Diagnosis ProcedureINFOID:0000000009464062
1.CHECK CIRCUIT BETWEE N 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-43, "Intermittent Incident".
NO >> GO TO 3.
3.CHECK CIRCUIT BETW EEN CVT UNIT AND CONTROL VALVE
1. Disconnect control valve connector. Refer to TM-186, "Exploded View"
.
2. Check continuity between CVT unit harness connecto r terminal and control valve harness connector ter-
minal.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace terminal code assembly. Refer to TM-186, "Exploded View"
.
4.CHECK CIRCUIT BETWEEN CONTROL VALVE AND GROUND
Check resistance between control valve harness connector terminal and ground.
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-43, "Intermittent Incident".
NO >> There is malfunction of torque converter clutch solenoid valve. Replace transaxle assembly. Refer
to TM-206, "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 temper ature 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 10 seconds or more.
3. Stop the vehicle.
4. Check the first trip DTC.
Is
“P0744” detected?
YES >> Go to TM-125, "Diagnosis Procedure".
