HYBRID CONTROL SYSTEM INFORMATION / FREEZE FRAME DATA


  1. FREEZE FRAME DATA

    Tech Tips

    The hybrid vehicle control ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored. It can be used for estimating or duplicating the vehicle conditions that were present when the malfunction occurred. To confirm the details of the hybrid control system, check the detailed information for the DTC information code in the Data List (INF code).


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Select the following menu items: Powertrain / Hybrid 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.
