With CONSULT
1.Perform normal charging until charging is completed.
2.Turn power switch ON.
3.Check "SELF-DIAG RESULTS" of "CHARGER".
Is DTC detected?
YES- Proceed to "TYPE C AND D : Diagnosis Procedure" .
NO- INSPECTION END
TYPE A AND B : 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.
- Erase DTC after the work is completed.
1. CHECK SELF-DIAGNOSTIC RESULT IN VCM
With CONSULT
1.Turn power switch ON.
2.Check "SELF-DIAG RESULTS" of "EV/HEV".
Is any DTC is detected?
YES- Check the DTC.
NO- GO TO 2.
2. PERFORM DTC CONFIRMATION PROCEDURE AGAIN-I
With CONSULT
1.Erase self-diagnostic result.
2.Turn power switch OFF.
3.Perform DTC confirmation procedure again by using an EVSE other than the one is used for the previous
DTC confirmation procedure. Refer to "DTC Logic" .
Is the DTC detected again?
YES- GO TO 3.
NO- Replace EVSE.
3. PRECONDITIONING
WARNING:
Disconnect high voltage. Refer to "How to Disconnect High Voltage" Service and Repair.
Check 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 "Removal and Installation" Service and Repair (without Li-ion battery heater models), "Removal and Installation" Service and Repair (with Li-ion battery heater models).
2.Disconnect high voltage harness connector from front side of Li-ion battery. Refer to "Removal and Installation" Service and Repair (without Li-ion battery heater models), "Removal and Installation" Service and Repair (with Li-ion battery heater models).
3.Measure voltage between high voltage harness connector 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 HIGH VOLTAGE HARNESS
1.Disconnect normal charge port harness connector and on-board charger harness connector.
2.Check the voltage between normal charge port harness connector and on-board charger harness connector.
3.Also check harness for short to ground and check for short circuit between wires.
Is the inspection result normal?
YES- GO TO 5.
NO- Repair or replace error-detected parts.
5. PERFORM DTC CONFIRMATION PROCEDURE AGAIN-II
With CONSULT
1.Reconnect all harness connectors disconnected.
2.Turn power switch ON.
3.Erase self-diagnostic result.
4.Turn power switch OFF.
5.Perform DTC confirmation procedure. Refer to "DTC Logic" .
Is DTC "B29C1" detected?
YES- Replace on-board charger (fuse is fusing). Refer to "Removal and Installation" Removal And Installation.
NO- INSPECTION END
TYPE C AND D : Diagnosis Procedure
1. CHECK EVSE SPECIFICATIONS
Check whether or not the EVSE conforms to the SAE-J1772 standard.
Is the correct EVSE being used?
YES- GO TO 2.
NO- Explain to the customer that the correct EVSE must be used.
2. PERFORM DTC CONFIRMATION PROCEDURE AGAIN
With CONSULT
1.Turn power switch ON.
2.Erase self-diagnostic result.
3.Turn power switch OFF.
4.Perform DTC confirmation procedure again by using a EVSE other than the one is used for the previous
DTC confirmation procedure. Refer to "DTC Logic" .
Is the DTC detected again?
YES- GO TO 3.
NO- Replace EVSE.
3. CHECK INTERMITTENT INCIDENT
Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
Is the inspection result normal?
YES- Replace on-board charger. Refer to "Removal and Installation" Removal And Installation.
NO- Repair or replace error-detected parts.
