DTC CONFIRMATION PROCEDURE


CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If "DTC CONFIRMATION PROCEDURE" has been previously performed, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.

1. CHECK DTC DETECTION (PART 1)

With CONSULT
1.Turn ignition switch ON.
2.Select "DATA MONITOR".
3.Check that output voltage of CVT fluid temperature sensor is within the range specified below.





Is the inspection result normal?
YES- Check intermittent incident. Intermittent Incident.
NO-1 ("ATF TEMP SEN" indicates 0.15 or less.)-Refer to "Diagnosis Procedure".
NO-2 ("ATF TEMP SEN" indicates 2.04 or more.)-GO TO 2.

2. CHECK DTC DETECTION (PART 2)

With CONSULT
1.Turn ignition switch ON.
2.Select "DATA MONITOR".
3.Start engine and maintain the following conditions for at least 14 minutes.





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


Diagnosis Procedure


1. CHECK CVT FLUID TEMPERATURE SENSOR

1.Turn ignition switch OFF.
2.Disconnect CVT unit connector.
3.Check resistance between CVT unit connector terminals.





Is the inspection result normal?
YES- GO TO 2.
NO- GO TO 4.

2. CHECK CIRCUIT BETWEEN TCM AND CVT UNIT (CVT FLUID TEMPERATURE SENSOR) (PART 1)

1.Disconnect the TCM connector.
2.Check continuity between TCM harness connector terminals and CVT unit harness connector terminals.





Is the inspection result normal?
YES- GO TO 3.
NO- Repair or replace damaged parts.

3. CHECK CIRCUIT BETWEEN TCM AND CVT UNIT (CVT FLUID TEMPERATURE SENSOR) (PART 2)

Check continuity between TCM harness connector terminals and ground.





Is the inspection result normal?
YES- Check intermittent incident. Intermittent Incident.
NO- Repair or replace damaged parts.

4. CHECK TERMINAL CORD ASSEMBLY (PART 1)

1.Remove terminal cord assembly. Exploded View.
2.Check continuity between CVT unit harness connector terminals and control valve harness connector terminals.





Is the inspection result normal?
YES- GO TO 5.
NO- Repair or replace damaged parts.

5. CHECK TERMINAL CORD ASSEMBLY (PART 2)

Check terminal cord assembly harness cladding for damage.
Is the inspection result normal?
YES- GO TO 6.
NO- Repair or replace damaged parts.

6. CHECK DTC (TCM)

With CONSULT
1.Perform DTC CONFIRMATION PROCEDURE. Refer to "DTC Logic".
2.Perform "SELF-DIAG RESULTS" mode for "TRANSMISSION".
Is only "P0710" detected?
YES-1 ("P0710" only)-There is a malfunction of the CVT fluid temperature sensor. Replace the control valve. Removal And Installation.
YES-2 ("P0710" and other DTC)-Replace the transaxle assembly. Removal And Installation.
NO- Check intermittent incident. Intermittent Incident.
