CHECK DTC.
Read the DTC using Subaru Select Monitor.

Besides DTC P0961, is DTC P0962 or P0963 displayed?
- Yes : Perform the diagnosis according to DTCs other than P0961.
- No : Go to 2.
CHECK SECONDARY SOLENOID (ACTIVE TEST).
1. Turn the ignition switch to ON.
2. Using the Subaru Select Monitor, perform forced operation of the secondary solenoid. Ref. to TRANSMISSION (DIAGNOSTICS)>Active Test .
Is 300 → 500 → 700 mA indicated at forced operation, and does [Secondary Actual Current] follow [Secondary Set Current]?
- Yes : Go to 3.
- No : Go to 4.
CHECK FOR POOR CONTACT.
Check for poor contact of harness and connector between TCM and secondary solenoid.

Is there poor contact?
- Yes : Repair the poor contact of harness and connector.
- No : Recheck the poor contact of harness and connector. Replace the TCM if no fault is found. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION(TR580)>Transmission Control Module (TCM) . Ref. to CONTINUOUSLY VARIABLE TRANSMISSION(TR690)>Transmission Control Module (TCM) .
CHECK SECONDARY SOLENOID.
1. Turn the ignition switch to OFF.
2. Disconnect the transmission connector.
3. Measure the resistance between transmission connector and transmission body.
