CAUTION / NOTICE / HINT

Note:

  • When replacing the ECM, the ECM needs Registration and Initialization (Click here).

  • After replacing the swirl control valve, the ECM needs initialization (Click here).

Tip:

  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • 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 (ACTUATOR TEST OF SWIRL FLAP)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Start the engine.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Actuator Test of Swirl Flap / Data List / Swirl Valve Actuator Position.

      OK

      The value of "Swirl Valve Actuator Position" changes according to the amount "Actuator Test of Swirl Flap" is operated, and the swirl flap operates smoothly.

  2. CHECK HARNESS AND CONNECTOR (SWIRL CONTROL VALVE - ECM)

    1. Disconnect the swirl control valve connector.

    2. Disconnect the ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

  3. REPLACE SWIRL CONTROL VALVE

    1. Replace the swirl control valve (Click here).

    2. Perform the swirl valve learning value reset (Click here).

  4. CHECK WHETHER DTC OUTPUT RECURS (DTC P1477, P2008, P2009 AND/OR P2010)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Clear the DTCs (Click here).

    4. Turn the ignition switch off and wait for 60 seconds or more [A].

    5. Perform road test [B].

    6. Repeat [A] and [B] for the number of trips detected.

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

    8. Read the DTCs.
