CAUTION:

Use CHECK BOARD when measuring the TCM terminal voltage and resistance.
After servicing or replacing faulty parts, perform the last step of the basic diagnostic procedure. Ref. to TRANSMISSION (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE .

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.
CHECK SECONDARY SOLENOID (ACTIVE TEST).
1. Turn the ignition switch to ON.
2. Using the Subaru Select Monitor, perform the active test for secondary solenoid. Ref. to TRANSMISSION (DIAGNOSTICS)>ACTIVE TEST .
  Is 300 → 500 → 700 mA indicated at the active test, 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) .
CHECK SECONDARY SOLENOID.
1. Turn the ignition switch to OFF.
2. Disconnect the TCM connector.
3. Measure the resistance between TCM connector and transmission body.
Connector & terminal

(T10) No. 32 - Transmission body:

Is the resistance approximately 4.8 - 8.4 Ω? (When cold)

Yes: Replace the control valve body. Ref. to CONTINUOUSLY VARIABLE TRANSMISSION (TR580)>CONTROL VALVE BODY .

No: Repair or replace the harness.
