INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (LandCruiser RM0000012XK0ARX.html) and initialization (LandCruiser RM000000TIN08CX.html).
HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition 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)
Land Cruiser, Land Cruiser Prado. Grj150 Trj150,155 Kdj150,155 Lj150, Gdj150,155.1Kd-Ftv Engine Control.Ecd System. Dtc P2009 Intake Manifold Runner Control Circuit Low (Bank 1)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to 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

  1. Reconnect the vacuum hoses.
