PRECAUTIONS
 If the following components are replaced with non-genui
ne components or converted, VDC OFF indicator
lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorber, strut, spring, bushing, etc.), Tires, wheels (exclude specified size),
components related to brake (pad, rotor, caliper, etc. ), components related to engine (muffler, ECM, etc.),
components related to body reinforcement (roll bar, tower bar, etc.).
 Driving in the condition of breakage or excessive wear of suspension, tires or components related to the
brakes may cause VDC OFF indicator lamp and SLIP indicator lamp turn on, and the VDC system may not
operate properly.
 When the TCS or VDC is activated by sudden accele ration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.
 When driving on roads which have extreme slopes (s uch as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate nor mally, or VDC OFF indicator lamp and SLIP indi-
cator lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after restart-
ing engine.
 Sudden turns (such as spin turns, acceleration turns) , drifting, etc. When VDC function is OFF (VDC OFF
SW ON) may cause the G sensor system indicate a malf unction. However, this is not a malfunction, if nor-
mal operation can be resumed after restarting engine.
 Change 4 tires at a time. Be sure to use specified- size tires that have the same brand name and pattern.
Wheel sensor errors can be detected be self-diagnosis when tires have wide abrasion variations or the size
is different from the genuine tires.

Adjustment of Steering Angl
e Sensor Neutral PositionINFOID:0000000001327658
In case of doing work that applies to the list below, make sure to adjust neutral position of steering angle sen-
sor before running vehicle.
CAUTION:
To adjust neutral position of steering angl e sensor, make sure to use CONSULT-III.
(Adjustment can not be done without CONSULT-III.)
1. Stop vehicle with front wheels in straight-ahead position.
2. Touch “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-III screen in this order.
3. Touch “START”. CAUTION:
Do not touch steering wheel whil e adjusting steering angle sensor.
4. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
5. Turn ignition switch OFF, then turn it ON again. CAUTION:
Be sure to perform above operation.
6. Run vehicle with front wheels in straight-ahead position, then stop.
7. Select “DATA MONITOR”, “SELECTION FROM ME NU”, and “STR ANGLE SIG” on CONSULT-III screen.
Then make sure “STR ANGLE SIG” is within 0 ± 3.5 deg. If value is more than specification, repeat steps
1 to 6.
8. Erase memory of ABS actuator and electric unit (control unit) and ECM.
9. Turn ignition switch OFF.
Calibration of Decel G Sensor (AWD Models)INFOID:0000000001327659
NOTE:
After removing/installing or replacing yaw rate/side/dec el G sensor, ABS actuator and electric unit (control
unit), suspension components, or after adjusting wheel ali gnment, make sure to calibration of decel G sensor
before running vehicle.
CAUTION:
To calibrate decel G sensor, make sure to use CONS ULT-III. (Adjustment can not be done without CON-
SULT-III.)
1. Stop vehicle with front wheels in straight-ahead position.
CAUTION:
 The work should be done at a horizontal place when vehicle is in the unloaded vehicle condition.
 Keep all tires inflated to correct pressures. Ad just the tire pressure to the specified pressure
value.
2. Touch “WORK SUPPORT” and “DECEL G-SEN CALI BRATION” on CONSULT-III screen in this order.
3. Touch “START”. CAUTION:
Set vehicle as shown in the display.
4. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
