POWER STEERING SYSTEM FREEZE FRAME DATA


  1. FREEZE FRAME DATA

    Note


    • It is difficult to show the specified values (judgement 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 intelligent tester.


    1. Turn the engine switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the engine switch on (IG).

    4. Turn the intelligent tester on.

    5. Check the freeze frame data by following the prompts on the intelligent tester. Enter the following menus: Chassis / EMPS / Trouble Codes.
