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 VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE)


    1. A01DYH1E05

      Connect an intelligent tester to the DLC3.

    2. Disconnect the vacuum hoses from the VSV for swirl control valve.

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

    4. Select the following menu items: Powertrain / Engine and ECT / Active Test / Activate the VSV for Swirl Control Valve.

    5. Check the operation.

      OK
      When VSV for swirl control valve is ON, air from port E flows out through port F.
      When VSV for swirl control valve is OFF, air from port E flows out through air filter.

    OK

    CHECK FOR INTERMITTENT PROBLEMS

    NG

  2. INSPECT VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE (RESISTANCE)


    1. A01E1L1E06

      Disconnect the S9 vacuum hoses from the VSV for swirl control valve connector.

    2. Measure the resistance of the VSV.

      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 37 to 44 Ω

    NG

    REPLACE INTAKE MANIFOLD

    OK

  3. INSPECT VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE (POWER SOURCE VOLTAGE)


    1. A01E2WVE04

      Disconnect the S9 vacuum hoses from the VSV for swirl control valve connector.

    2. Turn the ignition switch ON.

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

      Standard voltage
      Tester Connection Specified Condition
      VSV for swirl control valve (S9-1) - Body ground 11 to 14 V

    OK

    CHECK HARNESS AND CONNECTOR (VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE - ECM) Click here

    NG

  4. CHECK HARNESS AND CONNECTOR (NO. 1 INTEGRATION RELAY (MAIN RELAY) - VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE)


    1. A01DYGSE21

      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 connector.

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

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

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

    REPAIR OR REPLACE POWER SOURCE CIRCUIT COMPONENTS

  5. CHECK HARNESS AND CONNECTOR (VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE - ECM)


    1. A01DYD0E02

      Disconnect the S9 VSV connector.

    2. Disconnect the E6 ECM connector.

    3. Check the resistance.

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

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

    REPLACE ECM
