VACUUM SWITCHING VALVE(for ACIS) ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)


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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 37 to 44 Ω
      1 - Body ground Always 1 MΩ or higher
      2 - Body ground

      If the result is not as specified, replace the vacuum switching valve assembly.

    2. Check the vacuum switching valve operation.


      1. A00YURIC01
        *1 Port E
        *2 Filter
        A00YXOY Air

        When vacuum is applied to port E, check that air is sucked into the filter.

        If the result is not as specified, replace the vacuum switching valve assembly.

      2. A00YXV4C01
        *1 Port F
        *2 Port E
        A00YXOY Air

        Apply battery voltage across the terminals. When vacuum is applied to port F, check that air is sucked into port E.

        If the result is not as specified, replace the vacuum switching valve assembly.
