ACTIVE STABILIZER SUSPENSION SYSTEM FREEZE FRAME DATA


  1. OUTPUT FREEZE FRAME DATA


    1. The front active stabilizer control ECU assembly and rear active stabilizer control ECU assembly stores the vehicle condition when a DTC is output and this information can be displayed using the GTS.

    2. Freeze frame data when a DTC is output.


      1. When a DTC is output, the freeze frame data at the time the DTC is output is stored.

      2. When freeze frame data is stored when a DTC is output, the data is not updated or deleted until the DTCs are cleared.

  2. CHECK FREEZE FRAME DATA


    1. Front Active Stabilizer Control ECU Assembly:


      1. Turn the engine switch off.

      2. Connect the GTS to the DLC3.

      3. Turn the engine switch on (IG).

      4. Turn the GTS on.

      5. Enter the following menus: Chassis / Front Stabilizer / Trouble Codes.


        Chassis > Front Stabilizer > Trouble Codes
      6. Select a DTC to display the freeze frame data.

      7. Check the freeze frame data for the output DTC.
