VACUUM SWITCHING VALVE(for ACIS) INSPECTION

PROCEDURE


  1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)


    1. A018LENC01
      *a Valve Body

      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 - Valve body Always 10 kΩ or higher
      2 - Valve body

      If the result is not as specified, replace the vacuum switching valve assembly (for ACIS).

    2. Check the vacuum switching valve assembly (for ACIS) operation.


      1. A018IHLC04
        *a Filter
        *b Port (E)
        *c Air

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

        If the result is not as specified, replace the vacuum switching valve assembly (for ACIS).

      2. A018LOUC03
        *a Port (E)
        *b Port (F)
        *c Air

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

        If the result is not as specified, replace the vacuum switching valve assembly (for ACIS).
