INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (Toyota Fortuner RM0000012XK04BX.html) and initialization (Toyota Fortuner RM000000TIN04NX.html).
HINT:
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 moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (ACTIVATE THE VSV FOR SWIRL CONTROL VALVE)
Toyota Fortuner. Ggn50, 60 Kun51, 61 Tgn51 Lan50.1Kd-Ftv Engine Control System.Ecd System. Dtc P2009 Intake Manifold Runner Control Circuit Low (Bank 1)

  1. Connect the intelligent tester to the DLC3.

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

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

  1. Enter the following menus: Powertrain / Engine and ECT / Active Test / Activate the VSV for Swirl Control Valve.

  1. Check the VSV operation when it is operated using the intelligent tester.

    OK:
    Tester 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


OK
CHECK FOR INTERMITTENT PROBLEMS (Toyota Fortuner RM0000012X400RX.html)
