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.

sor
A: REMOVAL
1) Disconnect the ground cable from the battery.
2) Disconnect the ABS wheel speed sensor con-
nector in the engine compartment.
3) Remove the sensor harness from the clip.
4) Remove the clip which secures the sensor har-
ness to the front strut.
5) Remove the front ABS wheel speed sensor from
housing.
CAUTION:
•Be careful not to damage the sensor.
•Do not apply excessive force to the sensor
harness.
B: INSTALLATION
Install in the reverse order of removal.
Tightening torque:
7.5 N·m (0.76 kgf-m, 5.5 ft-lb)
CAUTION:
Be careful not to damage the sensor.
NOTE:
•Check the identification (mark) on the harness to
make sure there is no warpage. (W1 (White))
•Check if the harness is not pulled and does not
come in contact with the suspension or body during
steering wheel effort.
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.>
