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 60 km/h (37 MPH).
3.Stop the vehicle.
4.Check DTC.
Is "P3240" 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. CHECK DTC HIGH VOLTAGE SYSTEMS
1.Power switch ON and wait 10 seconds or more.
2.Check DTC of the high voltage systems.
Were there any detected DTC related to a high voltage systems other than the traction motor inverter?
YES- Check DTC detected item.
NO- GO TO 2.
2. CHECK TRACTION MOTOR RESOLVER OFFSET DATA
1.Use CONSULT to read the traction motor resolver offset, and record the result.
NOTE:
"Work support" - "RESOLVER WRITE" can be used to check the traction motor resolver offset that is currently stored by the traction motor inverter.
2.Remove the under cover and record the traction motor resolver offset that is stamped on the traction motor.
NOTE:
For the location of traction motor resolver offset stamping, refer to "Description" Description.
3.Check whether or not the value read with CONSULT matches the value which was stamped on the traction motor.
Do the values match?
YES- GO TO 3.
NO- Write the traction motor resolver offset to the traction motor inverter. Refer to "Work Procedure" Work Procedure.
3. 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 4.
4. 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-harness connection conditions. Refer to "Exploded View"
Is the inspection result normal?
YES- GO TO 5.
NO- Tighten the 3-phase harness to the specified torque. Refer to "Exploded View".
5. 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- GO TO 6.
NO- Remove the traction motor. Refer to "Removal and Installation" Removal And Installation.
6. CHECK TRACTION MOTOR INVERTER HIGH VOLTAGE HARNESS CONNECTOR
Check the connection conditions of the traction motor inverter high voltage harness connector.
Is the inspection result normal?
YES- GO TO 7.
NO- Repair or replace damaged parts.
7. CHECK HIGH VOLTAGE HARNESS
Check the following items. Refer to "TRACTION MOTOR INVERTER : Circuit Diagram" Circuit Diagram.
- Check for an open circuit or short circuit between DC/DC-J/B and Li-ion battery.
- Check for an open circuit or short circuit between DC/DC-J/B and A/C inverter compressor.
- Check for an open circuit or short circuit between DC/DC-J/B and PTC element heater.
- Check for an open circuit or short circuit between DC/DC-J/B and on board charger.
- Check for an open circuit or short circuit between DC/DC-J/B and quick charge port.
Is the inspection result normal?
YES- Replace the traction motor inverter. Refer to "Removal and Installation".
NO- Repair or replace damaged parts.
