Information / Freeze Frame Data

  1. FREEZE FRAME DATA 

    HINT:

    The freeze frame data records the driving condition when the DTC was set. It is used for estimating or simulating the condition of the vehicle when the malfunction occurred. To check the details of the hybrid vehicle control system, check the detailed information for the DTC (Information).

    1. Connect the intelligent tester to the DLC3.
    2. Turn the power switch ON (IG).
    3. Turn the intelligent tester ON.
    4. Enter the following menus: DIAGNOSIS / OBD/ MOBD / HV ECU / DTC INFO / CURRENT CODES.
    5. Select a DTC in order to display its freeze frame data.
    6. Check the freeze frame data of the DTC that has been detected.
    7. Check information of the DTC (see below).
