N: DTC P0736 REVERSE INCORRECT RATIO
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,
P0753, P0758, P0763, P0768,

Pe r for m t h e d ia g -
nosis according to
DTC.
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.
DATA, OPERATION, Subar u 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. ORY MODE, OPERATION, Subaru Select
Monitor.>
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. 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.

AUTOMATIC TRANSMISSION (DIAGNOSTICS)
7CHECK OUTPUT SIGNAL OF TCM.
1) Lift-up the vehicle and support with rigid
racks.
NOTE:Raise all wheels off floor.
2) Start the engine.
3) Shift the select lever to “D” range and
slowly increase vehicle speed to 20 km/h (12
MPH).
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. ORY MODE, OPERATION, Subaru Select
Monitor.>
4) Measure the voltage between TCM and
chassis ground.
Connector & terminal
(B55) No. 15 (+) — Chassis ground (–):
Is the voltage less than 1 V? Even if the SPORT
indicator light up,
the circuit has
returned to nor-
mal condition at
this time. A tempo-
rary poor contact
of connector or
harness may be
the cause. Repair
the harness or
connector in
reverse inhibitor
control circuit.
Go to step 8.
8CHECK POOR CONTACT.Is there poor contact in the
reverse inhibitor control circuit?
Repair the poor
contact.
Replace the TCM.

7CHECK INPUT SIGNAL FOR TCM USING
SUBARU SELECT MONITOR.
1) Connect all the connectors.
2) Lift-up the vehicle and support with rigid
racks.
NOTE:
Raise all wheels off floor.
3) Start the engine, and drive the vehicle.
4) Read the current data of front wheel speed
using Subaru Select Monitor. 5AT(diag)-15, OPERATION, 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. ORY MODE, OPERATION, Subaru Select
Monitor.>
Does the value of the front
wheel speed depending on the
acceleration and deceleration
of the vehicle?
Even if the SPORT
indicator light
blinks, the system
is in normal condi-
tion. A temporary
poor contact of
connector or har-
ness may be the
cause. Repair poor
contact of har-
ness in ATF tem-
perature sensor
and transmission
connector.
Replace the trans-
mission harness.
Step Check Yes No

6CHECK INPUT SIGNAL FOR TCM USING
SUBARU SELECT MONITOR.
1) Connect all the connectors.
2) Lift-up the vehicle and support with rigid
racks.
NOTE:
Raise all wheels off floor.
3) Start the engine, and set the vehicle in 1st
speed driving condition of manual mode.
4) Read the current data of torque converter

Basic Diagnostic Procedure
WIRING SYSTEM
•The wire color code, which consists of two letters
(or three letters including Br or Lg), indicates the
standard color (base color of the wire covering) by
its first letter and the stripe marking by its second
letter.
•The table lists the nominal sectional areas and
allowable currents of the wires.
CAUTION:
When replacing or repairing a wire, be sure to
use the same size and type of the wire which
was originally used.
NOTE:
•The allowable current in the table indicates the
tolerable amperage of each wire at an ambient
temperature of 40°C (104°F).
•The allowable current changes with ambient
temperature. Also, it changes if a bundle of more
than two wires is used.
•Each unit is either directly grounded to the body
or indirectly grounds through a harness ground ter-
minal. Different symbols are used in the wiring dia-
gram to identify the two grounding systems.
•The ground points shown in the wiring diagram
refer to the following:
NOTE:
All wiring harnesses are provided with a ground
point which should be securely connected.
