DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
Step
3 CHECK 2-4 BRAKE DUTY SOLENOID.
Measure resistance between transmission
connector receptacle's terminals.
Terminal
(T4) No. 16 — No. 9:
Is the measured value within the specified
range?
4 PREPARE SUBARU SELECT MONITOR.
Do you have a Subaru Select Monitor?
5 CHECK OUTPUT SIGNAL EMITTED FROM
TCM.
1) Connect all connectors.
2) Start the engine and warm-up the transmis-
sion until ATF temperature is above 80°C
(176°F).
NOTE:
If ambient temperature is below 0°C (32°F),
drive the vehicle until the ATF reaches its oper-
ating temperature.
3) Turn ignition switch to ON (engine OFF).
4) Move select lever to "N".
5) Throttle is fully closed.
6) Measure voltage between TCM connector
and chassis ground.
Connector & terminal
(B54) No. 18 (+) — Chassis ground ( − − − − ):
