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.

Judge as NG when either the following is completed.
•When the read value of throttle position sensor 1 signal is mismatched between main CPU and sub CPU.
•When the read value of accelerator position sensor 1 signal is mismatched between main CPU and sub
CPU.
•When the sub CPU operates abnormally.
•When the communication between main CPU ←→ sub CPU is abnormal.
•When the input amplifier circuit of throttle position sensor 1 is abnormal.
•When the cruise control cannot be canceled correctly.
•When the signal of brake SW1 and 2 is mismatched.
