COMPASS
PRE-CHECK
1. SELECTING COMPASS DISPLAY MODE
The mode select switch allows you to select a Display or Non-display mode of the compass.
The mode select is operated by the automatic glare-proof / non-glare proof switch on the inner mirror.
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 mode select switch of the inner mirror.
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. SELECTING DISPLAY MODE
(a) Turn the ignition switch ON.
(b) Check that the LED on the inner mirror is lit (green).
(c) Check that the compass display indicates an azimuthal direction (N, NE, E, SE, S, SW, W, or NW) or
ºCº.
(d) Pressing the mode select switch on the inner mirror for 3 sec. or more erases the above mentioned
display and activates the Non-display mode.
HINT:
Immediately after pressing the mode select switch, the LED goes off activating the Non-glare-proof
mode. However, when the switch remains pressed, the LED is lit again after 3 sec. and the system
enters the automatic glare-proof mode.
Keep pressing the mode select switch for 3 sec. after selection of the compass display mode will acti-
vate the zone setting mode, showing a number (1-15) on the compass display.

3. INSPECT ENGINE ROOM R/B RELAY CIRCUIT (See
Pase BE-15)
HINT:
The mirror heater relay is built in engine room junction block.
Also the relay is constructed with a relay block that is in the junc-
tion block as a unit. To disconnect the wire harness connecting
with relay block is impossible. If the relay has a malfunction, re-
place it with junction block assembly wire harness together.
4. 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 in-
gredients.
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.
(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. 5VOkay (No break in wire)
Approx. 10V or 0VBroken 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 battery to 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 voltage gradually increases
to about 12 V as the meter probe moves to the other end.
