A: REPLACEMENT
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.
ule.>
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.
CAUTION:
Be careful not to allow foreign matter to enter
into inspection hole.
11) Align the center of roll connector.

12) Apply a thin coat of grease that is supplied with
the new part, to the 4 protruding sections of the

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.>

2. 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.
