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

With CONSULT
1.Turn ignition switch ON.
2.Select "DATA MONITOR".
3.Start engine and maintain the following conditions for at least 5 consecutive seconds.





With GST
Follow the procedure "With CONSULT".
Is "P0715" detected?
YES- Go to "Diagnosis Procedure".
NO- Check intermittent incident. Intermittent Incident.


Diagnosis Procedure


1. CHECK PRIMARY SPEED SENSOR

With CONSULT





1.Start engine.
2.Check voltage between TCM harness connector F16 terminal
25, 46 and 25, 48.










3.If OK, check pulse when vehicle cruises.





Is the inspection result normal?

YES- GO TO 12.
NO- GO TO 2.

2. CHECK POWER AND SENSOR GROUND






1.Turn ignition switch OFF.
2.Disconnect primary speed sensor harness connector.
3.Turn ignition switch ON.
4.Check voltage between primary speed sensor harness connector F8 terminal 1 and 3.










5.Check voltage between primary speed sensor harness connector F8 terminal 3 and ground.





Is the inspection result normal?
YES- GO TO 3.
NO-1- Battery voltage is not supplied between terminals 1 and
3, terminal 3 and ground: GO TO 6.
NO-2- Battery voltage is not supplied between terminals 1 and 3 only: GO TO 8.

3. CHECK HARNESS BETWEEN TCM AND PRIMARY SPEED SENSOR (SENSOR GROUND)

NO- Repair or replace damaged parts.

5. CHECK HARNESS BETWEEN TCM AND PRIMARY SPEED SENSOR (PART 2)






Check continuity between TCM harness connector F16 terminal 33 and ground.





Is the inspection result normal?
YES- GO TO 10.
NO- Repair or replace damaged parts.

6. CHECK HARNESS BETWEEN IPDM E/R AND PRIMARY SPEED SENSOR (POWER) (PART 1)






1.Turn ignition switch OFF.
2.Disconnect IPDM E/R connector F10.
3.Check continuity between IPDM E/R harness connector F10 terminal 58 and primary speed sensor harness connector F8 terminal 3.





Is the inspection result normal?
YES- GO TO 7.
NO- Repair or replace damaged parts.

7. CHECK HARNESS BETWEEN IPDM E/R AND PRIMARY SPEED SENSOR (POWER) (PART 2)






Check continuity between IPDM E/R harness connector F10 terminal 58 and ground.





Is the inspection result normal?
YES-Check the following.
- Harness for short or open between ignition switch and
IPDM E/R
- 10A fuse (No. 34, located in IPDM E/R)
- Ignition switch
NO- Repair or replace damaged parts.

8. CHECK HARNESS BETWEEN TCM AND PRIMARY SPEED SENSOR (SENSOR GROUND) (PART 1)






1.Turn ignition switch OFF.
2.Disconnect TCM connector.
3.Check continuity between TCM harness connector F16 terminal
25 (A) and primary speed sensor harness connector F8 (B) terminal 1.





Is the inspection result normal?

YES- GO TO 9.
NO- Repair or replace damaged parts.

9. CHECK HARNESS BETWEEN TCM AND PRIMARY SPEED SENSOR (SENSOR GROUND) (PART 2)






1.Disconnect CVT unit harness connector.
2.Check continuity between TCM harness connector F16 terminal
25 and ground.





Is the inspection result normal?
YES- GO TO 10.
NO- Repair or replace damaged parts.

10. CHECK CVT UNIT CIRCUIT






Check continuity between CVT unit harness connector F46 terminal
19 and ground.





Is the inspection result normal?
YES- GO TO 11.
NO- Repair or replace damaged parts.

11. CHECK TCM

1.Replace same type TCM. Exploded View.
2.Connect each connector.
3.Perform "DTC CONFIRMATION PROCEDURE". Refer to "DTC Logic".
Is "P0715" detected?
YES- Replace primary speed sensor. Removal And Installation.
NO- Replace TCM. Exploded View.

12. 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.
