1CHECK FUSE.
1) Turn the ignition switch to OFF.
2) Remove the MAIN SBF, SBF 8 and fuse
(No. 12), and then check those are not blown
out.
Is the fuse blown out? Replace the fuse.
If the replaced
fuse has blown out
easily, repair the
short circuit of har-
ness of each fuse.
Go to step 2.

Diagnostic Procedure with Diagnostic Trouble Code (DTC)
AUTOMATIC TRANSMISSION (DIAGNOSTICS)
Step Check Yes No
1CHECK HARNESS CONNECTOR BETWEEN
TCM AND TRANSMISSION.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from TCM and
transmission.
3) Measure the resistance of harness
between TCM connector and transmission
connector.
Connector & terminal
(B54) No. 16 — (B11) No. 7:
(B55) No. 18 — (B12) No. 5:
Is the resistance less than 1
Ω?
Go to step 2.Repair the open
circuit of harness
between TCM and
transmission con-
nector.
2CHECK HARNESS CONNECTOR BETWEEN
TCM AND TRANSMISSION.
Measure the resistance of harness between
TCM connector and chassis ground.
Connector & terminal
(B54) No. 16 — Chassis ground:
(B55) No. 18 — Chassis ground:
Is the resistance more than 1
MΩ?
Go to step 3.Repair the short
circuit of harness
between TCM and
chassis ground.
3CHECK TCM POWER SUPPLY OUTPUT.
1) Connect the connector to TCM. (Transmis-
sion connector is disconnected)
2) Turn the ignition switch to ON. (Engine
OFF)
3) Measure the voltage between TCM con-
nector and chassis ground.
Connector & terminal
(B54) No. 16 (+) — Chassis ground (–):
Is the voltage 10 — 13 V? Go to step 4.Go to step 5.
4CHECK TURBINE SPEED SENSOR INPUT
CIRCUIT OF TCM.
Measure the voltage between TCM connector
terminals.
Connector & terminal
(B55) No. 18 (+) — (B54) No. 19 (–):
Is the voltage 4 — 6 V? Go to step 6.Go to step 5.
5CHECK TCM I/O SIGNAL.
Check TCM I/O signal of power supply, ground
and PVIGN power supply relay. 5AT(diag)-11, ELECTRICAL SPECIFICA-
TION, Transmission Control Module (TCM) I/O
Signal.>
Is TCM I/O signal OK? Replace the TCM.
Tr a n s m i s s i o n C o n -
trol Module
(TCM).>
Repair the open or
short circuit for
power supply and
ground. Perform
the diagnosis
according to DTC
for PVIGN power
supply relay.
6CHECK HARNESS ASSEMBLY (TURBINE
SPEED SENSOR GROUND).
Check the installing condition of ground con-
necting harness (used for both of turbine
speed sensor 1, rear vehicle speed sensor).
Is the ground connecting har-
ness installed to transmission
body correctly, or the harness
and connector terminals not
damaged?
Go to step 7.When the poor
installation of
ground connect-
ing harness, install
it securely.
Replace the trans-
mission assembly
when the harness
is damaged. to 5AT-34, Auto-
matic Transmis-
sion Assembly.>

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
turbine speed 2 using Subaru Select Monitor.
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 turbine
speed sensor 2 change
depending on the acceleration,
deceleration and shifting gear
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 the
poor contact of
harness of turbine
speed sensor 2
and transmission
connector.
Go to step 7.
7CHECK HARNESS CONNECTOR BETWEEN
TRANSMISSION AND CONTROL VALVE
BODY.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from transmis-
sion.
3) Remove the transmission connector from
bracket.
4) Lift-up the vehicle and place it on rigid
racks.
NOTE:
Raise all wheels off floor.
5) Drain the ATF.
CAUTION:Do not drain ATF until it cools down.
6) Remove the oil pan, and disconnect the
connector from control valve body connector.
7) Measure the resistance between transmis-
sion connector and control valve body connec-
tor.
Connector & terminal
(T3) No. 6 — (T6) No. 3:
(T4) No. 7 — (T5) No. 15:
Is the resistance less than 1
Ω?
Go to step 8.Repair the open
circuit of harness
between transmis-
sion connector
and control valve
body connector.
8CHECK HARNESS CONNECTOR BETWEEN
TRANSMISSION AND CONTROL VALVE
BODY.
Measure the resistance between transmission
ground and control valve body connector.
Connector & terminal
(T6) No. 3 — Transmission ground:
(T5) No. 15 — Transmission ground:
Is the resistance more than 1
MΩ?
Replace the con-
trol valve body.
Control Valve
Body.>
Repair the short
circuit of harness
between transmis-
sion connector
and transmission
ground.
Step Check Yes No

D: ASSEMBLY
1) Clean all the parts before assembly.
2) Apply grease [Multemp AC-D, and SH-W or
equivalent] to each part. LECT LEVER, COMPONENT, General Descrip-
tion.>
3) Assemble in the reverse order of disassembly.
NOTE:
•Refer to “COMPONENT” for each tightening
torque. PONENT, General Description.>
•When pressing in the shift position pin, insert
from the left side of the vehicle.
•Affix the harness of the shift button switch and
the mode change switch at the marked positions.
•Connect the terminals of all switches to the re-
spective connectors.
4) After completing installation, shift the select le-
ver from the “P” range to the “D” range, then check
whether or not the selection indicator in the combi-
nation meter and the select lever position matches.
Also check whether the pointer and position mark
matches, and what the operating force is.
E: INSPECTION
1) Inspect the removed parts by comparing with
new ones for deformation, damage and wear. Re-
pair or replace if defective.
2) Confirm the select lever operating condition be-
fore assembly. Normal if it operates smoothly. CS-00641
