1. 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.

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. Refer to CONTINUOUSLY VARIABLE TRANSMISSION (DIAGNOSTICS)>ACTIVE TEST .

   Does the indication change as 300 → 500 → 700 mA during forced operation, and does «Sec. Sol. Actual Current» synchronize with «Sec. 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 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. Refer to CONTINUOUSLY VARIABLE TRANSMISSION (TR690)>TRANSMISSION CONTROL MODULE (TCM) .

4. 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.

      Connector & terminal 

      (T4) No. 5 - Transmission body:

   Is the resistance approx. 5 - 7 Ω? (when cold)

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

   No:  Repair or replace the harness.
