DTC CONFIRMATION PROCEDURE

CAUTION:
Always drive vehicle at a safe speed.

NOTE:
Immediately after performing any "DTC CONFIRMATION PROCEDURE", always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION (PART 1)
With CONSULT-III
1. Turn ignition switch ON.
2. Select "Data Monitor" in "TRANSMISSION".
3. Check that output voltage of CVT fluid temperature sensor is within the range specified below.

ATF TEMP SEN : 0.16 - 2.03 V

Is the inspection result normal?
YES - Check intermittent incident. Intermittent Incident.
NO-1 ("ATF TEMP SEN" indicates 0.15 or less.)- P0710.
NO-2 ("ATF TEMP SEN" indicates 2.04 or more.)-GO TO 2.
2.CHECK DTC DETECTION (PART 2)
With CONSULT-III
1. Turn ignition switch ON.
2. Select "Data Monitor" in "TRANSMISSION".
3. Start engine and maintain the following conditions for at least 14 minutes.





With GST
Follow the procedure "With CONSULT-III".
Is "P0710" detected?
YES - Go to P0710.
NO - Check intermittent incident. Intermittent Incident.




Diagnosis Procedure
1.CHECK CVT FLUID TEMPERATURE SENSOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check resistance between TCM vehicle side harness connector terminals.





Is the inspection result normal?
YES - GO TO 5.
NO - GO TO 2.
2.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT TEMPERATURE SENSOR) (PART 1)
1. Disconnect CVT unit connector.
2. Check continuity between TCM vehicle side harness connector terminals and CVT unit vehicle side harness connector terminals.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace damaged parts.
3.CHECK HARNESS BETWEEN TCM AND CVT UNIT (CVT TEMPERATURE SENSOR) (PART 2)
Check continuity between TCM vehicle side harness connector terminals and ground.





Is the inspection result normal?
YES - GO TO 4.
NO - Repair or replace damaged parts.
4.CHECK CVT FLUID TEMPERATURE SENSOR
Check CVT fluid temperature sensor. P0710.
Is the inspection result normal?
YES - GO TO 6.
NO - GO TO 5.
5.CHECK DTC
With CONSULT-III
1. Turn ignition switch ON.
2. Perform "Self Diagnostic Results" in "TRANSMISSION".
Is only "P0710" detected?
YES - Replace control valve. Exploded View.
NO - Replace transaxle assembly. Exploded View (2WD), Exploded View (AWD).
6.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - Replace TCM. Exploded View.
NO - Repair or replace damaged parts.




Component Inspection (CVT Fluid Temperature Sensor)
1.CHECK CVT FLUID TEMPERATURE SENSOR
Check resistance between CVT unit harness connector terminals.





Is the inspection result normal?
YES - INSPECTION END
NO - Perform "Self Diagnostic Results" in "TRANSMISSION".
