        Component without harness connected

        (No. 1 vacuum switching valve)

        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 - Body ground Always 10 kΩ or higher
        2 - Body ground

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

    2. Check the operation of the vacuum switching valve.

        *2 Filter
        *a Air

        Check that air flows from port E to the filter.

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

    3. Apply battery voltage across the terminals.
