Component Inspection (Quick Charge Port)
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. 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 2.
2. CHECK QUICK CHARGE PORT
1.Turn power switch OFF.
2.Remove quick charge port. Refer to "Removal and Installation" Removal and Installation.
3.Check the continuity between quick charge port terminal and quick charge port harness connector.
4.Also check for short circuit between wires.
Is the inspection result normal?
YES- INSPECTION END
NO- Replace quick charge port. Refer to "Removal and Installation" Removal and Installation.
