1. INSPECT AIR SWITCHING VALVE ASSEMBLY


    A158642

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 5
    		20°C (68°F)*
    		4.5 to 5.5 Ω
    1 - Body ground
    		Always
    		1 MΩ or higher
    5 - Body ground

    HINT:
    *: Make sure that the air switching valve is at ambient temperature before measuring the resistance.

    NOTICE:
    When applying voltage, do not touch terminals 2, 3 and 4.
    If the result is not as specified, replace the air switching valve assembly.

  1. Check the operation of the air switching valve.

    1. Check that air does not flow from port A to port B.

      NOTICE:
      Make sure the applied pressure is 30 kPa (0.3 kgf/cm2, 4.4 psi) or less
      If the result is not as specified, replace the air switching valve assembly.


      2. A158644E01

    2. Apply battery voltage across terminals 1 and 5.

      NOTICE:
      When applying voltage, do not touch terminals 2, 3 and 4.

    3. Check that air flows from port A to port B.
      If the result is not as specified, replace the air switching valve assembly.
