STOP AND START SYSTEM FREEZE FRAME DATA


  1. DESCRIPTION

    The engine stop and start ECU records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, as well as other data recorded at the time of a malfunction.

    Note


    • Freeze frame data values will vary depending on the measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even when the values are within specifications.

    • Turn the ignition switch to ON and park the vehicle on level ground. Check the freeze frame data using the intelligent tester.


    1. Turn the ignition switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the ignition switch to ON.

    4. Turn the tester on.

    5. Check for DTCs and read the freeze frame data.
