4. PROBLEM SYSMPTOMS TABLE
NOTICE:
When replacing the internal mechanism (computer part) of the audio system, be careful that no part
of your body or clothing comes in contact with the terminals of the leads from the IC, etc. of the re-
placement part (spare part).
HINT:
This inspection procedure is a simple troubleshooting which should be carried out on the vehicle during sys-
tem operation and was prepared on the assumption of system component troubles (except for the wires and
connectors, etc.).
Always inspect the trouble taking the following items into consideration.
Open or short circuit of the wire harness
Connector or terminal connection fault

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.
7. ZONE SETTING MODE

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.
