VACUUM SWITCHING VALVE(for ACIS) INSPECTION

PROCEDURE


  1. INSPECT NO. 1 VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)


    1. B004LWXC01
      *a Valve Body
      *b

      Component without harness connected

      (No. 1 vacuum switching valve assembly (for ACIS))

      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) 33 to 39 Ω
      1 - No. 1 vacuum switching valve assembly (for ACIS) body ground Always 10 kΩ or higher
      2 - No. 1 vacuum switching valve assembly (for ACIS) body ground

      If the result is not as specified, replace the No. 1 vacuum switching valve assembly (for ACIS).

    2. Check the No. 1 vacuum switching valve assembly (for ACIS) operation.


      1. B004K5JC01
        *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 No. 1 vacuum switching valve assembly (for ACIS).

      2. B004JXDC01
        *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 No. 1 vacuum switching valve assembly (for ACIS).
