Description

Quick charger communication is a serial communication line for real time application. It is a multiplex communication line with high data communication speed and excellent error detection ability. On-board charger and quick charger are connected with two communication lines (quick charger communication H-line and quick charger communication L-line) and transmit/receive data.


DTC Logic


DTC DETECTION LOGIC


CAUTION:
This DTC may be detected if there is a malfunction in the quick charger. Check that the quick charger is normal when this DTC is detected.






DTC CONFIRMATION PROCEDURE

Check intermittent incident. Intermittent Incident.
Is the inspection result normal?
YES- Replace on-board charger. Removal And Installation.
NO- Repair or replace error-detected parts.


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.
- 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. 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. Service and Repair (without Li-ion battery heater models), Service and Repair (with Li-ion battery heater models).
2.Disconnect high voltage harness connector from front side of Li-ion battery. Service and Repair (without Li-ion battery heater models), Service and Repair (with Li-ion battery heater models).
3.Measure voltage between high voltage harness connector terminals.











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. 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. Removal and Installation.
