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.>

C: CAUTION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Remove contamination including dirt and corrosion before removal, installation or disassembly.
•Keep the disassembled parts in order and protect them from dust and dirt.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, 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.
•Before disconnecting connectors of sensors or units, be sure to disconnect the ground cable from battery.
