DTC CONFIRMATION PROCEDURE


CAUTION:
Always drive vehicle at a safe speed.

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. CHECK DTC DETECTION

1.Set the vehicle to READY.
2.Drive the vehicle by motor.
3.Fully open the accelerator and accelerate the vehicle to 60 km/h (37 MPH).
4.Stop the vehicle.
5.Check DTC.
Is "P3241" detected?
YES- Go to .
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/face shield 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. CHECK CONNECTOR CONNECTION

1.Turn ignition switch OFF.
2.Check the connection condition of the traction motor inverter harness connector.
Is the inspection result normal?
YES- GO TO 2.
NO- Repair or replace damaged parts.

2. 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 3.

3. CHECK CONNECTION CONDITION

Check the connection condition of the 3-phase harness. Exploded View.
Is the inspection result normal?
YES- GO TO 4.
NO- Repair or replace damaged parts.

4. CHECK DISCONNECTION TRACTION MOTOR STATOR COIL

1.Disconnect the 3-phase harness from the traction motor inverter. Removal and Installation.
2.Check for an open circuit in the traction motor stator coil.





Is the inspection result normal?
YES- Replace the traction motor inverter. Removal and Installation.
NO- Replace the transmission assembly due to malfunction in the traction motor. Removal and Installation.
