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 “P0962” detected?

YES

Diagnosis Procedure

INFOID:0000000009177605

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 ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace damaged parts.

2.

CHECK LINE PRESSURE SOLENOID VALVE CIRCUIT

Check continuity between CVT unit harness connector terminal and ground.

Is the inspection result normal?

YES >> Check

intermittent incident. Refer to

GI-49, "Intermittent Incident"

.

When all of the following conditions are satis-
fied and this state is maintained for 0.2 sec-
onds:
• TCM power supply voltage: More than 11 V
• TCM judges that solenoid valve circuit is

shorted to ground.

• Harness or connector

(Line pressure solenoid valve circuit is
shorted to ground)
