CALIBRATION
1. SELECTING COMPASS DISPLAY MODE
The mode select switch allows you to select a Display or Non±display mode of the compass.
2. SETTING ZONE
Deviation between the magnetic north and ºactual northº differs depending on the terrestrial location, there-
fore, an adjustment in magnetism is required. Since the magnetic condition differs according to the area
where the vehicle will be used, it is necessary for each user to set the zone. (Refer to ºCompass Zone Mapº).
The zone setting can be changed using the E/M switch of the display.
3. PERFORMING CALIBRATION
Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This com-
pass function is used when storing the record of the vehicle's magnetic field.
4. WHEN COMPASS MAGNETIZED:
A compass could be magnetized during shipping by vessels or freight cars. Before delivery, therefore, make
sure to perform calibration and ensure that calibration can be done. If it cannot be done (cannot complete
in spite of driving round several times), it may be caused by magnetization. Demagnetize the vehicle using
a demagnetizer and perform calibration again.

6. ZONE SETTING MODE
(a) Turn the ignition switch ON.
(b) Keep pressing the E/M switch and MODE switch for 5 sec. when outer temperature is displayed, will
activate zone setting mode, showing a number (1±15) on the compass display.

HINT:
In the initial status, º8º is displayed.
(c) The displayed number increases +1 every time the E/M switch is pressed. Referring to the map, check
the number for the area where the vehicle will be used and set the zone number.
(d) Leave it untouched for several seconds after setting and check that the compass display shows an
azimuthal direction (N, NE, E, SE, S, SW, W, or NW) or ºVARº.
7. CALIBRATION SETTING MODE
(a) After the set zone is displayed, if the E/M switch and MODE switch remains pressed for another 5 se-
conds, calibration setting mode will be activated.
(b) Keep pressing the E/M switch and MODE switch for 10 sec. when outer temperature is displayed will
also activate this mode.
(c) Drive the vehicle at a speed of 5 MPH (8 km/h) or less in a circle.
(d) Driving in a circle 1 to 3 times will display the azimuthal direction on the display, completing the calibra-
tion.
HINT:
Once calibration is completed, it is not necessary to perform the above procedures unless the magnetic field
strength is drastically changed. If this happens, the azimuthal display will be changed to ºCALº.

INSPECTION
1. Connecter connected:
INSPECT DEFOGGER TIMER OPERATION
(a) Connect the positive (+) lead from the voltmeter to termi-
nals 1, 2 and 7 of the panel switch connector and the neg-
ative (±) lead to terminal 10.
(b) When the switch is OFF, the voltage should be approx.
12 V.
(c) Turn the defogger switch ON and check that the indicator
comes on and that the voltage is less than 1 V.
(d) After 15 minutes, check that the switch is OFF and the
voltage is approx. 12 V.
If operation is not as specified, replace the switch.
2. Connector disconnected:
INSPECT DEFOGGER SWITCH (in INTEGRATION
CONTROL PANEL SWITCH) CIRCUIT
Disconnect the connector from the panel switch and inspect the
connector on the wire harness side, as shown in the chart be-
low.

5. INSPECT DEFOGGER WIRE
NOTICE:
When cleaning the glass, use a soft, dry cloth, and
wipe the glass in the direction of the wire. Take care
not to damage the wires.
Do not use detergents or glass cleaners with abrasive
ingredients.
When measuring voltage, wrap a piece of tin foil
around the tip of the negative probe and press the foil
against the wire with your finger, as shown in the il-
lustration.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each heat wire, as
shown.
VoltageCriteria
Approx. 5 VOkay (No break in wire)
Approx. 10 V or 0 VBroken wire
HINT:
If there is approximately 10 V, the wire is broken between the
center of the wire and the positive (+) end. If there is no voltage,
the wire is broken between the center of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
wire on the battery side.
(e) Place the voltmeter negative (±) lead with the foil strip
against the wire on the ground side.
(f) Slide the positive (+) lead from the battery to the ground
side.
(g) The point where the voltmeter deflects from several V to
zero V is the place where the defogger wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but gradually increases to about
12 V as the meter probe moves to the other end.
