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

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

VEHICLE SPEED : 10 km/h (6 MPH) or more
ACC PEDAL OPEN : More than 1.0/8
RANGE : "D" position
ENG SPEED : 450 rpm or more
Driving location : Driving the vehicle uphill (increased engine load) will help maintain the driving conditions required for this test.

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


Diagnosis Procedure


1. CHECK PRIMARY SPEED SENSOR

With CONSULT
1.Start engine.
2.Check voltage between TCM connector terminals.





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 connector.
3.Turn ignition switch ON.
4.Check voltage between primary speed sensor vehicle side harness connector terminals.





5.Check voltage between primary speed sensor vehicle side harness connector terminal 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)

1.Turn ignition switch OFF.
2.Disconnect TCM connector and CVT unit connector.
3.Check continuity between TCM vehicle side harness connector terminal and ground.





Is the inspection result normal?
YES- GO TO 4.
NO- Repair or replace damaged parts.

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

Check continuity between TCM vehicle side harness connector terminal and primary speed sensor vehicle side harness connector terminal.





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

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

Check continuity between TCM vehicle side harness connector terminal 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.
3.Check continuity between IPDM E/R vehicle side harness connector terminal and primary speed sensor vehicle side harness connector terminal.





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 vehicle side harness connector terminal 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. 58, 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 and CVT unit connector.
3.Check continuity between TCM vehicle side harness connector terminal and primary speed sensor vehicle side harness connector terminal.





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)

Check continuity between TCM vehicle side harness connector terminal 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 connector terminal and ground.





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

11. CHECK TCM

1.Replace with the same type of TCM. Exploded View.
2.Connect each connector.
3.Perform "DTC CONFIRMATION PROCEDURE". .
Is "P0715" detected?
YES- Replace primary speed sensor. Exploded View.
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.
