DTC CONFIRMATION PROCEDURE


1. PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
- GO TO 2.

2. PERFORM DTC CONFIRMATION PROCEDURE-1

1.Turn ignition switch ON and wait at least 3 seconds.
2.Check DTC.
Is DTC detected?
YES- Proceed to P0A08.
NO- GO TO 3.

3. PERFORM DTC CONFIRMATION PROCEDURE-2

1.Set the vehicle to READY.
2.Drive the vehicle at more than 5 km/h (3.1 MPH).

CAUTION:
Always drive the vehicle at a safe speed.
3.Check DTC.
Is DTC detected?
YES- Proceed to P0A08.
NO- INSPECTION END


Diagnosis Procedure


WARNING:
- Because hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are handled incorrectly. Be sure to follow the correct work procedures when performing inspection and maintenance.
- Be sure to remove the service plug in order to shut off the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.
- Be sure to put the removed service plug in your pocket and carry it with you so that another person does not accidentally connect it while work is in progress.
- Be sure to wear insulating protective equipment consisting of glove, shoes and glasses before beginning work on the high voltage system.
- Clearly identify the persons responsible for high voltage work and ensure that other persons do not touch the vehicle. When not working, cover high voltage parts with an insulating cover sheet or similar item to prevent other persons from contacting them.
- High Voltage Precautions.

CAUTION:
There is the possibility of a malfunction occurring if the vehicle is changed to READY status while the service plug is removed. Therefore do not change the vehicle to READY status unless instructed to do so in the Service Manual.

1. PRECONDITIONING


WARNING:
Shut off high voltage circuit. How to Cut Off High Voltage.
Check voltage in high voltage circuit. (Check that condenser are discharged.)
1.Remove trunk finisher front. Trunk Room Trim.





2.Remove harness cover (1).









3.Measure voltage between high voltage harness terminals.









CAUTION:
For voltage measurements, use a tester which can measure to 500 V or higher.
- GO TO 2.

2. CHECK TRACTION MOTOR INVERTER AND HARNESS CONNECTOR INSTALLATION

Check traction motor inverter and harness connector installation. Exploded View.
Is the inspection result normal?
YES- GO TO 3.
NO- Repair traction motor inverter or harness connector installation.

3. CHECK INTER LOCK SWITCH SIGNAL

1.Turn ignition switch ON.
2.Check the voltage between HPCM harness connector and ground.





Is the inspection result normal?
YES- GO TO 5.
NO- GO TO 4.

4. CHECK INTER LOCK SWITCH SIGNAL CIRCUIT

1.Turn ignition switch OFF.
2.Disconnect HPCM harness connector.
3.Disconnect traction motor inverter harness connector.
4.Check the continuity between traction motor inverter harness connector and HPCM harness connector.





5.Also check harness connector for short to ground and to power.
Is the inspection result normal?
YES- Replace traction motor inverter. Removal and Installation.
NO- Repair or replace error-detected parts.

5. CHECK INTER LOCK SWITCH

1.Turn ignition switch OFF.
2.Check the continuity between traction motor inverter terminals.





3.Also check harness for short to ground.
Is the inspection result normal?
YES- Replace traction motor inverter. Removal and Installation.
NO- Repair or replace error-detected parts.
