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.)

NOTE:
The example shown is for the front right wheel. The procedure for the other wheels is the same as given
below.
 When performing an active test of the ABS function, se lect the main item for each test item. In addition,
when performing an active test of the VDC/TCS function, select the item menu for each test item.
 For the ABS solenoid valve, touch “UP” “KEEP” “DOWN”, and for the ABS solenoid valve (ACT), touch “UP”

PRECAUTIONS FOR DIAGNOSIS
 Before performing diagnosis, always read precautions. Refer to BRC-13, "How to Proceed with Diagnosis".
 If ABS actuator and electric unit (control unit), steer ing angle sensor, steering system parts or suspension
system parts have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of
steering angle sensor before driving. Refer to BRC-8, "
Adjustment of Steering Angle Sensor Neutral Posi-
tion".
 After diagnosis is finished, be sure to erase memory. Refer to BRC-26, "
Self-Diagnosis".
 When checking continuity and voltage between units, be sure to check for disconnection, looseness, bend,
or collapse of connector terminals. If any malfuncti on is found, repair or replace connector terminals.
 For intermittent symptoms, possible cause is malfunc tion in harness, harness connector, or terminals. Move
harness, harness connector, and terminals to check for poor connections.
 If a circuit tester is used for the check, be ca reful not to forcibly extend any connector terminal.
 To use CONSULT-III to perform self-diagnosis of ABS act uator and electric unit (control unit), active tests, or
work support, first stop work, then connect CONSULT-III and select “ABS”.
 While self-diagnostic results of CONSULT-III shows malf unction, if CONSULT-III active test is performed, an
engine system error may be indicated. In this case, start engine to resume the normal screen.
 VDC/TCS/ABS system electronica lly controls brake operation and engine output. The following symptoms
may be caused by normal operations:

• When installing rubber bushings, final tightening must be carried out under unladen conditions with tires on
ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
 Unladen conditions mean that fuel, engine coolant and l ubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
 After servicing suspension parts, be sure to check wheel alignment.
 Caulking nuts are not reusable. Always use new ones w hen installing. Since new caulking nuts are pre-oiled,
tighten as they are.
 Avoid burden to front cross bar.
