Subaru Crosstrek Service Manual: Dtc p2763 torque converter clutch pressure control solenoid control circuit high

DTC detecting condition:

Immediately at fault recognition

Trouble symptom:

• No lock-up occurs.

• Engine stalls.

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

1.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 transmission connectors.

Connector & terminal

(B54) No. 15 — (B11) No. 11:

Is the resistance less than 1 ??

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2763 TORQUE CONVERTER CLUTCH PRESSURE CONTROL SOLENOID CONTROL CIRCUIT HIGH">Go to Step 2.

Repair the open circuit of harness.

2.CHECK HARNESS.

1) Turn the ignition switch to ON.

2) Measure the voltage between TCM connector and chassis ground.

Connector & terminal

(B54) No. 15 (+) — Chassis ground (−):

Is the voltage approx. 0 V?

Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2763 TORQUE CONVERTER CLUTCH PRESSURE CONTROL SOLENOID CONTROL CIRCUIT HIGH">Go to Step 3.

Repair the short circuit of harness.

3.CHECK LOCK-UP DUTY SOLENOID.

Measure the resistance between transmission connector and transmission body.

Connector & terminal

(T4) No. 11 — Transmission body:

Is the resistance approx. 10 — 13.5 ?? (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 P2763 TORQUE CONVERTER CLUTCH PRESSURE CONTROL SOLENOID CONTROL CIRCUIT HIGH">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 P2763 TORQUE CONVERTER CLUTCH PRESSURE CONTROL SOLENOID CONTROL CIRCUIT HIGH">Go to Step 5.

5.CHECK HARNESS INSIDE TRANSMISSION.

1) Disconnect the control valve body connector.

2) Turn the ignition switch to ON.

3) Measure the voltage between transmission connector and transmission body.

Connector & terminal

(T4) No. 11 (+) — Transmission body (−):

Is the voltage approx. 0 V?

Replace the control valve body. Control Valve Body">

Replace the transmission harness.

• Detect short circuit to power supply or open circuit of the lock-up clutch pressure control solenoid drive circuit.

• Judge as NG when an abnormal signal is received from the solenoid driver IC of the lock-up clutch pressure control solenoid drive circuit.
