  1. INSPECT VACUUM SWITCHING VALVE (for ACIS)


    1. A01IPZ3E01

      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) 27 to 33 Ω
      1 - Body ground Always 1 MΩ or higher
      2 - Body ground

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

    2. Check the VSV operation.


      1. A01IU30E01

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