POWER STEERING SYSTEM FREEZE FRAME DATA


  1. FREEZE FRAME DATA

    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 if the values are within specifications.

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


    1. Turn the ignition switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON (IG).

    4. Turn the GTS on.

    5. Check the freeze frame data on the GTS.
