INSPECT AIR SWITCHING VALVE ASSEMBLY

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) 4.5 to 5.5 Ω 1 - Body ground Always 1MΩ or higher 2 - Body ground

   Tech Tips

   When measuring the resistance make sure that the surface temperature of the air switching valve assembly is 20°C (68 °F).

   If the resistance is not as specified, replace the air switching valve assembly.

2. Check the operation of the air switching valve assembly.

      *a	Port A
      *b	Port B
      	Air

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

      Note

      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.

      Apply battery voltage across terminals 1 and 2.

      Note

      Apply voltage for 2 minutes or less.

   3. Check that air flows from port A to port B.

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