DTC CONFIRMATION PROCEDURE

CAUTION:

• Be sure to perform “

TM-386, "Diagnosis Procedure"

” and then perform “DTC CONFIRMATION PRO-

CEDURE”.

• Never perform “DTC CONFIRMATION PROCEDURE” before the repairs. Doing so may result in a sec-

ondary malfunction.

• Be careful of the driving speed.

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.

2. Drive the vehicle.

3. Maintain the following conditions for 20 seconds or more.

4. Stop the vehicle.

5. Check the first trip DTC.
Is “P0965”detected?

Diagnosis Procedure

INFOID:0000000009268198

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  malfunctioning parts.

2.

CHECK PRIMARY PRESSURE SOLENOID VALVE

Check  primary pressure solenoid valve. Refer to 

TM-387, "Component Inspection (Primary Pressure Sole-

noid Valve)"

.

Is the inspection result normal?

YES 

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> Repair or replace  malfunctioning parts.

Component Inspection (Primary Pressure Solenoid Valve)

INFOID:0000000009268199
