DTC CONFIRMATION PROCEDURE


CAUTION:
Always drive vehicle at a safe speed.

1. PRECONDITIONING

If "DTC CONFIRMATION PROCEDURE" has been previously conducted, always power switch OFF and wait at least 10 seconds before conducting the next test.
- GO TO 2.

2. CHECK DTC DETECTION

With CONSULT
1.Set the vehicle to READY and wait for 10 seconds or more.
2.Fully open the accelerator and accelerate the vehicle to 10 km/h (6 MPH).
3.Stop the vehicle.
4.Check DTC.
Is "P3241" detected?
YES- Go to "Diagnosis Procedure" .
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 disconnect the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.
- To prevent the removed service plug from being connected by mistake during the procedure, always carry it in your pocket or put it in the tool box.
- Be sure to wear insulating protective equipment consisting of glove, shoes, face shield 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.
- Refer to "High Voltage Precautions" 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:
Disconnect high voltage circuit. Refer to "How to Disconnect High Voltage" Service and Repair.
Check the voltage in high voltage circuit. (Check that condenser are discharged.)
1.Lift up the vehicle and remove the li-ion battery under covers. Refer to "Exploded View" Service and Repair.
2.Disconnect the high voltage connector from front side of Li-ion battery. Refer to "Removal and Installation" Service and Repair.





3.Measure voltage between high voltage harness terminals.
DANGER:


Touching high voltage components without using the appropriate protective equipment will cause electrocution.
Standard: 5 V or less

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

2. CHECK THE CONNECTION CONDITIONS OF THE TRACTION MOTOR INVERTER U-V-W TERMINALS

Remove the high voltage safety cover and 3-phase harness cover from the traction motor inverter, and check the 3-phase harness connection conditions. Refer to "Exploded View"
Is the inspection result normal?
YES- GO TO 3.
NO- Tighten the 3-phase harness to the specified torque. Refer to "Exploded View

3. CHECK DISCONNECTION TRACTION MOTOR STATOR COIL

1.Disconnect the 3-phase harness from the traction motor inverter. Refer to "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. Refer to "Removal and Installation"
NO- Remove the traction motor. Refer to "Removal and Installation" Removal And Installation.
