  1. 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)
    		11 to 13 Ω
    1 - Body ground
    2 - Body ground

  1. Check operation of the E-VRV.

    1. When a vacuum of 67 kPa (500 mmHg, 19.7 in.Hg) is applied to port F, check that air flows from port E to the filter.
