Step Check Yes No
1CHECK STEERING WHEEL.
1) Drive the vehicle on a flat road.
2) Park the vehicle straight.
3) Check the steering wheel for deviation from
center.
Is the deviation from the center
of steering wheel less than 5°?
Go to step 2.Perform the cen-
tering adjustment
of steering wheel.
2CHECK DRIVING PLACE.
Check if the vehicle ran the road with banks or
sandy surface (which does not mean a dirt
road).
Did the vehicle run the road
with banks or sandy surface
(which does not mean a dirt
road)?
VDCCM&H/U may
record DTC when
the vehicle ran the
road with banks or
sandy surface
(which does not
mean a dirt road).
Go to step 3.
3CHECK OUTPUT OF STEERING ANGLE
SENSOR WITH SUBARU SELECT MONI-
TOR.
1) Select {Current Data Display & Save} in
Subaru Select Monitor.
2) Read the steering angle sensor output dis-
played on display.
Does the steering angle sensor
output value on the display
var y in accordance with steer-
ing operation when turning the
steering wheel to the right or
left?
Go to step 4.Replace the steer-
ing angle sensor.
4CHECK THE VDCCM&H/U.
1) Turn the ignition switch to OFF.
2) Connect all the connectors.
3) Erase the memory.
4) Perform the inspection mode.
5) Read the DTC.

Wheel Balancing
WHEEL AND TIRE SYSTEM
4. Wheel Balancing
A: ADJUSTMENT
NOTE:
The balance weight for the outside of the wheel
uses an adhesive type weight. Change the setting
of the wheel balancer to an adhesive type weight.

CAUTION:
•Be careful not to damage the wheel.
•Completely remove the double–sided tape of
the adhesive type weight from the wheel.
2) Using the wheel balancer, measure wheel bal-
ance.
3) Select a weight close to the value measured by
wheel balancer.
CAUTION:
Use SUBARU genuine balance weights.
4) Install the selected weight to the point designat-
ed by the wheel balancer.
CAUTION:
•Remove grease from adhesive type weight
applying surface of wheel.
•Press the adhesive type weight by 25 N (2.5
kgf, 5.6 lb) or more per 5 g (0.18 oz) for more
then 2 seconds and attain full adhesion.
•The total weight of all adhesive weight on
models with transmitters (tire pressure sensor)

Drive Cycle
ENGINE (DIAGNOSTICS)
12.Drive Cycle
A: PROCEDURE
For the troubleshooting, there are five driving pat-
terns of drive cycles A to E. Driving in the specified
pattern allows to diagnose malfunctioning items
listed below. After the repair of the following trouble
items, be sure to drive the vehicle with the specified
drive patterns to check whether the function is re-
sumed correctly.
1. PREPARATION FOR DRIVE CYCLE
1) Check battery voltage is more than 12 V and fuel
remains half [20 to 40 2 (5.3 to 10.6 US gal, 4.4 to
8.8 Imp gal)].
2) After performing the diagnostics and clearing the
memory, check for any remaining unresolved trou-
ble data.
3) Disconnect the test mode connectors.
NOTE:
•Perform the diagnosis after warming up the en-
gine except when the engine coolant temperature
at starting is specified.
•Perform the diagnosis twice if the DTC marked
with *. After completing the first diagnosis, stop the
engine and perform second diagnosis in same con-
dition.

Drive Cycle
ENGINE (DIAGNOSTICS)
5. DRIVE CYCLE D
Drift Diagnosis
1) Check that the engine coolant temperature at engine start is 30°C (86°F) or less.
2) Check that the battery voltage is more than 10.9 V and that more than 9.6 2 (2.5 US gal, 2.1 Imp gal) of
fuel remains.
3) Start the engine, and check that the engine coolant temperature increases over 10°C (50°F), and reaches
75°C (167°F) or more, when the engine is warmed up.
4) After the engine has reached the state of procedure 3), idle the engine for more than 120 seconds.
Stuck Diagnosis
1) Check that the battery voltage is over 10.9 V.
2) Perform the clear memory mode.
3) Drive for approximately 50 2 (13.2 US gal, 11 Imp gal) of fuel.
NOTE:
•It is acceptable to drive the vehicle intermittently.
•Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the bat-
tery terminals.)
6. DRIVE CYCLE E
1) Check that the battery voltage is over 10.9 V.
2) Perform the clear memory mode.
3) Drive for approximately 30 2 (7.9 US gal, 6.6 Imp gal) of fuel.
NOTE:
•It is acceptable to drive the vehicle intermittently.
•Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the bat-
tery terminals.)
7. DRIVE CYCLE F
1) Check that the engine coolant temperature at engine start is 30°C (86°F) or less.
2) Start the engine, and warm it up until engine coolant temperature increases over 95°C (203°F).
3) After the engine has reached the state of procedure 2), idle the engine for more than 10 minutes.
NOTE:
Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the battery
terminals.)
