1. CHECK DTC. 

   Read the DTC using Subaru Select Monitor.

   Besides DTC P0965, is any of the DTCs P0717, P0720, P0966, P0967, P2747 and P2751 displayed?

   • Yes  : Perform the diagnosis according to DTCs other than P0965.
   • No  : Go to 2. 
2. CHECK F&R SOLENOID (ACTIVE TEST). 
   1. Turn the ignition switch to ON.
   2. Using the Subaru Select Monitor, perform forced operation of the F&R solenoid. Ref. to TRANSMISSION (DIAGNOSTICS)>Active Test .

   Is 300 → 500 → 700 mA indicated at forced operation, and does [Actual Forward & Reverse Linear Solenoid Current] follow [Commanded Forward & Reverse Linear Solenoid 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 F&R 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) .
4. CHECK F&R SOLENOID. 
   1. Turn the ignition switch to OFF.
   2. Disconnect the transmission connector.
   3. Measure the resistance between transmission connector and transmission body.

      Turbo model 

      (T4) No. 9 - Transmission body:

   Is the resistance approximately 4 - 6 Ω? (when cold)

   • Yes  : Replace the control valve body. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION(TR580)>Control Valve Body . Ref. to CONTINUOUSLY VARIABLE TRANSMISSION(TR690)>Control Valve Body .
   • No  : Repair or replace the harness.
