INSPECTION PROCEDURE

Note


  • Inspect the fuses of circuits related to this system before performing the following inspection procedure.

  • After replacing the ECM, the new ECM needs registration Click here and initialization Click here.

  • After replacing the fuel supply pump assembly, the ECM needs initialization Click here.

  • After replacing an injector assembly, the ECM needs registration Click here.

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


    1. Inspect the vacuum switching valve (for No. 2 swirl control valve) Click here.


    NG

    REPLACE VACUUM SWITCHING VALVE (FOR NO. 2 SWIRL CONTROL VALVE) Click here

    OK

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

      (to Vacuum Switching Valve (for No. 2 Swirl Control Valve))

      Disconnect the vacuum switching valve (for No. 2 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
      D91-2 - Body ground Ignition switch ON 11 to 14 V

    NG

    CHECK HARNESS AND CONNECTOR (VACUUM SWITCHING VALVE (FOR NO. 2 SWIRL CONTROL VALVE) - NO. 1 INTEGRATION RELAY) Click here

    OK

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


    1. Disconnect the vacuum switching valve (for No. 2 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
      D91-1 - D99-107 (SCV2) Always Below 1 Ω
      D91-1 or D99-107 (SCV2) - Body ground Always 10 kΩ or higher

    4. Reconnect the vacuum switching valve (for No. 2 swirl control valve) connector.

    5. Reconnect the ECM connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR Click here

    OK

  4. REPLACE ECM


    1. Replace the ECM Click here.

  5. CHECK HARNESS AND CONNECTOR (VACUUM SWITCHING VALVE (FOR NO. 2 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. 2 swirl control valve) connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      10B-4 - D91-2 Always Below 1 Ω
      10B-4 or D91-2 - Body ground Always 10 kΩ or higher

    4. Reinstall the No. 1 integration relay.

    5. Reconnect the vacuum switching valve (for No. 2 swirl control valve) connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR Click here

    OK

  6. CHECK ECM POWER SOURCE CIRCUIT


    1. Check the ECM power source circuit Click here.


    NEXT
