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.

Pressing the mode select switch for 6 sec. from the normal mode will activate the zone setting mode, showing
a numbar (1-15) on the compass display.
HINT:
In the initial status, º8º is displayed.
(1) The displayed number increases +1 every time the mode select switch is pressed. Referring to
the map, check the number for the area where the vehicle will be used and set the zone number.
(2) 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 ºCº.
8. CALIBRATION SETTING MODE
(a) After the set zone is displayed, if the switch remains pressed another 3 sec. will activate the calibration
setting mode.
(b) Pressing the switch for 9 sec. from the normal mode will also activate this mode.
(c) Drive the vehicle at a slow speed of 8 km/h (5MPH) or less in the circular direction.
(d) Driving round the circle 1 to 3 times will display the azimuthal direction on the display, completing the
calibration.
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 ºCº.

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.

5. IF NECESSARY, REPAIR DEFOGGER WIRE
(a) Clean the broken wire tips with grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire for
repair.
(c) Thoroughly mix the repair agent (Dupont paste No.
4817).
(d) Using a fine tip brush, apply a small amount of the agent
to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours.
6. w/ Mirror heater:
INSPECT MIRROR HEATER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
5 and the negative (-) lead to terminal 12.
(b) Check that the mirror becomes warm.
HINT:
It will take a short time for the mirror to become warm.
