1. CHECK DTC  .

   Read the DTC using Subaru Select Monitor. Ref. to TRANSMISSION (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .

   Besides DTC P0961, is DTC P0962 or P0963 displayed?

   Yes:  Perform the diagnosis according to DTCs other than P0961. Ref. to TRANSMISSION (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)>LIST .

   No:  Go to  2.

2. CHECK LINE PRESSURE SOLENOID (ACTIVE TEST)  .
   1. Turn the ignition switch to ON.
   2. Using the Subaru Select Monitor, perform the active test for line pressure solenoid. Ref. to TRANSMISSION (DIAGNOSTICS)>ACTIVE TEST .

   Is 300 → 500 → 700 mA indicated at the active test, and does [Lin. Sol. Actual Current] follow [Lin. Sol. Set Current]?

   Yes:  Go to  3.

   No:  Go to  4.

3. CHECK FOR POOR CONTACT  .

   Check for poor contact of harness and connector between TCM and line pressure 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 (TR690)>TRANSMISSION CONTROL MODULE (TCM) .

4. CHECK LINE PRESSURE SOLENOID  .
   1. Turn the ignition switch to OFF.
   2. Disconnect the transmission connector.
   3. Measure the resistance between transmission connector and transmission body.

      Connector & terminal 

      (T19) No. 11 - Transmission body:

   Is the resistance approximately 3.3 - 7.3 Ω? (When cold)

   Yes:  Replace the control valve body. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>CONTROL VALVE BODY .

   No:  Repair or replace the harness.
