CAUTION:

Use the check board when measuring the ECM terminal voltage and resistance. Ref. to  ENGINE (DIAGNOSTICS) (H4DOTC)>GENERAL DESCRIPTION>PREPARATION TOOL>HOW TO USE CHECK BOARD 

NOTE:

After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Ref. to  ENGINE (DIAGNOSTICS) (H4DOTC)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE 

  1. CHECK HARNESS BETWEEN ECM AND TUMBLE GENERATOR VALVE ACTUATOR RH CONNECTOR (SHORT TO POWER SUPPLY)  .
    1. Turn the ignition switch to OFF.
    2. Disconnect the connector from ECM.
    3. Turn the ignition switch to ON.
    4. Measure the voltage between ECM connector and engine ground.

      Connector & terminal 

      (E51) No. 43 (+) - Engine ground (-):

      (E51) No. 44 (+) - Engine ground (-):

    Is the voltage 5 V or more?

    Yes  : Repair the short circuit to power in harness between ECM connector and tumble generator valve actuator RH connector.

    No  : Replace the tumble generator valve actuator RH. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>TUMBLE GENERATOR VALVE ACTUATOR

    NOTE:

    The tumble generator valve actuator cannot be disassembled.
