VACUUM SWITCHING VALVE(for ACIS) ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)


    1. Disconnect the vacuum switching valve connector.

    2. 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.

    3. Check the vacuum switching valve operation.

        Battery positive (+) → Terminal 1

        Battery negative (-) → Terminal 2

        		 Air is sucked into port E when a vacuum is applied to port F

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

    4. Connect the vacuum switching valve connector.
