ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION
DescriptionINFOID:0000000006222588
Always adjust the neutral position of steering angle sensor before driving when the following operation is per-
formed.
× : Required —: Not required
Work ProcedureINFOID:0000000006222589
ADJUST THE NEUTRAL POSITION OF STEERING ANGLE SENSOR
CAUTION:
Always use CONSULT-III when adju sting the neutral position of steering angle sensor. (It cannot be
adjusted other than with CONSULT-III.)
1.CHECK THE VEHICLE STATUS
Stop vehicle with front wheels in the straight-ahead position.
Does the vehicle stay in the straight-ahead position?
YES >> GO TO 2.
NO >> Steer the steering wheel to the st raight-ahead position. Stop the vehicle.
2.ADJUST NEUTRAL POSITION OF STEERING ANGLE SENSOR
With CONSULT-III.
1. Turn the ignition switch ON.
CAUTION:
Never start engine.
2. Select “ABS”, “WORK SUPPORT” and “ST AN GLE SENSOR ADJUSTMENT” in this order.
3. Select “START”. CAUTION:
Never touch steering wheel while adjusting steering angle sensor.
4. After approx. 10 seconds, select “END”.
5. Turn ignition switch OFF and then turn it ON again. CAUTION:
Be sure to perform the operation above.
>> GO TO 3.
3.CHECK DATA MONITOR
With CONSULT-III.
1. The vehicle is either pointing straight ahead or t he vehicle needs to be moved. Stop when it is pointing
straight ahead.

Decel G sensor calibration
CAUTION:
Always use CONSULT-III for the d ecel G sensor calibration. (It cannot be adjusted other than with
CONSULT-III.)
NOTE:
Yaw rate/side/decel G sensor calibration is performed when performing the decel G sensor calibration.
1.CHECK THE VEHICLE STATUS
1. Steer the steering wheel to the straight- ahead position. Stop the vehicle on level surface.
2. Stop the engine.
3. Turn the ignition switch OFF.
Is the vehicle stopped in the straight-ahead position on level surface?
YES >> GO TO 2.
NO >> Steer the steering wheel to the straight- ahead position. Stop the vehicle on level surface.
2.PERFORM DECEL G SENSOR CALIBRATION
CAUTION:
 Never allow passenger or load on the vehicle.
 Never apply vibration to the vehicle body when opening or closing door during calibration.
With CONSULT-III.
1. Turn the ignition switch ON.
CAUTION:
Never start engine.
2. Select “ABS”, “WORK SUPPORT”, “DECEL G-SENSOR CALIBRATION” in this order.
3. Select “START”.
4. After approx. 10 seconds, select “END”.
5. Turn ignition switch OFF and then turn it ON again. CAUTION:
Be sure to perform the operation above.

Body Center MarksINFOID:0000000006248507
A mark is placed on each part of the body to indicate the vehicle center. When repairing the vehicle frame
(members, pillars, etc.) damaged by an accident which it enables more accurate and effective repair by using
these marks together with body alignment specifications.
Unit: mm (in)
DescriptionINFOID:0000000006248508
 All dimensions indicated in the figures are actual.
 When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge itself
to make sure there is no free play.

 When a measuring tape is used, check to be su re there is no elongation, twisting or bending.
 Measurements should be taken at the center of the mounting holes.
 An asterisk (*) following the value at the measuring poi nt indicates that the measuring point on the other side
is symmetrically the same value.
 The coordinates of the measurement points are the distances measured from the standard line of ″X ″, ″Y ″
and ″Z ″.
 ″Z ″: Imaginary base line [300 mm (11.81 in) below datum line ( ″0Z ″ at design plan)]

Dimensions marked with ″*″ indicate symmetrically identical dimensions on both the right and left hand of the
vehicle.
