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 when the values are within specifications.

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


    1. Turn the power switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the power switch on (IG).

    4. Turn the intelligent tester on.

    5. Check the freeze frame data on the intelligent tester.
