POWER STEERING SYSTEM (for 2GR) FREEZE FRAME DATA

  1. FREEZE FRAME DATA

    Note

    • It is difficult to show the specified values (judgment values) clearly because freeze frame data values change significantly due to differences in measurement conditions, surroundings, or vehicle conditions. For this reason, there may be a problem even when the values are within specifications.

    • Turn the engine switch on (IG) and park the vehicle on level ground. Check the freeze frame data by using the Techstream.

    1. Turn the engine switch off.

    2. Connect the Techstream to the DLC3.

    3. Turn the engine switch on (IG).

    4. Turn the Techstream on.

    5. Check the freeze frame data on the Techstream.
