GENERAL INFORMATION

Following are general descriptions of major compo-

nents used in the Dakota overhead console. Refer to

Group 8W - Wiri ng Diagrams for complete circuit de-

scriptions and diagrams.

COMPASS

The compass will display the direction in which the

vehicle is pointed using the eight major compass

headings (Examples: north is N, northeast is NE). It

does not display the headings in actual degrees. The

display is turned on or off using the COMP/TEMP

button to the left of the display.

The self-calibrating compass unit requires no ad-

justing in normal use. The only calibration that may

prove necessary is to drive the vehicle in 3 complete

circles, on level ground, in not less than 48 seconds.

This will reorient the unit to its vehicle.

The unit also will compensate for magnetism the

body of the vehicle may acquire during normal use.

However, avoid placing anything magnetic directly on

the roof of the vehicle. Magnetic mounts for an an-

tenna, a repair order hat, or a funeral procession flagcan exceed the compensating ability of the compass

unit if placed on the roof panel. Magnetic bit drivers

used on the fasteners that hold the assembly to the

roof header can also affect compass operati on.I f the vehicle roof should become magnetized, the

demagnetizing and calibration procedures may be re-quired to restore proper operation.

THERMOMETER

The thermometer displays the outside ambienttemperature. The temperature displayed can bechanged from Fahrenheit to Celsius using the US/

METRI C button. The displayed temperature is notan i nstant reading of conditions, but an average tem-perature. I t may take the unit several minutes to re-act to a major temperature change such as drivingout of a heated garage into winter temperatures.

When the ignition switch is turned OFF, the lastdisplayed temperature reading stays in memory.When the ignition switch is turned ON again, thethermometer will display the memory temperaturefor one minute; then update the display to the cur-rent average temperature reading within five min-utes.

READINGAND COURTESY LAMPSAll reading and courtesy lamps in the overhead

console are activated by the door jamb switches.When both doors are closed, the lamps can be indi-vidually activated by depressing the correspondinglens. When a door is open, depressing the lamp lensswitches wil l not turn the lamps off. Refer to Group8L - L amps, for diagnosis and service of these lamps.

REMOTE GARAGE DOOR OPENER STORAGE

A compartment in the overhead console is designedto hold most remote garage door opener transmitters.

The transmitter is mounted within the compartmentwith an adhesive-backed hook and loop fastenerpatch. Then one to three pegs are selected andmounted in a slot on the i nside of the storage com-partment door. The pegs may be stacked, if neces-sary. The peg(s) selected must be long enough toactivate the button of the transmitter each time the

storage compartment door is depressed.

SUNGLASSES STORAGE

A flocked storage compartment for sunglasses is in-

cluded in the overhead console. This compartment

features a push/push-type latch and a viscous damp-

ening system for a flui d opening motion.

DIAGNOSIS

COMPASS/DISPLAY SELF-DIAGNOSTIC TEST

This self-diagnostic test is used to determine thatthe compass and all of its display segments are oper-ating properly electri cally. There are three self-diag-nostic tests available. They are:

(1) A magnetic field strength test that shows thestrength of the magnetic fi elds being received at thecompass uni t fluxgate.

(2) An internal electronics test that checks the in-ternal electronic circuitr y of the compass unit.

(3) A walking segment test that checks the opera-tion of each of the segments used in the electronicdisplay.

I nitiate the self-diagnostic test as follows:(1) With the ignition switch in the OFF position,

depress and hold the COMP /TE MP button. Whilestill holding the COMP /TEMP button depressed, turnthe ignition switch to the ON position. The displaywill show d0 to indicate the unit is in the diagnos-tics mode.

(2) Before beginning the magnetic field strength

test, get a pencil and a piece of paper. To begin thistest, momentarily depress and release the US/ME T-RI C button one time. The following will occur: The letter N will be shown in the compass portionof the display. A number that equals the magneticfield strength in the north/south direction appears inthe temperature portion of the display. Note thisnumber on your paper. The letter W will be shown in the compass portionof the display. A number that equals the magneticfield strength in the east/west direction appears inthe temperature portion of the display. Note thisnumber on your paper.

The display will read d1 to i ndicate the fir st di-agnostic test is completed.

For proper compass operati on, the numbers shownshould be between 1 and 14. A number of 7 or 8 isideal (no vehicle magnetism present). Numbers closerto 1 or 14 show that the vehicle is highly magnetic. I fthe test shows the vehicle is highly magnetic, the ve-hicle needs to be demagnetized. See Compass Demag-netizing in this group.

(3) To begin the internal electronic circuitry test,momentarily depress and release the US/METRI Cbutton one time. T he display will go blank as the testbegins. I f the test is passed, the display will readd2. I f the display reads f2, the unit is faulty andmust be replaced.

(4) To begin the walki ng segment test, momen-tarily depress and release the US/METRI C buttonone time. The display will illuminate each directionand number until all segments have been used. T hedisplay will read d3 when the test is complete. Ifany segment should fail to light during the test, theunit is faulty and requires replacement.

(5) Momentarily depress and release the US/ME T-RI C button one time, or turn the ignition switch toOFF to exit the self-diagnostic mode and return tonormal operati on.

If the compass functions, but accuracy is sus-pect, it may be necessary to perform a variationadjustment. T his procedure allows the unit toaccommodate variations in the earths mag-netic field strength based on geographic loca-tion. See Compass Variation Adjustment, in thisgroup.

If the compass display has blanked out and

only CAL appears, demagnetizing may be nec-essary to remove excessive residual magneticfields from the vehicle. See Compass Demagne-tizing, in this group.

COMPASS/THERMOMETER DIAGNOSIS



4/10

THERMOMETER DIAGNOSIS

The thermometer function is supported by a tem-

perature sensor, a wiring circuit and a portion of the

overhead console display. The sensor is mounted at

the center of the vehicle on the support brace, behind

the grille (Fig. 1).

I f any portion of the circuit fails, it will self-diag-

nose as an open or short circuit. The system will dis-

play SC (short circuit) when the sensor is exposed totemperatures in excess of 55C (131F) or if the cir-

cuit is shorted. I f the temperature is below -40C

(-40F) or an open circuit exists, the system will dis-

play OC (open circuit).

To diagnose the temperature sensor, perform the

following procedures. I f the sensor and circuit are

OK , then the electronic module is faulty and should

be replaced.

SENSOR TEST

(1) Turn the ignition switch to OFF. U nplug sensorconnector.

(2) Measure resistance of sensor. At -40F the re-sistance is 336K ohms. At 140F the resistance is2.488K ohms. Sensor resistance should read betweenthese two values. If OK, go to Sensor Circuit Test. If

not OK , replace the sensor.

SENSOR CIRCUIT TEST

(1) Turn ignition switch to OFF. Unplug sensorconnector.

(2) Short the pins on the body half of connector us-ing a jumper wire.

(3) Remove the overhead console as described inService Procedures.

(4) Check continuity between cavities 6 and 8 ofoverhead console harness connector (Fig. 2). Thereshould be continuity. I f OK, go to next step. I f notOK , repair open circuit as required.

(5) Remove jumper wire from temperature sensorharness connector. Check continuity between cavities6 and 8 of overhead console harness connector (Fig.2) and a good ground. There should be no continuity.I f OK , replace electronic module. If not OK, repairshort circuit as required.

SERVICE PROCEDURES

COMPASS VARIATIONADJUSTMENT

Variance is the difference between magnetic north

and geographic north. I n some areas, the difference

between magnetic and geographic north is great

enough to cause the compass to give false readings. If

this occurs, the variance must be set.To set the variance:

(1) Using the map in Fig. 1, find your geographic

location and note the zone number.

(2) Turn ignition switch to the ON position.

(3) Depress both the US/MET RIC and COMP/

TE MP buttons. Hold down until VAR is displayed.

This takes about 5 seconds.

(4) Release both buttons.(5) Press the US/METRI C button to step through

the numbers until the zone number for your area ap-

pears in the display.

(6) Press the COMP/TE MP button to enter this

zone number into compass unit memory.

(7) Confirm correct directions are indicated.

COMPASS CALIBRATION

CAUTION: DO NOT place any external magnets

such as magnetic roof mount antennas, in the vicin-

ity of the compass. DO NOT use magnetic tools

when servicing the overhead console.

The compass features a self-calibrating design,

which simplifies the calibration procedure. Thi s fea-

ture automatically updates the compass calibrationwhile the vehicle is being driven. This takes into ac-

count small changes in residual magnetism the vehi-

cle may acquire during normal use. Do not attempt

to calibrate the compass near large metal objects

such as other vehicles, large buildings or bridges.

Whenever the compass is calibrated manually,

the variation number must also be r eset. See

Variation Adjustment Procedure, in this group.

Calibrate the compass manually as follows:

(1) Start the engine.

(2) Depress both the US/ME TRIC and COMP/

TE MP buttons. Hold down until CAL is displayed.This takes about 10 seconds and appears about 5 sec-

onds after VAR is displayed.

(3) Release both buttons.

(4) Drive vehicle on a level surface that is away

from large metal objects through 3 or more complete

circles in not less than 48 seconds. T he CAL message

will disappear to indicate that the compass is now

calibrated.

If CAL message remains in display, either

there i s excessive magnetism near the compass

or the unit is faulty. R epeat the demagnetizing

and calibration procedures at least one more

time.

If the wrong direction is still indicated, the

area selected may be too close to a strong mag-

netic field. Repeat the calibration procedure in

another location.

COMPASS DEMAGNETIZING

The tool used to degauss or demagnetize the roof

panel is the Miller Tool 6029. Equivalent units must

be rated as continuous duty for 110/115 volts and

60Hz. They must also have a field strength of over

350 gauss at 1/4-inch beyond the tip of the probe.

The degaussing tool is used to demagnetize the roofpanel, as foll ows:

(1) Be sure the ignition switch is in the OFF posi-

tion before you begin the demagnetizing procedure.

(2) Place an 8-1/2 X 11 inch piece of paper, oriented

lengthwise from front to rear, on the center line of

the roof at the windshield header (Fig. 2). The pur-

pose of the paper is to protect the roof panel from

scratches and define the area to be demagnetized.

(3) Pl ug in the degaussing tool, while keeping the

tool at least 2 feet away from the compass unit.

(4) Slowly approach the center line of the roof

panel at the windshield header with the degaussing

tool plugged in.

(5) Contact the roof panel with the tip of the tool. Be

sure template is in place to avoid scratching the roof

panel. Using a slow, back and forth sweeping motion

and allowing 1/2-inch between passes (Fig. 2), move the

tool at least 4 i nches either side of the roof center line

and 11 inches back from the windshield header.

(6) With the degaussing tool still energized, slowly

back it away from the r oof panel until the tip is atleast 2 feet from the roof. Then unplug the tool.

(7) Calibrate the compass and adjust variance asdescribed in this group.
