COMPASS/MINI-TRIP
COMPUTER
DESCRIPTION
The Compass Mini-Trip Computer (CMTC) and
Compass Temperature (CT) computer are modules
located in the overhead console. Vehicles are
equipped with either the CMTC or the CT computers
not both. The CMTC is different in the fact that it is
equipped with the mini-trip feature. The CMTC, CT
consists of a electronic control module with a vacuum
fluorescent display (VFD) and function switches. The
CMTC, CT consists of a electronic module that dis-
plays compass, trip computer (CMTC only), and tem-
perature features. Actuating the STEP push button
(CMTC only) will cause the CMTC to change mode of
operation when ignition is ON. Actuating the STEP
push button (CMTC only) will cause the CMTC to
change mode of operation when ignition is ON.

UNIVERSAL TRANSMITTER
DESCRIPTION
On some RS models a Homelinkttransceiver is
standard factory-installed equipment. The Homelinkt
transceiver is integral to the Electronic Vehicle Infor-
mation Center (EVIC) and the Compass Mini-Trip
Computer (CMTC), which is located in the overhead
console. The only visible component of the Homelinkt
are the three transmitter push buttons centered
between the modules push buttons located just rear-
ward of the display screen in the overhead console.
The three Homelinkttransmitter push buttons are
identified with one, two or three light indicators so
that they be easily identified by sight or by feel.
Each of the three Homelinkttransmitter push but-
tons controls an independent radio transmitter chan-
nel. Each of these three channels can be trained to
transmit a different radio frequency signal for the
remote operation of garage door openers, motorized
gate openers, home or office lighting, security sys-
tems or just about any other device that can be
equipped with a radio receiver in the 286 to 399
MegaHertz (MHz) frequency range for remote opera-
tion. The Homelinktis capable of operating systems
using either rolling code or non-rolling code technol-
ogy.
The electronics module displays messages and a
small house-shaped icon with one, two or three dots
corresponding to the three transmitter buttons to
indicate the status of the Homelinkt. The EVIC mes-
sages are:
²Cleared Channels- Indicates that all of the
transmitter codes stored in the Homelinkthave been
successfully cleared.
²Training- Indicates that the Homelinktis in
its transmitter learning mode.
²Trained- Indicates that the Homelinkthas
successfully acquired a new transmitter code.
²Transmit- Indicates that a trained Homelinkt
transmitter button has been depressed and that the
Homelinktis transmitting.
The Homelinktcannot be repaired, and is avail-
able for service only as a unit with the EVIC or
CMTC modules. If any of these components is faulty
or damaged, the complete EVIC or CMTC module
must be replaced.
OPERATION
The Homelinktoperates on a non-switched source
of battery current so the unit will remain functional,
regardless of the ignition switch position. For more
information on the features, programming procedures
and operation of the Homelinkt, see the owner's
manual in the vehicle glove box.

POWER LIFTGATE SYSTEM
DESCRIPTION
Some vehicles are equipped with an automatic
opening and closing power liftgate system (Fig. 1).
This power liftgate system is a complex system con-
sisting of many components. Some of these compo-
nents are the liftgate gear motor assembly, latch
assembly, lift gear and rod, liftgate control module,
chime/thermistor, full open switch, engage actuator,
pinch sensor, liftgate handle switch, overhead console
switch, key fob switches (Fig. 2), pawl switch and
ratchet switch.
The power liftgate system has its own door control
module, located on the vehicles left body D-pillar
behind the trim panel. (Refer to 8 - ELECTRICAL/
ELECTRONIC CONTROL MODULES/DOOR CON-
TROL MODULE - DESCRIPTION) The power
liftgate gear motor assembly is located just above the
control module. The latch assembly is located in the
bottom center of the power liftgate, below the exte-
rior liftgate handle switch. The power liftgate full
open switch, engage actuator, lift gear and rod are
part of the liftgate gear motor assembly. The pawland ratchet switches are part of the latch assembly.
The pinch sensor or sensors are located along the
right and left sides of the power liftgate, just above
the body line. The liftgate handle switch is an power
release switch and is located in the rear light bar
assembly, just above the license plate. The overhead
console switch is an power open and close command
switch located in the vehicles overhead console.
Safety is of the utmost concern with the power lift-
gate system. Software technology has enabled the
power liftgate control module to detect resistance to
liftgate travel, which allows the power liftgate to stop
and reverse direction anytime an obstruction is felt
or any of the command switches are operated (only in
closing direction). Battery voltage is supplied to the
power liftgate system through a 40 amp fuse, located
in the Intelligent Power Module (IPM) assembly (Fig.
3). In the unlikely event that the power liftgate sys-
tem develops a fault the power liftgate can still be
operated manually with a key, just like a standard
manual liftgate.

POWER LIFTGATE SYSTEM INHIBITORS
²The Power Liftgate may not operate in extreme
temperatures. These extreme temperatures will be
approximately -12É F (-24.4É C) on the low side and
143É F (61.6É C) for the high side. A chime/thermister
assembly in the rear light bar assembly monitors the
outside temperature.
²The vehicles transmission must be in park or
neutral for the power liftgate to start a cycle.
²If multiple obstacles are detected during the
same power open or close cycle the liftgate goes into
manual operation.
²If severe Diagnostic Trouble Codes (DTC) are
stored in the power liftgate control module.
POWER LIFTGATE SYSTEM CAUTIONS AND
WARNINGS
WARNING: ALWAYS DISCONNECT THE NEGATIVE
BATTERY CABLE BEFORE ATTEMPTING ANY
POWER LIFTGATE SYSTEM SERVICE.
WARNING: THERE IS A SMALL AREA ON BOTH
SIDES OF THE LOWER POWER LIFTGATE WHICH
ARE NOT PROTECTED BY PINCH SENSORS.
EXTREME CARE MUST BE TAKEN TO PREVENT
OBJECTS FROM ENTERING THIS AREA ONCE THE
LIFTGATE REACHES THE SECONDARY LATCH
CONTACT (APPROXIMATELY 1/2 INCH BEFORE
FULLY CLOSED).
WARNING: NEVER ATTEMPT TO ENTER OR EXIT
THE VEHICLE WITH THE LIFTGATE IN MOTION.
YOU COULD DAMAGE THE POWER LIFTGATE SYS-
TEM AND/OR COMPONENTS AND/OR CAUSE PER-
SONAL INJURY.
WARNING: NEVER STICK OBJECTS IN THE POWER
LIFTGATE WHEN CINCHING CLOSED. YOU COULDDAMAGE THE VEHICLE, POWER LIFTGATE SYS-
TEM COMPONENTS AND/OR CAUSE PERSONAL
INJURY.
DIAGNOSIS AND TESTING - POWER LIFTGATE
SYSTEM
The power opening and closing power liftgate sys-
tem is a complex system containing many compo-
nents and modules. In order to obtain conclusive
testing the Programmable Communications Interface
(J1850) data bus network and all of the electronic
modules that provide inputs to, or receive outputs
from the power liftgate system must be checked.
The power liftgate system was designed to be diag-
nosed with an appropriate diagnostic scan tool, such
as the DRB IIIt. The most reliable, efficient, and
accurate means to diagnose the power liftgate system
requires the use of a DRB IIItscan tool and the
proper Body Diagnostic Procedures manual. The
DRB IIItcan be used to observe various switch sta-
tuses throughout the power liftgate system to help
the technician diagnose a defective switch or compo-
nent. The DRB IIItcan also be used to actuate var-
ious components throughout the power liftgate
system to help the technician diagnose a defective
component.
Before any testing of the power liftgate system is
attempted, the battery should be fully charged, all
built-in power liftgate system inhibitors read and
understood (Refer to power liftgate system operation)
and all wire harness and ground connections
inspected around the affected areas on the vehicle.
Following are quick reference diagnostic tables to
help when diagnosing and testing the power liftgate
system.

EXTERIOR HANDLE SWITCH
DESCRIPTION
Vehicles equipped with a power liftgate or power
locks utilize a exterior handle switch. The exterior
handle switch is a electronic release switch mounted
to the rear license plate lamp housing assembly,
located just above the license plate. This switch con-
trols the power liftgate release function and is also
capable of reversing the power liftgate when it is in
motion. A full power open cycle cannot be performed
using this switch, only one of the power open com-
mand switches (key fob and overhead console
mounted) can be used to perform a full power open
cycle.
The exterior handle switch is a serviceable compo-
nent. Consult your MoparŸ parts catalog for a spe-
cific part number.
OPERATION
When the exterior handle switch is depressed, with
the liftgate in the closed position. A message is sent
to the Body Control Module (BCM). The Body Con-
trol Module then sends a signal to the power liftgate
control module via the J1850 PCI data bus circuit.
The power liftgate control module then sends a sig-
nal to the power latch mounted actuator, which
moves the liftgate from the primary closed and
latched position to the open and movable position. If
the liftgate is not pulled open once the latch releases
within a few seconds, the latch will cinch closed
again.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Open the liftgate and remove the liftgate trim
panel. Refer to the Body section of the service man-
ual for the procedure.
(3) Remove the rear lamp bar assembly from the

CHIME/THERMISTOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
chime/thermistor assembly. The chime/thermistor
assembly is a small capacitor shaped electrical com-
ponent mounted to the rear license plate lamp hous-
ing assembly (Fig. 15), located just above the license
plate. The chime portion of the assembly controls the
audible chime sound heard at the rear of the vehicle
when the power liftgate is in motion. The thermistor
portion of the assembly is a temperature sensor, used
by the power liftgate module.
The chime/thermistor assembly is a serviceable
component. Consult your MoparŸ parts catalog for a
specific part number.
OPERATION
The chime/thermistor assembly performs two dif-
ferent functions for the power liftgate system. First,
the chime portion provides an audible chime sound
which is controlled by the power liftgate module. The
chime/thermistor assembly is hardwired to the power
liftgate module. Second the thermistor provides a
outside temperature reading by way of a resistance
reading (V- ohms) supplied to the power liftgate
module. As temperature increases the resistance
reading (V- ohms) increases, as temperature
decreases the resistance reading (V- ohms)
decreases.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the rear light bar assembly from the
vehicle. Refer to Body for the procedure.
(3) Using your hands, grasp the light bar at its
sides next to thermistor/chime assembly and gently
pull the two sides of the light bar apart until the
thermistor/chime assembly can be removed.
