DTC CONFIRMATION PROCEDURE


CAUTION:
Be careful of the driving speed.

1. PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
- GO TO 2.

2. CHECK DTC DETECTION

1.Start the engine.
2.Drive the vehicle.
3.Maintain the following conditions for 10 seconds or more.





4.Stop the vehicle.
5.Check the first trip DTC.
Is "P0715" detected?
YES- Go to .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK PRIMARY SPEED SENSOR POWER CIRCUIT

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





Is the inspection result normal?
YES - GO TO 2.
NO- GO TO 6.

2. CHECK PRIMARY SPEED SENSOR GROUND CIRCUIT

Check continuity between primary speed sensor harness connector terminal and ground.





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

3. CHECK CIRCUIT BETWEEN PRIMARY SPEED SENSOR AND TCM (PART 1)

1.Turn ignition switch OFF.
2.Disconnect TCM connector.
3.Check continuity between primary speed sensor harness connector terminal and TCM harness connector terminal.





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

4. CHECK CIRCUIT BETWEEN PRIMARY SPEED SENSOR AND TCM (PART 2)

Check continuity between primary speed sensor harness connector terminal and ground.





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

5. CHECK TCM INPUT SIGNALS

1.Connect all of disconnected connectors.
2.Lift the vehicle.
3.Start the engine.
4.Check frequency of primary speed sensor.





Is the inspection result normal?
YES - Check intermittent incident. Intermittent Incident.
NO- Replace primary speed sensor. Removal And Installation.

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

1.Disconnect IPDM E/R connector.
2.Check continuity between IPDM E/R harness connector terminal and primary speed sensor harness connector terminal.





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

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

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





Is the check result normal?
YES- GO TO 8.
NO- Repair or replace malfunctioning parts.

8. DETECT MALFUNCTIONING ITEMS

Check the following items:
- Harness open circuit or short circuit between ignition switch and IPDM E/R. Ignition Power Supply.
- 10A fuse (No.49, IPDM E/R). IPDM E/R Terminal Arrangement.
- IPDM E/R
Is the check result normal?
YES- Check intermittent incident. Intermittent Incident.
NO- Repair or replace malfunctioning parts.
