
TCM as a combination of open and closed switches.
Each shift lever position has an assigned combination
of switch states (open/closed) that the PCM/TCM
receives from four sense circuits. The PCM/TCM inter-
prets this information and determines the appropriate
transaxle gear position and shift schedule.

OPERATION
The Brake/Transmission Shift Interlock (BTSI)
Solenoid prevents the transmission shift lever from
being moved out of PARK (P) unless the brake pedal
is applied. The BTSI solenoid is hardwired to and
controlled by the Intelligent Power Module (IPM).
Battery voltage is applied to one side of the solenoid
with the ignition key is in either the OFF, ON/RUN,
or START positions (Fig. 265). The ground side of the
solenoid is controlled by a driver within the IPM. It
relies on voltage supplied from the stop lamp switch
to the stop lamp sense circuit within the IPM to tell
when the brake pedal is depressed. When the brake
pedal is depressed, the ground circuit opens, de-ener-
gizing the solenoid. When the brake pedal is
released, the ground circuit is closed, energizing the
solenoid.
When the ignition key is in either the OFF,
ON/RUN, or START positions, the BTSI solenoid is
energized, and the solenoid plunger hook pulls the
shift lever pawl into position, prohibiting the shift
lever from moving out of PARK (P) (Fig. 266). When
the brake pedal is depressed, the ground circuit
opens, de-energizing the solenoid. This moves the
gearshift lever pawl out of the way (Fig. 267), allow-
ing the shift lever to be moved into any gear position. A conventional mechanical interlock system is also
used. This system manually prohibits shifter move-
ment when the ignition switch is in the LOCK or
ACC positions. Solenoid operation is not required in
these key positions.

TRANSMISSION CONTROL RELAY
DESCRIPTION
The transmission control relay (Fig. 302) is located
in the Intelligent Power Module (IPM), which is
located on the left side of the engine compartment
between the battery and left fender.
OPERATION
The Transmission Control Relay is supplied fused
B+ voltage, energized by the PCM, and is used to
supply power to the solenoid pack when the trans-
mission is in normal operating mode. When the relay
is ªoffº, no power is supplied to the solenoid pack and
the transmission is in ªlimp-inº mode. After a control-
ler reset (ignition key turned to the ªrunº position or
after cranking engine), the PCM energizes the relay.
Prior to this, the PCM verifies that the contacts are
open by checking for no voltage at the switched bat-
tery terminals. After this is verified, the voltage at
the solenoid pack pressure switches is checked. After
the relay is energized, the PCM monitors the termi-
nals to verify that the voltage is greater than 3 volts.

TIRE PRESSURE MONITORING
DESCRIPTION
Some versions of this vehicle are equipped with a
Tire Pressure Monitoring (TPM) system. It monitors
air pressure in the four road tires. Pressure in the
spare tire is not monitored. There is a sensor (transmitter) in each of the vehi-
cle's four road wheels that is built in to the valve
stem. The system alerts the driver when tire pres-
sure falls outside predetermined thresholds (pressure
too low or too high). A message is then displayed on
the Compass Mini Trip Computer (CMTC). For further information, refer to the Owners Man-
ual or the appropriate diagnostic information.
OPERATION
The Tire Pressure Monitoring (TPM) system uses
radio and sensor technology to monitor tire air pres-
sure levels. Sensors, mounted to each road wheel as
part of the valve stem, transmit an RF frequency
indicating their individual pressure to a receiver
located in the Sentry Key Remote Entry Module
(SKREEM). These transmissions occur approximately
once every minute at speeds over 13 mph (20 km/h).
The Tire Pressure Monitoring system remains active
even if no tire pressure related message is displayed.
SENSOR - TPM
DESCRIPTION
On vehicles equipped with Tire Pressure Monitor-
ing, one tire pressure sensor is mounted to each
wheel (Fig. 2). Each sensor has an internal battery
that lasts up to 10 years. The battery is not service-
able. At the time of battery failure, the sensor must
be replaced. The serviceable components of the tire
pressure sensor are: ² Sensor-To-Wheel Grommet
² Valve Stem Cap
² Valve Stem Core
Valve stem caps and cores are specifically designed
for the tire pressure monitoring sensors. Although
similar to standard valve stem caps and cores, they
are different.
CAUTION: Do not use a standard valve stem cap or
core in a tire pressure sensor. Always use the orig-
inal equipment style sensor cap and core.
CAUTION: Do not reuse the Sensor-To Wheel Grom-
met. Always use a new grommet when installing a
pressure sensor and properly torque the sensor
nut.

BODY LUBRICATION
LUBRICATION REQUIREMENTS
Body mechanisms and linkages should be
inspected, cleaned, and lubricated, as required, to
maintain ease of operation and to provide protection
against rust and wear. When performing other under
hood services, the hood latch release mechanism and
safety catch should be inspected, cleaned, and lubri-
cated. During the winter season, external door lock
cylinders should be lubricated to assure proper oper-
ation when exposed to water and ice.
Prior to the application of any lubricant, the parts
concerned should be wiped clean to remove dust and
grit. If necessary, a suitable solvent can be used to
clean the item to be lubricated. After lubricating acomponent, any excess oil or grease should be
removed.LUBRICANT APPLICATION
DOOR LOCK CYLINDERS
(1) Apply a small amount of lubricant directly into
the lock cylinder.
(2) Apply a small amount of lubricant to the key.
(3) Insert key into lock cylinder and cycle the
mechanism from the locked to the unlocked position.
NOTE: Do not add more lubricant.
(4) Cycle the lock cylinder mechanism several
times to allow the lubricant to flow throughout the
cylinder.
