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)

    A003FT0E16

    1. Connect the GTS to the DLC3.

    2. Disconnect the vacuum hoses from the vacuum switching valve (for No. 1 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.

      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.


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


    1. Inspect the vacuum switching valve (for No. 1 swirl control valve) Click here.


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

      (to Vacuum Switching Valve (for No. 1 Swirl Control Valve))

      Disconnect the vacuum switching valve (for No. 1 swirl control valve) connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      D67-2 - Body ground Ignition switch ON 11 to 14 V
    3. Reconnect the vacuum switching valve (for No. 1 swirl control valve) connector.


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


    1. Disconnect the vacuum switching valve (for No. 1 swirl control valve) connector.

    2. Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D67-1 - D99-108 (SCV) Always Below 1 Ω
      D67-1 or D99-108 (SCV) - Body ground Always 10 kΩ or higher
    4. Reconnect the vacuum switching valve (for No. 1 swirl control valve) connector.

    5. Reconnect the ECM connector.


    NG
    OK
  5. REPLACE ECM


    1. Replace the ECM Click here.

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


    1. Remove the No. 1 integration relay from the No. 1 engine room relay block and junction block assembly.

    2. Disconnect the vacuum switching valve (for No. 1 swirl control valve) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      10B-4 - D67-2 Always Below 1 Ω
      10B-4 or D67-2 - Body ground Always 10 kΩ or higher
    4. Reinstall the No. 1 integration relay.

    5. Reconnect the vacuum switching valve (for No. 1 swirl control valve) connector.


    NG
    OK
  7. INSPECT ECM POWER SOURCE CIRCUIT


    1. Check the ECM power source circuit Click here.


    NEXT
  8. REPLACE VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE)


    1. Replace the vacuum switching valve (for No. 1 swirl control valve).


    NEXT
  9. REPAIR OR REPLACE HARNESS OR CONNECTOR


    1. Repair or replace harness or connector.


    NEXT
  10. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. Connect the GTS to the DLC3.

    2. Clear the DTCs Click here.

    3. Start the engine and wait for 3 seconds or more.

    4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
