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-III
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.

ATF TEMP SEN : 0.16 - 2.03 V

Is the inspection result normal?
YES - Check intermittent incident. Refer to Intermittent Incident.
NO-1 ("ATF TEMP SEN" indicates 0.15 or less.)-Refer to CVT RE0F09B.
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".
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 CVT RE0F09B.
NO - Check intermittent incident. Refer to Intermittent Incident.




Diagnosis Procedure
1.CHECK CVT FLUID TEMPERATURE SENSOR CIRCUIT





1. Turn ignition switch OFF.
2. Disconnect TCM harness connector.
3. Check resistance between TCM harness connector F16 terminal
13 and 25.





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 harness connector.
2. Check continuity between TCM harness connector F16 (A) terminal 13, 25 and CVT unit harness connector F46 (B) terminal
17, 19.





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 harness connector F16 terminal 13, 25 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. Refer to CVT RE0F09B.
Is the inspection result normal?
YES - GO TO 5.
NO - Replace transaxle assembly. Refer to Exploded View.
5.DETECT MALFUNCTIONING ITEMS
Check TCM connector pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - Replace TCM. Refer to 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 terminal 17 and 19.





Is the inspection result normal?
YES - INSPECTION END
NO - Replace transaxle assembly. Refer to Exploded View.
