P320F-660 On-Board Charger System Malfunction

DESCRIPTION

Refer to the description for DTC P0D5C-847 Click here.

DTC No. INF Code DTC Detection Condition Trouble Area
P320F 660 Charger operation cannot be stopped or charge control power (WIN) is exceeded because charging power cannot be adjusted.

  • Electric vehicle charger assembly

  • Plugin charge control ECU assembly

INSPECTION PROCEDURE

CAUTION:


  • Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly or electric vehicle charger assembly, turn the power switch off. Also, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

  • After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work Click here.

    Tech Tips

    Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly and electric vehicle charger assembly.

Note

After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Click here.

Tech Tips

After the repair, check that the Data List item [State of Charge (All Bat)] is 25% or less, then plug-in charge the vehicle until it completes and check that DTCs are not output.
