1. Basic Diagnostic Procedure
A: PROCEDURE
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using the interview checklist.

2) Before performing diagnosis, inspect the
following item which might influence the AT
problems.
•General inspection INSPECTION, General Description.>
•Oil leakage
•Stall speed test
•Line pressure test Pressure Test.>
•Transfer Clutch Pressure Test 33, Transfer Clutch Pressure Test.>
•Time Lag Test Te s t . >
•Road Test
•Inhibitor Switch Switch.>
Is the unit that might influence
the AT problem normal?
Go to step 2.Repair or replace
each item.
2CHECK SPORT INDICATOR LIGHT.
After the ignition switch is turned to ON, wait
for at least 2 seconds.
Does the SPORT indicator
light illuminate?
Go to step 4.Go to step 3.
3CHECK SPORT INDICATOR LIGHT.
1) Turn the ignition switch to OFF.
2) Check the SPORT indicator light. 5AT(diag)-23, INSPECTION, SPORT Indicator
Light Display.>
3) After the ignition switch is turned to ON,
wait for at least 2 seconds.
Does the SPORT indicator
light blink?
Go to step 4.Go to step 5.
4CHECK DTC.
Read the DTC. TION, Read Diagnostic Trouble Code (DTC).>
NOTE:If the communication function of Subaru Select
Monitor cannot be executed normally, check
communication circuit. COMMUNICATION FOR INITIALIZING IM-
POSSIBLE, Diagnostic Procedure for Subaru
Select Monitor Communication.>
Is DTC displayed? Go to step 6.
NOTE:
Record all DTCs.
Go to step 5.
5PERFORM GENERAL DIAGNOSTICS.
1) Inspect using “Diagnostic Procedure with-
out Diagnostic Trouble Code (DTC)”. 5AT(diag)-120, Diagnostic Procedure without
Diagnostic Trouble Code (DTC).>
2) Perform the clear memory mode.
3) Perform the inspection mode. 5AT(diag)-19, Inspection Mode.>
4) Display DTC.
Is DTC displayed? Go to step 6.Inspect using

sion connector and control valve body connec-
tor.
Connector & terminal
(B11) No. 7 — (T5) No. 15:
(B11) No. 1 — (T5) No. 14:
Is the resistance less than 1
Ω?
Go to step 8.Repair the open
circuit of harness
between control
valve body con-
nector and trans-
mission connector.
8CHECK HARNESS CONNECTOR BETWEEN
TRANSMISSION AND CONTROL VALVE
BODY.
Measure the resistance between transmission
ground and control valve body connector.
Connector & terminal
(T5) No. 15 — Transmission ground:
(T5) No. 14 — Transmission ground:
Is the resistance more than 1
MΩ?
Go to step 9.Repair the short
circuit of harness
between transmis-
sion connector
and transmission
ground.
Step Check Yes No
