        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 20°C (68°F) 33 to 39 Ω

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

    2. A01VFXB

      Check VSV operation.


      1. Check that air does not flow from the port as shown in the illustration.

        If the result is not as specified, replace the VSV assembly.

      2. A01VKQS

        Apply battery voltage across the terminals.
