PLUG-IN CHARGE CONTROL SYSTEM FREEZE FRAME DATA


  1. FREEZE FRAME DATA

    Tech Tips

    The plugin charge control ECU assembly records vehicle and driving condition information as freeze frame data the moment a DTC is stored. Freeze frame data is used to determine the condition of the vehicle at the time the malfunction occurred and to perform a reproduction test. When checking the information codes for the plug-in charge control system, refer to Detail Code 1 to 5.


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Plug-in Control / Trouble Codes.

    5. Select a DTC in order to display its freeze frame data.

    6. Check the freeze frame information recorded with the DTC.
