1.CHECK DTC.
Read the DTC using Subaru Select Monitor.
Besides DTC P0961, is DTC P0962 or P0963 displayed?
Perform the diagnosis according to DTCs other than P0961.
Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0961 PRESSURE CONTROL SOLENOID "A" CONTROL CIRCUIT RANGE/PERFORMANCE">Go to Step 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. 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»?

3.CHECK FOR POOR CONTACT.
Check for poor contact of harness and connector between TCM and secondary solenoid.
Is there poor contact?
Repair the poor contact of harness and connector.
Recheck the poor contact of harness and connector. Replace the TCM if no fault is found. 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. 6 — Transmission body:
Is the resistance approx. 5 — 7 ?? (when cold)
Replace the control valve body. Control Valve Body">
Repair or replace the harness.
1. OUTLINE OF DIAGNOSIS
• Detect the malfunction of transmission line pressure solenoid drive circuit.
• Judge as NG when the deviation between target current and actual current of the transmission line pressure solenoid becomes equal to or larger than the predetermined value.
2. EXECUTION CONDITION
Secondary Parameters | Execution condition |
12 V battery system voltage | ≥ 9 V |
3. DIAGNOSTIC METHOD
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Malfunction Criteria | Threshold Value |
ABS (Target line pressure control solenoid valve current − Measured line pressure control solenoid valve current) | > 0.2 A |
Time Needed for Diagnosis: 5 seconds
Malfunction Indicator Light Illumination: Illuminates as soon as a malfunction occurs.
