DTC CONFIRMATION PROCEDURE

CAUTION:

• Be sure to perform “

TM-205, "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?

YES

TM-205, "Diagnosis Procedure"

.

NO

Diagnosis Procedure

INFOID:0000000009759449

1.

CHECK INTERMITTENT INCIDENT

Refer to 

GI-39, "Intermittent Incident"

.

Is the inspection result normal?

YES 

>> Replace transaxle assembly. Refer to 

TM-283, "Removal and Installation"

.

NO

>> Repair or replace malfunctioning parts.

Diagnosis Procedure

INFOID:0000000009759451

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-206, "Component Inspection"

.

Is the inspection result normal?

YES >> Check 

intermittent incident. Refer to 

GI-39, "Intermittent Incident"

.

NO

>> Repair or replace malfunctioning parts.

Component Inspection

INFOID:0000000009759452

1.

CHECK PRIMARY PRESSURE SOLENOID VALVE

Check resistance between CVT unit connector terminal and ground.
