C: CAUTION
Please clearly understand and adhere to the follow-
ing general precautions. They must be strictly fol-
lowed to avoid any injury to the person doing the
work or people in the area.
1. OPERATION
•Wear work clothing, including a cap, protective
goggles and protective shoes during operation.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust and dirt.
•Before disconnecting connectors of sensors or
units, be sure to disconnect the ground cable from
the battery.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
•Be careful not to burn yourself, because each
part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shop jacks or rigid racks at the specified
points.
2. OIL
When handling oil, follow the rules below to prevent
unexpected accidents.
•Prepare container and waste cloths when per-
forming work which oil could possibly spill. If oil
spills, wipe it off immediately to prevent from pene-
trating into floor or flowing outside, for environmen-
tal protection.
•Follow all government and local regulations con-
cerning waste disposal.
3. BRAKE FLUID
If brake fluid gets in your eyes or on your skin, do
the following:
•Wash eyes and seek immediate medical atten-
tion.
•Wash your skin with soap and then rinse thor-
oughly with water.
Follow all government and local regulations con-
cerning waste disposal.

D: ADJUSTMENT
When the following replacement, removal and in-
stallation are performed, be sure to perform center-
ing of the steering angle sensor and zero point
setting of the yaw rate & G sensor.
•VDCCM&H/U
•Steering angle sensor
•Yaw rate & lateral G sensor
•Steering wheel parts (Including airbag)
•Suspension parts
•Wheel alignment adjustment
1) Park the vehicle straight on a level surface. (En-
gine operation in the “P” or “N” range)
2) Check that steering wheel is positioned at the
center. (When the center position is not correct, ad-
just the wheel alignment.)
3) Set the Subaru Select Monitor to the vehicle,
and select {Set up mode for Neutral of Steering An-
gle Sensor & Lateral G Sensor 0 point} in the
“Function check sequence” screen. (Follow the
procedures shown in the display.)
4) On the “Brake Control System” display screen,
select {Current Data Display & Save}, and check
that the steering angle sensor shows “0 deg”.
5) When the “0 deg” is not displayed, repeat the
above steps and check that the “0 deg” is dis-
played.
6) Drive the vehicle for 10 minutes, and check that
the ABS and VDC warning light is not illuminated.
7) Check that there is no unnecessary VDC opera-
tion or steering control loss. If there is a problem,
repeat the steps above.

Yaw Rate & Lateral G Sensor
VEHICLE DYNAMICS CONTROL (VDC)
5. Yaw Rate & Lateral G Sensor
A: REMOVAL
1) Disconnect the ground cable from the battery.
2) Remove the console box.

3) Disconnect the connector from the yaw rate & G
sensor.
4) Remove the yaw rate & G sensor.
CAUTION:
Do not drop or bump the yaw rate & G sensor.
B: INSTALLATION
Install in the reverse order of removal.
NOTE:
Install the yaw rate & G sensor to the body while
pointing the arrow mark on the sensor to the front of
the vehicle.
Tightening torque:
7.5 N·m (0.76 kgf-m, 5.5 ft-lb)
CAUTION:
After completion of installation, set the follow-
ing two positions.
•Positioning to the center of steering angle
sensor
•Positioning of the yaw rate & lateral G sen-
sors to zero.
The above procedure is required VDCCM&H/U
to identify the vehicle position afterward. For
the setting procedures of the 2 steps above, re-
fer to “VDC Control Module & Hydraulic Control
Unit (VDCCM&H/U)”. MENT, VDC Control Module & Hydraulic Con-
trol Unit (VDCCM&H/U).>

CAUTION:
•Do not perform the removal except when the
replacement.
•When replacing more than three times, re-
place the combination switch as assembly to
protect the threads.
1) Set the steering wheel in a straight-ahead posi-
tion.
2) Disconnect the ground cable from the battery.
3) Remove the airbag module.

WARNING:
Always refer to “Airbag System” when perform-
ing the airbag module repair service.

4) Remove the steering wheel.

5) Remove the screws and remove the steering
column lower cover.
6) Remove the two screws securing the steering
column upper cover.
7) Unlock the harness band and disconnect the
connector of the steering angle sensor.
8) Remove the screws which secure the roll con-
nector to steering column.
9) Remove the steering angle sensor from roll con-
nector.
10) Turn the protrusion portion of new steering an-
gle sensor to match the alignment mark of inspec-
tion hole.

C: INSPECTION
1. CHECK WITH SUBARU SELECT MONI-
TOR
1) Connect the Subaru Select Monitor to the data
link connector.
2) Select {Current Data Display & Save}. Check if
the speed indicated on the display changes in the
same manner as the speedometer reading during
acceleration/deceleration when the steering wheel
is in the straight-ahead position.
3) If the speed indicated on the display does not
change, check the ABS wheel speed sensor. to VDC-22, ABS WHEEL SPEED SENSOR, IN-
SPECTION, Front ABS Wheel Speed Sensor.>

1) Check the tip of the ABS wheel speed sensor for
foreign particles or damage. If necessary, clean the
tip or replace the ABS wheel speed sensor.
2) Connect a 12 V power supply to No. 2 terminal of
sensor connector as shown in the figure, then at-
tach resistance to the No. 1 terminal. Rotate the
wheel at about 2. 75 km/h (2 MPH), and measure
the voltage using an oscilloscope.
