DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE OPERATION 1
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 2
With CONSULT
FLUID TEMP : 20В°C (68В°F) or more
With GST
NOTE:
When the ambient temperature is 20В°C (68В°F), the CVT fluid usually increases to 50 to 80В°C (122 to 176В°F) with driving in an urban area for approximately 10 minutes.
Is the CVT fluid 20В°C (68В°F) or more? YES >> GO TO 3.
NO >> 1. Warm the transaxle.
2. GO TO 3.
3.CHECK DTC DETECTION
Selector lever : “D” position
Accelerator pedal position : 1.0/8 or more
Vehicle speed : 40 km/h (25 MPH) or more
Is “P0744” detected? YES >> Go to TM-189, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK LINE PRESSURE
Perform line pressure test. Refer to TM-149, "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
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace the malfunction items.
Component Inspection
1.CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE
Check resistance between CVT unit connector terminal and ground.
Is the inspection
result normal?
YES >> INSPECTION END
NO >> There is a malfunction of torque converter clutch solenoid valve. Replace transaxle assembly.
Refer to TM-283, "Removal and Installation".
