Following completion of these tests, the electron-
ics module will display one of the following messages:
a.Pass Self Test (EVIC only), PASS (CT,
CMTC)- The electronics module is working properly.
b.Failed Self Test (EVIC only), FAIL (CT,
CMTC)- The electronics module has an internal fail-
ure. The electronics module is faulty and must be
replaced.
c.Failed J1850 Communication (EVIC only),
BUS (CT, CMTC)- The electronics module is not
receiving proper message input through the J1850
PCI data bus circuit. This can result from one or
more faulty electronic modules in the vehicle, or from
a faulty PCI data bus. The use of a DRB IIItscan
tool and the proper Diagnostic Procedures manual
are required for further diagnosis.
NOTE: If the compass functions, but accuracy is
suspect, it may be necessary to perform a variation
adjustment. This procedure allows the compass
unit to accommodate variations in the earth's mag-
netic field strength, based on geographic location.
Refer to Compass Variation Adjustment in the Stan-
dard Procedures section of this group.
NOTE: If the compass reading displays dashes, and
only ªCALº appears in the display, demagnetizing
may be necessary to remove excessive residual
magnetic fields from the vehicle. Refer to Compass
Demagnetizing in the Standard Procedures section
of this group.

STANDARD PROCEDURE - COMPASS
CALIBRATION
CAUTION: Do not place any external magnets, such
as magnetic roof mount antennas, in the vicinity of
the compass. Do not use magnetic tools when ser-
vicing the overhead console.
The electronic compass unit features a self-cali-
brating design, which simplifies the calibration pro-
cedure. This feature automatically updates the
compass calibration while the vehicle is being driven.
This allows the compass unit to compensate for small
changes in the residual magnetism that the vehicle
may acquire during normal use. If the compass read-
ings appear to be erratic or out of calibration, per-
form the following calibration procedure. Also, new
service replacement Electronic Modules (EVIC,
CMTC, CT) must have their compass calibrated
using this procedure. Do not attempt to calibrate the
compass near large metal objects such as other vehi-
cles, large buildings, or bridges; or, near overhead or
underground power lines.
NOTE: Whenever the compass is calibrated manu-
ally, the variance number must also be reset. Refer
to Compass Variation Adjustment in this group.

ELECTRONIC VEHICLE INFO
CENTER
DESCRIPTION
The Electronic Vehicle Information Center (EVIC)
is a module located in the overhead console on some
models. The EVIC module features a large Vacuum
Fluorescent Display (VFD) screen for displaying
information, and back-lit push button switches
labeled C/T (compass/thermometer), RESET, STEP,
and MENU.
The EVIC module contains a central processing
unit and interfaces with other electronic modules in
the vehicle over the Programmable Communications
Interface (PCI) J1850 data bus circuit. The PCI data
bus circuit allows the sharing of sensor information.
This helps to reduce wire harness complexity, reduce
internal controller hardware, and reduce component
sensor current loads. At the same time, this system
provides increased reliability, enhanced diagnostics,
and allows the addition of many new feature capabil-
ities.
The EVIC ªMenuº push button provides the vehicle
operator with a user interface, which allows the
selection of several optional customer programmable
electronic features to suit individual preferences.
Refer toELECTRONIC VEHICLE INFORMA-
TION CENTER PROGRAMMINGin the Standard
Procedures section of this group for more information
on the customer programmable feature options.
If the vehicle is equipped with the optional univer-
sal transmitter transceiver, the EVIC will also dis-
play messages and an icon indicating when the
universal transmitter transceiver is being trained,
which of the three transmitter buttons is transmit-
ting, and when the transceiver is cleared.
Data input for all EVIC functions, including VFD
dimming level, is received through the J1850 PCI
data bus circuit. The EVIC module uses its internal
programming and all of its data inputs to calculate
and display the requested data. If the data displayed
is incorrect, perform the self-diagnostic tests as
described in this group. If these tests prove inconclu-

FULL OPEN SWITCH
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
full open switch. This switch is located on the gear
motor housing (Fig. 8) and is used to signal the
power liftgate module when the liftgate is in the full
open position. Two wires are used from the full open
switch contacts to the gear motor assemblies main
electrical connector.
The full open switch is a serviceable component.
Consult your Mopar parts catalog for a specific part
number.
OPERATION
When the power liftgate reaches the full open posi-
tion, the gear motor housing mounted full open
switch electrical contacts come in contact with each
other. This sends a ground signal to the power lift-

LIFTGATE MOTOR
DESCRIPTION
Vehicles equipped with a power liftgate, utilize a
liftgate gear/motor assembly (Fig. 11). The gear
motor assembly consists of a DC motor, hall effect
sensor, engage actuator, full open switch, lift gear,
aluminum housing, drive gears and wire harness.
The gears and motor portion of the assembly pro-
vides the power and torque required to open or close
the liftgate under the worst case conditions. The hall
effect sensor is used to provide the liftgate control
module with a speed reading, which is used to mon-itor the resistance of liftgate travel. This speed read-
ing also allows the power liftgate control module to
detect obstructions and move the liftgate accordingly.
The engage actuator is used to toggle between power
open/close mode and full manual mode when desired.
The full open switch is used to let the power liftgate
control module know when the liftgate is approach-
ing the full open position.
Serviceable components of the power liftgate gear/
motor assembly are the complete gear/motor assem-
bly, motor and wire harness, lift gear and control rod,
engage actuator, full open switch and the transverse
bracket. Refer to additional information in this group
for more component details.
OPERATION
With the push of a power liftgate command switch
(liftgate closed), the power liftgate control module
will signal the latch assembly to release the door
from its primary closed and latched position to the
released and movable position. The liftgate motor-
mounted engage actuator then engages the liftgate
motor assembly, which moves the liftgate into the
open position. The liftgate motor provides the torque
and power to move the door to its full open or closed
position(Refer to 8 - ELECTRICAL/POWER DOORS -
OPERATION) for additional information.
REMOVAL
The power liftgate gear/motor assembly is serviced
in two ways: the complete gear/motor assembly, or
the motor, aluminum housing, drive gears and wire
harness assembly. To perform this service, use the
following procedure to remove the gear/motor assem-
bly from the vehicle. Then refer to the other proce-
dures called out this section to transfer the
remaining components (engage actuator, full open
switch, transverse bracket and lift gear and rod) to
the replacement gear/motor assembly.
(1) Disconnect and isolate the negative battery
cable.
(2)
Remove the left rear D-pillar trim panel from the
vehicle. Refer to the Body section for the procedure.
(3) Disconnect the wire harness connector from the
motor assembly (Fig. 11).
(4) Remove the two bolts from the motor housing
and the one bolt from the transverse mount bracket.
(5) Grab the liftgate motor assembly and lift
upward and out to unhook the motor assembly from
the D-pillar.
(6) Remove the liftgate motor assembly from the
vehicle.

PINCH SENSOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize two
pinch sensors, one is located on each side of the lift-
gate (Fig. 14). These sensors look like weather-strips,
however they consist of pieces of electrically conduc-
tive rubber (tapeswitch), wires, resistor, double sided
tape, and a plastic carrier. They are used to indicate
an obstruction during a power close cycle.
OPERATION
During a power liftgate close cycle, if either of the
two conductive rubber strips (tapeswitch) of thepinch sensor come in contact with an obstacle, the
pinch sensor circuit is completed. This tells the
power liftgate control module that a obstruction is
felt. The control module will stop the liftgate imme-
diately and return it to the full open position.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove trim panel from liftgate. Refer to Body
for the procedure.
(3) Disconnect the pinch sensor wire harness con-
nector (Fig. 14).
(4) Remove screws holding the pinch sensor to lift-
gate.
(5) Feed the pinch sensor wire harness out of the
liftgate and remove the sensor from the vehicle.
INSTALLATION
WARNING: USE EXTREME CAUTION WHEN TEST-
ING PINCH SENSOR OPERATION.
(1) Position the pinch sensor and install screws
holding the sensor to the liftgate. Torque screws to
25 in. lbs.
(2) Install wire harness grommet in liftgate flange
and route, connect the pinch sensor wire harness
connector.
(3) Install the trim panel on the liftgate. Refer to

(4) Connect the negative battery cable.
(5) Using an appropriate scan tool, check and
erase any power liftgate control module diagnostic
trouble codes related to the pinch sensor.
(6) Verify power liftgate system and pinch sensor
operation. Cycle the power liftgate through one com-
plete open and close cycle, during the final close cycle
press the pinch sensor to verify the power liftgate
detects an obstruction and returns to the full open
position.
