DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK INPUT SIGNAL FOR TCM. After driving with warm up condition, park the vehicle while depressing the brake pedal at "N" range. Read the data of «Sec. Sol. Set Current» and «Sec. Sol. Actual Current» using Subaru Select Monitor.	Does the value of «Sec. Sol. Set Current» and «Sec. Sol. Actual Current» almost correspond?	Check for poor contact of connector.	Go to step 2 .
2 CHECK HARNESS. Turn the ignition switch to OFF. Disconnect the TCM and transmission connectors. Measure the resistance between TCM connector and chassis ground. Connector & terminal (B54) No. 12 - Chassis ground:	Is the resistance 1 MΩ or more?	Go to step 3 .	Repair the short circuit of harness.
3 CHECK SECONDARY SOLENOID. Measure the resistance between transmission connector and transmission body. Connector & terminal (T4) No. 6 - Transmission body:	Is the resistance approx. 7 Ω? (when engine cold)	Check for poor contact of the connector, and repair the defective part.	Go to step 4 .
4 CHECK HARNESS INSIDE TRANSMISSION. CAUTION: Start work after ATF cools down. Remove the transmission valve cover. Check for the harness pinch, damage.	Is the harness normal?	Go to step 5 .	Replace the transmission harness.
5 CHECK HARNESS INSIDE TRANSMISSION. Disconnect the control valve body connector. Measure the resistance between transmission connector and transmission body. Connector & terminal (T4) No. 6 - Transmission body:	Is the resistance 1 MΩ or more?	Replace the control valve body. Refer to CONTROL VALVE BODY .	Replace the transmission harness.
