Tech Tips

Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


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

    A01DYH1E05

    1. Connect the intelligent tester to the DLC3.

    2. Disconnect the vacuum hoses from the VSV for No. 1 swirl control valve.

    3. Turn the ignition switch ON and turn the tester ON.

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

    5. Check the VSV operation when it is operated using the intelligent tester.

      OK
      Tester 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

    OK
    NG
  2. INSPECT VACUUM SWITCHING VALVE FOR NO. 1 SWIRL CONTROL VALVE (RESISTANCE)


    1. A01DVMNE06

      Disconnect the S9 VSV for No. 1 swirl control valve connector.

    2. Measure the resistance of the VSV for No. 1 swirl control valve.

      Standard resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 33 to 39 Ω

    NG
    OK
  3. INSPECT VACUUM SWITCHING VALVE FOR NO. 1 SWIRL CONTROL VALVE (POWER SOURCE VOLTAGE)


    1. A01E2WVE08

      Disconnect the S9 VSV for No. 1 swirl control valve connector.

    2. Turn the ignition switch ON.

    3. Measure the voltage of the wire harness side connector and body ground.

      Standard voltage
      Tester Connection Specified Condition
      S9-2 - Body ground 11 to 14 V

    OK
    NG
  4. CHECK HARNESS AND CONNECTOR (VSV FOR NO. 1 SWIRL CONTROL VALVE - NO. 1 INTEGRATION RELAY)

    A01DYGSE18

    1. Remove the NO. 1 integration relay from the engine room junction block Click here.

    2. Disconnect the 1J No. 1 integration relay connector.

    3. Disconnect the S9 VSV for No. 1 swirl control valve connector.

    4. Measure the resistance of the wire harness side connectors.

      Standard resistance (Check for open)
      Tester Connection Specified Condition
      1J-5 - S9-2 Below 1 Ω
      Standard resistance (Check for short)
      Tester Connection Specified Condition
      1J-5 or S9-2 - Body ground 10 kΩ or higher

    NG
    OK
  5. CHECK HARNESS AND CONNECTOR (VACUUM SWITCHING VALVE FOR NO. 1SWIRL CONTROL VALVE - ECM)


    1. A01DXS7E07

      Disconnect the S9 VSV for No. 1 swirl control valve connector.

    2. Disconnect the E8 ECM connector.

    3. Measure the resistance of the wire harness side connector.

      Standard resistance (Check for open)
      Tester Connection Specified Condition
      S9-1 - SCV (E8-15) Below 1 Ω
      Standard resistance (Check for short)
      Tester Connection Specified Condition
      S9-1 or SCV (E8-15) - Body ground 10 kΩ or higher

    NG
    OK
