Subaru Crosstrek Service Manual: Dtc p0966 pressure control solenoid "b" control circuit low

DTC detecting condition:

Immediately at fault recognition

Trouble symptom:

Excessive shift shock

CAUTION:

Use the check board when measuring the TCM terminal voltage and resistance.

1.CHECK INPUT SIGNAL FOR TCM.

1) After driving with warm up condition, park the vehicle while depressing the brake pedal at “D” range.

2) Read the data of «Commanded Forward & Reverse Linear Solenoid Current» and «Actual Forward & Reverse Linear Solenoid Current» using Subaru Select Monitor.

Does the value of «Commanded Forward & Reverse Linear Solenoid Current» and «Actual Forward & Reverse Linear Solenoid Current» almost correspond?

Check for poor contact of connector.

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0966 PRESSURE CONTROL SOLENOID "B" CONTROL CIRCUIT LOW">Go to Step 2.

2.CHECK HARNESS.

1) Turn the ignition switch to OFF.

2) Disconnect the TCM connector.

3) Disconnect the transmission connector.

4) Measure the resistance between TCM connector and chassis ground.

Connector & terminal

(B54) No. 16 — Chassis ground:

Is the resistance 1 M? or more?

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0966 PRESSURE CONTROL SOLENOID "B" CONTROL CIRCUIT LOW">Go to Step 3.

Repair the short circuit of harness.

3.CHECK F&R SOLENOID.

Measure the resistance between transmission connector and transmission body.

Connector & terminal

(T4) No. 7 — Transmission body:

Is the resistance approx. 4 — 6 ?? (when cold)

Check for poor contact of connector, and if no fault is found, replace the TCM. Transmission Control Module (TCM)">

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0966 PRESSURE CONTROL SOLENOID "B" CONTROL CIRCUIT LOW">Go to Step 4.

4.CHECK HARNESS INSIDE TRANSMISSION.

CAUTION:

Start work after ATF cools down.

1) Remove the transmission valve cover.

2) Check for the harness pinch, damage.

Is there any fault in the harness?

Replace the transmission harness.

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P0966 PRESSURE CONTROL SOLENOID "B" CONTROL CIRCUIT LOW">Go to Step 5.

5.CHECK HARNESS INSIDE TRANSMISSION.

1) Disconnect the control valve body connector.

2) Measure the resistance between transmission connector and transmission body.

Connector & terminal

(T4) No. 7 — Transmission body:

Is the resistance 1 M? or more?

Replace the control valve body. Control Valve Body">

Replace the transmission harness.

• Detect the short circuit to ground in transmission forward/reverse clutch pressure solenoid circuit.

• Judge as NG when an abnormal signal is received from the solenoid driver IC of the transmission forward/reverse clutch pressure solenoid drive circuit.
