>> GO TO 2.
2.PREPARATION BEFORE OPERATION 2
With CONSULT-III
1. Start the engine.
2. Select “Data Monitor” in “TRANSMISSION”.
3. Select “FLUID TEMP”.
4. Confirm that the CVT fluid temperature is in the range below.
FLUID TEMP : 20°C (68°F) or more
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 40 seconds or more.

3. Stop the vehicle.
4. Check the first trip DTC.
Is “P0744” detected? YES >> Go to TM-421, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK LINE PRESSURE
Perform the line pressure test. Refer to TM-382, "Work Procedure".
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace the malfunction items.
2.CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE
1. Turn ignition switch OFF.
2. Disconnect the CVT unit connector.
3. Check the torque converter clutch solenoid valve. Refer to TM-421, "Component Inspection (Torque Converter Clutch Solenoid Valve)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
