General Description
AUTOMATIC TRANSMISSION (DIAGNOSTICS)
3. General Description
A: CAUTION
•SRS AIRBAG SYSTEM
The airbag system wiring harness is routed near
the TCM.
CAUTION:
•All air bag system wiring harnesses and con-
nectors are colored yellow. Do not use an elec-
tric test equipment to check these circuits.
•Be careful not to damage the airbag system
wiring harness when performing diagnostics or
servicing the TCM.
•MEASUREMENT
When measuring the voltage and resistance of the
ECM, TCM or each sensor, use a tapered pin with
a diameter of less than 0.64 mm (0.025 in) in order
to avoid poor contact. Do not insert a pin of more
than 0.65 mm (0.026 in) diameter.
B: INSPECTION
1. BATTERY
Measure the battery voltage and specific gravity of
electrolyte.
Standard voltage: 12 V or more
Specific gravity: 1.260 or more
2. TRANSMISSION GROUND
Make sure that the ground terminal bolt is tightened
securely.
Tightening torque:
13 N·m (1.3 kgf-m, 9.4 ft-lb)
3. ATF LEVEL
Make sure that ATF level is the specified amount.
4. FRONT DIFFERENTIAL OIL LEVEL
Make sure the front differential oil level is the spec-
ified amount.

DTC DETECTING CONDITION:
Target gear ratio and actual gear ratio do not match.
TROUBLE SYMPTOM:
•Shift point is too high or too low.
•Excessive shift shock.
•Gear is not changed.
•The vehicle does not move in D or R range with the engine running at high speed.
Step Check Yes No
1CHECK DTC OF TCM.Is any DTC of the followings
detected? P0715, P0720,

Go to step 2.
2CHECK TURBINE SPEED SENSOR USING
SUBARU SELECT MONITOR.
1) Lift-up the vehicle and support with rigid
racks.
NOTE:Raise all wheels off floor.
2) Start the engine, and drive it.
3) Read the current data of torque converter
turbine speed using Subaru Select Monitor.
NOTE:The speed difference between front and rear
wheels may light the ABS warning light, but this
indicates no malfunction. When AT control di-
agnosis is finished, perform the VDC memory
clearance procedure of on-board diagnostics
system.

Does the displayed value of the
Subaru Select Monitor change
according to engine speed and
shifting?
Go to step 3.Perform the diag-
nosis according to
DTC P0715,
P1710.
3CHECK FRONT AND REAR VEHICLE
SPEED SENSORS.
Do the values displayed for
each of the Subaru Select
Monitor and the speedometer
substantially match?
Go to step 4.Perform the diag-
nosis according to
DTC P0720,
P1706.
4CHECK INHIBITOR SWITCH.Do the values displayed for the
Subaru Select Monitor and the
meter indicator match?
Go to step 5.Perform the diag-
nosis according to
DTC P0705.
5DRIVING CHECK.
1) Turn the ignition switch to OFF.
2) After restarting the engine, check that the
SPORT indicator light is not blinking, and per-
form a drive check based on the inspection
mode.
Is DTC displayed again? Check the DTC.
Then, when pro-
ceeded again to
step 5, go to step
6.
Go to step 6.
6CHECK AFTER REPAIR.Is the trouble symptom inre-
pairable (malfunction in shifting
such as excessive shift shock,
engine speed increases exces-
sively when shifting)?
Replace the trans-
mission assembly.
Te m p o r a r y p o o r
contact occurs.
Check that the
harness connec-
tor is not faulty.
