Tech Tips

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. PERFORM ACTIVE TEST USING GTS (ACTIVATE THE VSV FOR SWIRL CONTROL VALVE)


    1. B003OFUC02

      Connect the GTS to the DLC3.

    2. Disconnect the vacuum hoses from the vacuum switching valve (for swirl control valve).

    3. Turn the ignition switch to ON and turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the VSV for Swirl Control Valve.

    5. Check the VSV operation when it is operated using the GTS.


      Powertrain > Engine > Active Test
      Tester Display
      Activate the VSV for Swirl Control Valve
      OK
      GTS Operation Specified Condition
      VSV ON Air from port E flows out through port F
      VSV OFF Air from port E flows out through air filter

    6. Reconnect the vacuum hoses.
