Diagnosis Procedure

INFOID:0000000012201179

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 CIRCUIT BETWEEN CVT UNIT AND GROUND

Check resistance between CVT unit harness connector terminal and ground.

Is the inspection result normal?

YES 

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> There is malfunction of torque converter clutch solenoid valve. Replace transaxle assembly. Refer

to 

TM-577, "Removal and Installation"

DTC CONFIRMATION PROCEDURE

CAUTION:

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.

PREPARATION BEFORE OPERATION

With CONSULT

1. Start the engine.

2. Select “Data Monitor” in “TRANSMISSION”.

3. Select “FLUID TEMP”.

4. Confirm that the CVT fluid temperature is in the following range. 

With GST

1. Start the engine.

2. Set the CVT fluid to 20

°

C (68

°

F) or more. 

NOTE:

When the ambient temperature is 20

°

C (68

°

F), the CVT fluid usually increases to 50 to 80

°

C (122 to

176

°

F) with driving in an urban area for approximately 10 minutes. 

Is the CVT fluid 20

°

C (68

°

F) or more? 

YES

>> GO TO 3.

NO

>> 1. Warm the transaxle. 

2. GO TO 3.

3.

CHECK DTC DETECTION

1. Drive the vehicle.

2. Maintain the following conditions for 30 seconds or more.

3. Stop the vehicle.

4. Check the first trip DTC.
Is “P0744” detected?
