Compass: Testing and Inspection





MIRROR (INT): INNER REAR VIEW MIRROR: CALIBRATION

1. SELECT COMPASS DISPLAY MODE

(a) The AUTO switch allows you to select whether or not the compass is displayed.

2. SET ZONE

(a) The compass indicates the direction that the vehicle is heading by detecting the direction and strength of the earth's magnetic field (magnetic north). However, there is a difference between magnetic north and actual north that depends on the location of the vehicle. To compensate for this difference, it is necessary to set the zone in which the vehicle will be used (Refer to Compass Zone Map). The zone setting can be changed using the AUTO switch of the inner mirror.

3. PERFORM CALIBRATION

(a) Because each vehicle has its own magnetic field, calibration should be performed. The calibration function is used to compensate for the residual magnetism of the vehicle.

4. WHEN COMPASS IS MAGNETIZED

(a) The compass or vehicle may become magnetized while the vehicle is being shipped. As a result, it is necessary to perform calibration for the compass before the vehicle is delivered to the customer. If calibration cannot be performed successfully (calibration cannot be completed in spite of driving around several times), it may be caused by excessive magnetization of the vehicle. Demagnetize the vehicle using a demagnetizer and perform calibration again.

5. SET COMPASS





HINT
It returns to a normal mode when the AUTO switch is pressed for 12 seconds or more.

6. ZONE SETTING MODE

(a) When the compass is in normal mode, pressing the AUTO switch for 9 seconds will activate zone setting mode. A number from 1 to 15 will be displayed on the compass display.

HINT
If the initial zone setting has not been changed, 8 will be displayed.

(b) The displayed number increases by 1 every time the AUTO switch is pressed. Referring to the map, check the number for the area where the vehicle will be used and set the zone number.

(c) Do not touch the AUTO switch for several seconds after setting the zone. Check that the compass display shows a direction (N, NE, E, SE, S, SW, W or NW). In some cases, the compass may display "CAL".

7. CALIBRATION MODE

(a) When the compass is in normal mode, pressing the AUTO switch for 9 seconds will activate calibration mode.

(b) Drive the vehicle in a circle at a speed of 8 km/h (5 mph) or less.

(c) After driving around in a circle 1 to 3 times, the direction (N, NE, E, SE, S, SW, W or NW) will be displayed on the compass display. This indicates that calibration has finished.

HINT
After calibration is performed, it is not necessary to repeat the calibration procedure unless magnetic field of the vehicle changes drastically. If the magnetic field changes drastically, the compass display will indicate "CAL".
