P0963 PRESSURE CONTROL SOLENOID A

DTC Description

INFOID:0000000010622840

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connector (Line pressure solenoid valve circuit is open or shorted to power supply)
• Line pressure solenoid valve

FAIL-SAFE

• Selector shock is large
• Start  is  slow
• Acceleration is slow
• Lock-up is not performed
• Stop/start system prohibited
• Restart the engine during the stop/start system operation
• Turn OFF the electric oil pump relay

DTC CONFIRMATION PROCEDURE

1.

PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

1.

Start the engine and wait for 5 seconds or more.

2.

Check the first trip DTC.

Is “P0963” detected?

YES

>> Go to 

TM-618, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010622841

1.

CHECK CIRCUIT BETWEEN TCM AND CVT UNIT

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector and CVT unit connector.

3.

Check continuity between TCM harness connector terminal and CVT unit harness connector terminal. 

Is the inspection result normal?

YES 

>> GO TO 2.

NO

>> Repair or replace damaged parts.

2.

CHECK LINE PRESSURE SOLENOID VALVE CIRCUIT

- Start  is  slow
- Acceleration is slow
- Lock-up is not performed
- Stop/start system prohibited
- Restart the engine during the stop/start system operation
- Turn OFF the electric oil pump relay
• When a malfunction occurs on the high oil pressure side
- Selector shock is large
- Lock-up is not performed
- Stop/start system prohibited
