Repair Instruction - Initialization
INITIALIZATIONThe initialization procedures are given.
System Name
Variable Gear Ratio Steering System
Meter / Gauge System
1. STEERING ANGLE SENSOR INITIALIZATION
a. Turn the ignition switch ON and check that the VGRS and VSC/TRAC warning lights illuminate for a few seconds.
NOTE: If the warning lights remain on or blink, repair the applicable system.
b. Drive the vehicle on a straight road at 35 km/h (22 mph) or more for 5 seconds or longer. At this point, the steering wheel will still remain off-center by 5 to 10°.
HINT: In this step, the neutral position of the steering wheel is restored from the VGRS ECU memory.
c. After performing normal cornering 2 to 3 times, the steering wheel position is automatically corrected.
NOTE: If the steering wheel remains off-center after the above procedure, repair the applicable system.
d. Confirm that the steering angle sensor initialization is completed.
WHEN USING INTELLIGENT TESTER:
Use this procedure to center the steering wheel when the STRAIGHT ANG FLG from the VGRS DATA LIST reads VALID.
WHEN NOT USING INTELLIGENT TESTER:
1. Drive the vehicle on a road at 60 km/h (37 mph) or more for 30 seconds or longer.
HINT: At this time, if the steering angle initialization is not completed, the VGRS system is stopped.
2. Stop the vehicle with the engine running.
3. Slowly turn the steering wheel from lock to lock.
HINT: Allow 2 seconds or more for 1 turn.
4. If it rotates approximately 2.4 turns, the steering angle sensor initialization is completed. If it rotates approximately 3.5 turns, the steering angle sensor initialization is not completed.
2. RESET COMPASS IN COMBINATION METER
a. 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 glareproof / non-glare proof switch on the inner mirror.
b. SETTING ZONE
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. The zone setting can be changed using the mode select switch of the inner mirror.
c. PERFORMING CALIBRATION
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.
d. 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 calibration cannot be completed despite driving the vehicle in a circle several times, the vehicle's magnetic field may be interfering with the calibration. Demagnetize the vehicle using a demagnetizer and perform calibration again.
e. SETTING COMPASS
f. SELECTING DISPLAY MODE
1. Turn the ignition switch ON.
2. Check that the LED on the inner mirror is lit (green).
3. Check that the compass display indicates an azimuthal direction (N, NE, E, SE, S, SW, W, or NW) or "C".
4. 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 activating the nonglare- proof mode. However, when the switch remains pressed, the LED is lit again after 3 seconds and the system enters the automatic glare-proof mode.
- Continuing to press the mode select switch for 3 seconds after selection of the compass display mode will activate the zone setting mode, showing a number (1-15) on the compass display.
g. ZONE SETTING MODE
Pressing the mode select switch for 6 seconds from the normal mode will activate the zone setting mode, showing a number (1-15) on the compass display.
HINT: In the initial status "8" is displayed.
1. 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.
2. 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".
h. CALIBRATION SETTING MODE
1. After the set zone is displayed, if the switch remains pressed another 3 seconds, it will activate the calibration setting mode.
2. Pressing the switch for 9 seconds from the normal mode will also activate this mode.
3. Drive the vehicle at a slow speed of 8 km/h (5 mph) or less in a circular direction.
4. Driving the vehicle 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 change to "C".
