Dodge Durango (DN). Manual — part 322

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

compass

mini-trip

computer

modules must have their compass calibrated using
this procedure. Do not attempt to calibrate the com-
pass near large metal objects such as other vehicles,
large buildings, or bridges; or, near overhead or
underground power lines.

NOTE: Whenever the compass is calibrated manu-
ally, the variation number must also be reset. See
Compass Variation Adjustment in the Service Pro-
cedures section of this group.

Calibrate the compass manually as follows:
(1) Turn the ignition switch to the On position. If

the compass/temperature data is not currently being
displayed, momentarily depress and release the Step
push button to step through the display options until
you have reached the compass/temperature display.

(2) Depress both the U.S./Metric and the Step

push buttons. Hold the push buttons down until
“CAL” appears in the display. This takes about ten

seconds, and appears about five seconds after “VAR”
is displayed.

(3) Release both of the push buttons.
(4) Drive the vehicle on a level surface, away from

large metal objects and power lines, through three or
more complete circles in not less than 48 seconds.
The “CAL” message will disappear from the display
to indicate that the compass is now calibrated.

NOTE: If the “CAL” message remains in the dis-
play, either there is excessive magnetism near the
compass, or the unit is faulty. Repeat the calibration
procedure at least one more time.

NOTE: If the wrong direction is still indicated in the
compass display, the area selected for calibration
may be too close to a strong magnetic field. Repeat
the calibration procedure in another location.

COMPASS DEMAGNETIZING

A degaussing tool (Special Tool 6029) is used to

demagnetize, or degauss, the overhead console for-
ward mounting screw and the roof panel above the
overhead console. Equivalent units must be rated as
continuous duty for 110/115 volts and 60 Hz. They
must also have a field strength of over 350 gauss at 7
millimeters (0.25 inch) beyond the tip of the probe.

To demagnetize the roof panel and the overhead

console forward mounting screw, proceed as follows:

SERVICE PROCEDURES (Continued)

(1) Be certain that the ignition switch is in the Off

position, before you begin the demagnetizing proce-
dure.

(2) Connect the degaussing tool to an electrical

outlet, while keeping the tool at least 61 centimeters
(2 feet) away from the compass unit.

(3) Slowly approach the head of the overhead con-

sole forward mounting screw with the degaussing
tool connected.

(4) Contact the head of the screw with the plastic

coated tip of the degaussing tool for about two sec-
onds.

(5) With the degaussing tool still energized, slowly

back it away from the screw. When the tip of the tool
is at least 61 centimeters (2 feet) from the screw
head, disconnect the tool.

(6) Place a piece of paper approximately 22 by 28

centimeters (8.5 by 11 inches), oriented on the vehicle
lengthwise from front to rear, on the center line of
the roof at the windshield header (Fig. 3). The pur-
pose of the paper is to protect the roof panel from
scratches, and to define the area to be demagnetized.

(7) Connect the degaussing tool to an electrical

outlet, while keeping the tool at least 61 centimeters
(2 feet) away from the compass unit.

(8) Slowly approach the center line of the roof

panel at the windshield header, with the degaussing
tool connected.

(9) Contact the roof panel with the plastic coated

tip of the degaussing tool. Be sure that the template
is in place to avoid scratching the roof panel. Using a
slow, back-and-forth sweeping motion, and allowing
13 millimeters (0.50 inch) between passes, move the
tool at least 11 centimeters (4 inches) to each side of
the roof center line, and 28 centimeters (11 inches)
back from the windshield header.

(10) With the degaussing tool still energized,

slowly back it away from the roof panel. When the
tip of the tool is at least 61 centimeters (2 feet) from
the roof panel, disconnect the tool.

(11) Calibrate the compass and adjust the compass

variance. Refer to Compass Variation Adjustment
and Compass Calibration in the Service Proce-
dures section of this group for the procedures.

REMOVAL AND INSTALLATION

OVERHEAD CONSOLE READING AND
COURTESY LAMP LENS

REMOVAL

(1) Disconnect and isolate the battery negative

cable.

(2) Insert a long, narrow, flat-bladed tool between

the edge of the reading and courtesy lamp lens and
the overhead console housing just inboard of the lens
pivots (Fig. 4).

(3) Gently pry downward against the reading and

courtesy lamp lens until the pivot of the lens is dis-
engaged from the pivot pin in the lens opening of the
overhead console housing.

(4) Repeat the procedure to disengage the second

lens pivot from its pivot pin.

(5) Pull the pivot end (inboard side) of the reading

and courtesy lamp lens horizontally inboard far
enough to disengage the switch actuator tab on the
outboard side of the lens from the overhead console
housing.

(6) Remove the reading and courtesy lamp lens

from the overhead console housing.

SERVICE PROCEDURES (Continued)

INSTALLATION

(1) Position the switch actuator tab on the out-

board side of the reading and courtesy lamp lens into
the lens opening of the overhead console housing.
The lens actuator tab should be positioned directly
over the switch plunger, which is located just out-
board of the lens opening.

(2) Align the two pivots on the inboard side of the

reading and courtesy lamp lens with the two pivot
pins on the inboard end of the lens opening in the
overhead console housing.

(3) Push firmly and evenly upward on the reading

and courtesy lamp lens directly over each of the two
pivots until they snap into place over the pivot pins
in the lens opening of the overhead console housing.

(4) Reconnect the battery negative cable.
