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 or suction control valve, 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 intelligent tester. 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 NO. 2 VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE ASSEMBLY) (RESISTANCE)


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


    NG

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

    OK

  2. CHECK TERMINAL VOLTAGE (NO. 2 VACUUM SWITCHING VALVE ASSEMBLY (FOR SWIRL CONTROL VALVE) POWER SOURCE)

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

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

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      V7-2 (+B) - Body ground Ignition switch ON 11 to 14 V

    NG

    CHECK HARNESS AND CONNECTOR (NO. 2 VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE ASSEMBLY) - EFI MAIN RELAY HOLDER) Click here

    OK

  3. CHECK HARNESS AND CONNECTOR (NO. 2 VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE ASSEMBLY) - ECM)


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

    2. Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      V7-1 (SCV2) - E10-3 (SCV2) Always Below 1 Ω
      V7-1 (SCV2) or E10-3 (SCV2) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR Click here

    OK

  4. REPLACE ECM


    1. Replace the ECM Click here.

    CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED Click here

  5. CHECK HARNESS AND CONNECTOR (NO. 2 VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE ASSEMBLY) - EFI MAIN RELAY HOLDER)


    1. Remove the EFI MAIN relay from the engine room relay block.

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

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      EFI MAIN relay holder 3 - V7-2 (+B) Always Below 1 Ω
      EFI MAIN relay holder 3 or V7-2 (+B) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR Click here

    OK

    1. Check the ECM power source circuit Click here.


    NEXT

    CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED Click here

  7. REPLACE NO. 2 VACUUM SWITCHING VALVE (FOR SWIRL CONTROL VALVE ASSEMBLY)


    1. Replace the No. 2 vacuum switching valve (for swirl control valve assembly).


    NEXT

    CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED Click here

  8. REPAIR OR REPLACE HARNESS OR CONNECTOR


    1. Repair or replace harness or connector.


    NEXT

  9. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. Connect the intelligent tester to the DLC3.
