DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE OPERATION (PART 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 (PART 2)
With CONSULT
FLUID TEMP : 10В°C (50В°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 10В°C (50В°F) or more? YES >> GO TO 3.
NO >> 1. Warm the transaxle.
2. GO TO 3.
3.CHECK DTC DETECTION
Selector lever : “D” position
Vehicle speed : 40 km/h (25 MPH) or more
Is “P0740” detected? YES >> Go to TM-185, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT
Is the check result
normal?
YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE
Check torque converter clutch solenoid valve. Refer to TM-185, "Component Inspection".
Is the check result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
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".
