PROCEDURE


  1. TAKE SNAPSHOT DURING IDLING AND 4000 RPM (PROCEDURE 1)


    1. Connect the GTS to the DLC3.

    2. Start the engine and turn the GTS on.

    3. Enter the following menus: Powertrain / Engine and ECT / Data List / All Data.

    4. Take a snapshot of the following Data List items.

      Tech Tips


      • A snapshot can be used to compare vehicle data from the time of the malfunction to normal data and is very useful for troubleshooting. The data in the list below is that of a normal vehicle, but as the data varies between individual vehicles, this data should only be used for reference.

      • Check the Data List at idling and at 4000 rpm with no load after the engine is warmed up.

  2. READ VALUE USING GTS (CATALYST DIFFERENTIAL PRESS)


    1. Check Catalyst Differential Press in the snapshot taken in procedure 1 when the engine was running at 4000 rpm with no load.

      Result
      Result Proceed to
      Catalyst Differential Press is more than 0.27 A
      Except above B
