Compass: Testing and Inspection
CALIBRATION1. 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. COMPASS ZONE SETTING
Deviation between magnetic north and true north differs depending on the terrestrial location. Therefore, 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 "compass zone map"). The zone setting can be changed using the mode select switch of the inner mirror.
3. COMPASS CALIBRATION SETTING
Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This compass 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 in a circle several times), it may be caused by magnetization. Demagnetize the vehicle using a demagnetizer and perform calibration again.
5. SETTING COMPASS
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 "C".
d. Pressing the mode select switch on the inner mirror for 3 seconds 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 and the non-glare-proof mode activates. However, when the switch remains pressed, the LED is lit again after 3 seconds and the system enters the automatic glare-proof mode.
- Keep pressing the mode select switch for 3 seconds after selection of the compass display mode to activate the zone setting mode. A number (1-15) will be shown on the compass display.
7. ZONE SETTING MODE
Pressing the mode select switch for 6 seconds from the normal mode will activate the zone setting mode. A number (1-15) will be shown on the compass display.
HINT: In the initial status "8" is display.
a. The display 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.
b. Leave it untouched several seconds after setting and check that the compass display shows an azimuthal direction (N, NE, E, SE, S, SW, W, or NW) or "C".
8. CALIBRATION SETTING MODE
a. After the set zone is displayed, if the switch remains pressed another 3 seconds, the calibration setting mode will activate.
b. Pressing the switch for 9 seconds 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 a circular path.
d. Driving in a 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 "C".
